Different Reactions From The Brine Shrimp Biology Essay

Different Reactions From The Brine Shrimp Biology Essay The objective of the Pharmacology Lab is to find the lethal chemical(s) or the LD50 relevant to a certain genus. In order for a chemical to be considered the LD50, 50% of the population of the organism present in a container must die. A total of three trials and four tests are completed to determine whether or not the chemical has the ability to kill the brine shrimp. The three trials contain 5mL of the chemical in each container, while the four tests have different amounts of the chemical in each container. The amount of water used for both the trials and tests remain constant at 40mL. Once the correct amount of the required substances and brine shrimp are placed into their respective and labeled containers for both trials and tests, they are then moved under a desk light. For the next duration of time, the death rate of the brine shrimp and the physical or behavioral changes visible are observed and recorded. After performing the experiments, the data shows that a great number of t hese selected regular household items have deadly chemicals in them that can kill other living organisms if given the right amount of dosage, including humans. Out of all five products, the LD50 was only found in soda and hydrogen peroxide. Lemon juice, nail polish remover, and hand sanitizer were not considered the LD50 because the death rate percentage was higher than 50%. This research provides a better understanding of how toxic household chemicals are. Products that were created for consuming such as the Lemon Juice and Soda were found to instantly and over a certain amount of time, kill the brine shrimp once in contact. II. Introduction In this experiment, one of the main purposes is to find the LD50 of several household chemicals on Brine Shrimp. LD means lethal dose of a certain product. The LD50 formula gives the estimate of deaths of half a population when receiving the molarity of each chemical. A possible solution to this problem is to perform and experiment where an organism is tested on with different types of chemicals for the death rate. Brine shrimp, the genus used, are aquatic crustaceans that can be grown by adding water and brine shrimp eggs into a tank. This process takes approximately two days. Brine shrimp lives in salt water, but can also survive in regular water for 24 hours. Completing this experiment determines whether they can survive a certain about of chemicals in different time intervals. This lab contains five different chemicals including: nail polish remover, hydrogen peroxide, lemon juice, hand sanitizer, and lemon soda. These household chemicals are tested as the positive controls, whil e the negative control is water. With five positive controls, there would be different results from each chemical. As the experiment takes place through four tests; each containing 3 trials; the observation of the deaths of brine shrimp demonstrates the amount of time they can survive in new obscure habitats. The test of each chemical shows whether there are traces of deadly substances, which could help find the measures of toxicity in each chemical. Testing the toxicity by molarity and time shows the maximum amount of toxicity that humans can handle to be able to survive. The experiment is an example of how living organisms react to chemicals. The brine shrimp will play the role of the organism. However, different organisms will have different reactions depending on their adaptations and physical traits. As the brine shrimp take in the chemicals, the inability to survive increases. The death of the aquatic crustaceans shows how toxic harmless household chemicals can truly be.This lab will explore the ingredients from the five chemicals used. The observations of the LD50 will determine which chemical is deadlier than the others, causing the public to be more aware of these fatal factors. III. Methods: The brine shrimp are grown by adding water and brine shrimp eggs into a tank. Brine shrimp takes two days to mature enough to be experimented on. The lethal chemical(s) or the LD50 are found by placing different substances mixed with water into containers with nine brine shrimp. Through a series of tests and trials, the lethal chemicals are distinguished. A total of three trials and four tests are completed to determine whether or not the chemical has the ability to kill the brine shrimp. The three trials contain 5ml of the chemical in each container, while the four tests have different amounts of the chemical in each container; (5ml, 10ml, 15ml, and 20ml). The amount of water used for both the trials and tests remain constant at 40ml. Once the correct amount of the required substances the brine shrimp are placed into their labeled containers for both trials and tests. Next, the Brine shrimp are moved under a desk light because they are attracted to any form of light. The death rate and physical or behavioral changes of the brine shrimp are observed and recorded in tests with intervals of 10-minute trials and 5-30 minutes. This lab consists of four tests and three trials for five different chemicals to find the LD50. The positive controls include: Super Chill Lemon Lime soda, hydrogen peroxide, House Recipe lemon juice, 2.2 oz. of Assured Aloe Vera scented hand sanitizer and 2.2 oz. of ONYX Professional lavender scented nail polish remover, while the negative control is water throughout the entire experiment. For each test, there are three trials performed beforehand. Twenty seven brine shrimp are needed for the trials. For each of the three trials, nine brine shrimp are obtained from the twenty seven. Then, 40mL of distilled water is added to the brine shrimp container through pipettes and graduated cylinders; the total volume of water for each trial is 40mL in order to maintain consistency. From each chemical, 5mL are added into the labeled containers of the 40 mL distilled water. Once all substances are added, the containers are placed under direct light from a desk lamp because brine shrimp are att racted to light. Through five tests after the three trials, various amounts of nail polish remover, hydrogen peroxide, lemon juice, hand sanitizer, and Sprite soda are added to its assigned containers. For each test, there will be four containers for the different amounts used of each chemical. The first container contains 5mL of the chemical while the other three containers will have an increase of 5mL from the prior container. This process will be done five times for the five chemicals used. The counts of deceased shrimp after each time interval are recorded over a course of 5 minutes to 30 minutes in percentages. Different reactions from the brine shrimp were recorded in the data table as well as pictures being taken. This procedure was used according to the outline given in order to achieve the objective of this lab. Given a certain the amount of time, three trials and four tests were used. In the procedure, several changes were included, instead of adding 40ml of water with the nine brine shrimp, 40ml of water was added to the desired chemical first to have enough time to collect the brine shrimp for the specific trial and test.

Analysis The LD50 for hydrogen peroxide is approximately 0.24 molars. Hydrogen peroxide has 3% Hydrogen Peroxide (Stabilized), Purpose First Aid Antiseptic/Oral Debriding Agent. Its Inactive Ingredient is Purified Water. Hydrogen peroxide is a deteriorizing agent that is commonly used as a hair bleach when diluted. An Oral debriding agent describes what the hydrogen peroxide can do. This means that the hydrogen peroxide when diulted in water can help heal minor mouth and gum irritation. Since all living organisms have an enzyme called peroxidase, it helps decompose low concentrations hydrogen peroxide into water and oxygen. . There is no LD50 for nail polish remover. Nail Polish remover has the ingredients: Acetone, aqua, denatonium benzoate, tocopheryl acetate, aloe barbadensis leaf juice, parfum(means perfume in french), Cl 45410(dye), Cl 60730(dye). Denatonium benzoate is a chemical compound known to prevent and discourage people from drinking harmful products. Tocopheryl acetate, also known as vitamin E acetate provides beneficial antioxidant effects. Aloe barbadensis leaf juice, also know as Aloe Vera is a plant. When consumed, it can help relieve irritable bowel syndrome and heartburn. Acetone is an organic compound that is a colorless and flammable liquid. Concluding that acetone is the lethal ingredient and causes the death of the brine shrimp when ingested, it will cause liver problems, which causes the liver to have a hard time breaking them down. Large intake of acetone can lead to unconsciousness and death. There was no LD50 for Lemon; the ingredients in the lemon juice packets include water, lemon juice concentrate, sodium benzoate, sodium bisulfite, and lemon oil. Sodium Benozoate is a type of salt often used a preservative because it works well at killing bacteria, yeast, and fungi. Sodium bisulfite is a food addictive. When in contact with chlorine bleach, it will release harmful fumes.The brine shrimp died within 20 minutes because of the sodium benzoate in the lemon juice packet, which is a type of salt mixed together with vitamin C causes a carcinogen substance called benzene. Benzene is a carcinogen because when exposed into the air, it can cause leukemia. Eating or drinking substances with high levels of benzene can cause vomiting, dizziness, sleepiness, and or death. It may not be lethal enough to kill humans yet, but having a high amount of the lemon juice packets can potentially kill a human or any living organism. There is no LD50 for Hand Sanitizer but the graph decreases and increases because there was a slight change in the number of brine shrimp needed in each container. The ingredients contained in this chemical are: water, triethanolamine, glycerin, propylene glycol, aloe barbadensis gel(another form of aloe vera), carbomer, fragrance, blue 1(dye), yellow 5(dye), and 62% ethyl alcohol. Triethanolamine is a chemical compound that occasionally causes contact allergy. Glycerin is a simple alcohol compound that is used as a sweetener and sometimes a preservative in food and beverages. Propylene glycol is an organic compound used in many applications such as a food addictive called E number 1520, moisturizer in medicine, and a solvent for food coloring. Carbomer is a synthetic polymer that forms an adhesive eye gel. 62% ethyl alcohol is a flammable liquid used as solvents and fuel. The brine shrimp died because of the 62% ethyl alcohol in the hand sanitizer, when consumed can cause death. Alt hough used in wine and any alcoholic drinks, the drinks only contain small concentrations of alcohol, legal enough to drink. The LD50 for Super chill lemon lime soda is approximately 0.19 molars. The ingredients in the soda are carbonated water, high fructose corn syrup, citric acid, natural flavors, potassium citrate and potassium benzoate. High frutose corn syrup is comprised of many corn syrups that has undergone enzymatic(enzymes that catalyze) process that converts glucose into frutose for desired sweetness. There have been health concerns about raising the risks of diabetes and cardiovascular disease. Citric acid is a weak organic acid that is a natural preservative and used to add a sour taste to food and soft drinks. Contact with dry citric acid can result in skin or eye irritation. potassium citrate is a food addictive and used to regulate acidity. It is also a potential health hazard when administered incorrectly. Elevated blood levels of potassium citrate can result in heart attacks and death. Potassium benzoate is a food preservative that inhibits the growth of yeast, mold, and some bacteria. T he reason why the brine shrimp died because of potassium citrate in the soft drink. Too much potassium citrate can cause irregular heartbeat and a risk of having a heart attack. Although there are potassium citrate pills sold in stores, they are only recommended if the person had been having a case of fatigue or muscle weakness. The kidney is responsible for eliminating excess potassium in the body. The molarity formula: iM1V1=1M2V2 was used to find the LD50 and true concentration of each chemical after all the substance has been added to container and totaled. The LD50 for Hydrogen Peroxide is 0.24 molars. The LD50 for Super Chill lemon lime soda is 0.19 molars. There are no LD50 for lemon, nail polish remover, and hand sanitizer because the deaths were higher than fifty percent. The standard deviation at 20 ml for Hydrogen Peroxide is approximately 0.833, for Nail Polish remover, lemon, hand sanitizer, and soda is 0. The chemicals included in this experiment are normally used in everyday use in the household. Chemicals such as peroxide are used to clean injuries or cuts. Hand sanitizer is used to clean 99.9% of bacteria on hands. Nail polish remover is used for getting the nail polish off of the fingernails. Lemon juice packets are used in making the dressing for a salad. The LD50 for Nail Polish remover is 1.159 g/kg for humans when digested. Unfortunately, the LD50 for the r est of chemicals are unavailable because they have only been conducted on rats and mice. Although the results of the data were both consistent and gradual in terms of death percentages, a few of the brine shrimp died before 5 minutes of data was recorded. This indicated that the brine shrimp could not live in the high toxicity levels on some of the chemicals used in this experimentation even with the addition of water. VI. Conclusion This lab is significant because the participants are able to discover the true dangers of certain household products such as hydrogen peroxide, soda, hand sanitizer, lemon juice, and nail polish remover. With everyday household chemicals, a personà ¢Ã¢â€š ¬Ã¢â€ž ¢s health can be affected, thus finding the LD50 will tell us how toxic a certain item is. The use of the LD50 is to study the amount of a chemical that will kill 50% of the tested animal, which will show us how dangerous a product can truly be. Some insights include the participants testing the dangers of à ¢Ã¢â€š ¬Ã…“harmlessà ¢Ã¢â€š ¬Ã‚  products. The lab offered similarities and an opportunity for a hands on experience of the procedures a toxicologist, like finding the cause and effects of poison. By using mathematical formulas like the molarity formula and the standard deviation formula, accurate and reliable data was collected to find the true concentration of the LD50 chemicals. For example, the data and calculat ions from these formulas show that one of the chemicals, Hydrogen Peroxide is the LD50 with a molarity of 0.24 molars. The data tables show that chemicals like the lemon juice, nail polish remover, and hand sanitizer are not the LD50. This is most likely due to the fact that these products contain amounts of citric acid and alcohol which results in death rates that are over 50%. In the trials and tests, many occurrences of errors and mistakes which could have affected the outcome of the results. In one of the hand sanitizer tests, 18mL was added into the mixture of substance instead of 20mL. Instead of counting the number of death at a certain time, some of the intervals were missed by a minute or two. This lab was not as accurate as expected because of the difficulties experienced during the beginning of the lab. For example, lotion was one of the chemicals to be tested on the brine shrimp prior to the lab. However, because the lotion was dense, it was difficult to mix with the wat er. Also, the color made it nearly impossible to see and count the brine shrimp. These errors could be easily avoided in the future by double checking the amount of a substance being added, keeping track of time, and using transparent products. For a clearer understanding several alterations of a procedure outline, being careful with the amount of measurements and constant data collection could be applied in the future.

A Comparison of the Writing Styles of Mary Austin and Willia Cather Essay

Steve rayburn! ! !Every author has his or her own style of writing in the works he or she produces. Two female British authors, Mary Austin and Willia Cather, both have similar but distinct styles of writing.! !Mary Austin wrote a novel called â€Å"Land of Little Rain† that depicts death valley and the surrounding desert. The landscape of the story is no doubt a desert; sand dunes, small shrubs, will grass, blistering heat, scavengers and very little water. Although the desert can be easily described, Austin goes to great lengths to show the relationships between the subtle changes in  the landscape, behavioral patterns of animals, and even the way plant life grows around the landscape. For example, she describes and almost personi? es the way that the dunes are blown up on themselves that eventually form a shield that protect the grasses and shrubs that grow behind the dunes. Austin takes a blunt picture of the landscape and shapes and sharpens it into a ? uid ecosystem. She shows the vibrance of life that exists in the so-called death valley.! !Willia Cather is the author of the novel called â€Å"My Antonia† that follows the path of a boy,  Jim Burden, who moves west and befriends a bohemian family that settles close to his. Jim is a thoughtful, self-aware individual that is very introverted; wandering through the woods and pasture on his horse, his thoughts wandering like he is. Like Austin, Cather uses the landscape to springboard themes and motifs throughout the book, often the scenery being an outward expression of the thoughts and feelings of the characters. For example, the rugged, untamed, potentially dangerous landscape foreshadows the imminent suicide of his friend’s father. The death is also very dangerous because he was the main breadwinner of the family, and without him the family could potentially be trapped in the winds and chill of the landscape themselves. Cather pulls from the scenery but uses it as a garnish rather than the main focus of Austin’s work.! !Although both writers use the landscape to build their stories, they use it very differently. Austin’s story is the landscape, while Cather uses the landscape as an element. The style of both authors have similarities but have distinct differences.

Andy Goldsworthy – Essay

Andy Goldsworthy Andy Goldsworthy is able to create something aesthetically pleasing or conceptually pleasing out of absolutely nothing. He takes what he can from the land and produces sculptures by melting ice together, collecting wood or piling rocks in unique ways. Andy Goldsworthy creates his art using his bare hands alone, and while the art is still standing, he creates his own significant places. His art would often erode or collapse but for the brief time they are standing, his creations show bure beauty and amazement. Andy attempts to get closer to nature in all of his artworks. He portrays to the audience the importance of nature by recreating the different sculptures to remind us of the beauty nature holds. â€Å" â€Å"As with all my work, whether it's a leaf on a rock or ice on a rock, I'm trying to get beneath the surface appearance of things. Working the surface of a stone is an attempt to understand the internal energy of the stone. †- Andy Goldsworthy Goldsworthy tries to keep things simple in what he does. He uses only the materials and tools he is provided with by nature. If it is snowing, he will use the snow as his material, if it is autumn he works with the colours of falling leaves, a falling tree is a source of twigs and branches. Goldsworthy works with the land and not against it. He believes that the he has to learn about the lands surroundings and portray them through his artworks so that when others see the art they instantly feel the emotions of what is around them. He causes us to get sucked into the nature of the artwork and its serenity. â€Å"At its most successful, my ‘touch' looks into the heart of nature; most days I don't even get close. These things are all part of a transient process that I cannot understand unless my touch is also transient-only in this way can the cycle remain unbroken and the process be complete. † -Andy Goldsworthy Touch is an important element in the process of Andy Goldsworthy’s art making. He likes to touch before he places any material in order to get connected with the piece and feel the energy of his artwork. He learns from nature and f the piece doesn’t fit right, it could all come crumbling down. This fragile art is what makes his art so interesting to viewers and is what holds to emotion of the piece. Andy often takes photos of his artwork just after he creates them. He then sells the photos and not the artworks as the artworks often erode or fall. In his photographs, he still manages to portray the emotion seen in all his works. In making this art Goldsworthy must be extremely patient and rely completely on nature. He has had to try again many times after something has not worked and his art has come crashing to the floor. The materials used are very delicate and need to be handled with care, but again, this is what makes his art so interesting and exciting. Andy believes in the way nature can teach you many things and overwhelm you with such grace and beauty. Each of Andy’s artworks provides a story or portrays information in order to make the audience wonder. Andy takes interest in creating land art because of the serenity he produces through nature and because of what he can learn from his art. He is interested in finding the figure or picture to suit that area. He uses subtle amounts of colours in his artworks to create a contrast in what is real and what is art. His artworks vary in size, they could cover large mounts of land or could just consist of a small rock pile behind a tree. The size will vary on what the atmosphere of the land holds. Goldsworthy just works with what he has. Every choice counts in his artworks and he has to take his time to create them but in the end, what he produces is magnificent. Emily Kame Kngwarreye- Emily Kame Kngwarreye is an aboriginal artist who strives on creating her work on the emotions and nature of the land. Her land and the closeness and connection she shares with it inspire her work. Emily is an Elder in Anmatyerre, her aboriginal community, and uses this cultural experience as a basis for her artworks. Her artworks are also based on her lifelong custodianship of the women’s dreaming sites in her clan country Albalkere. The beliefs in the dreamtime stories that have been passed down by ancestors and portray them in her artworks. It was her Dreaming that was the source of the creative power, of her knowledge. So profound was her identification with Alhalkere that it infused her life and her belief system. Alhalkere was the source of her paintings. Even physically, Emily's pierced nose bore homage to the ancestor Alhalkere, a pierced rock standing on the Country of the same name. Emily believed purely in this ancestor and gained the knowledge for her paintings form her belief. | Emily tried to convey her land through her art by using colours and symbols in her artworks. Because of her strong Aboriginal connection with the land, she presented this as her significant place and acknowledged this throughout all of her artworks. Often she would use materials found in the land such as what she painted on or with and sometimes even painted using her hands, but mostly she used paint and a brush. The colours she used were to portray her land and symbolize her connection with the ‘Sunburnt’ country. She would use colours such as warm yellows, reds, pinks and orange to portray her land and chose to represent the nature of the land through rough strokes and dots. Usually she painted what came to mind when she thought about her dreamtime stories or chose to tell the story in her artwork using a number of colours and figures. Her land is what is most important in her belief system and she cherishes her connection with nature and the dreamtime stories. In her artworks, each action is carefully chosen to portray her belief in the land. They demonstrate the connection between Aboriginals and their nature. Emily’s art also displays the relationship between Indigenous Australians and the dreamtime stories they tell which usually involve their land and ancestors. Emily’s art tells the story of her life. It displays her beliefs and inspirations and also the significance of the land in Aboriginal culture. So by looking at her artworks we feel an overwhelming respect for Emily and her heritage. We feel the landscape of her land and the hidden reasures that are held close to her community. Emily’s art displays a sense of pride for her land and helps us to convey the same proudness in our lives. Although some of her artworks display sadness and loss, most demonstrate beauty and love. This sense of happiness enters the viewers mid as soon as they set eyes on her artworks. This feeling is what Emily was trying to convey I her artworks. She tries to capture the unseen beauty of the land and reproduce it so that it is no longer hidden to the viewers eye. Emily paints out of pure adoration to her land.
