If you rely on caffeine to wake up and keep the body going, you are not alone. Caffeine is used by millions of people every day to increase wakefulness, alleviate fatigue, and improve concentration and focus (“Caffeine; How much is too much” pg. 1). If not careful on the amounts taken of this drug, caffeine would result to consequences in the body. Also scientists are starting to prove that caffeine is addicting. Even though caffeine is in most every food or drink, it has to be treated with respect like alcohol, if not, symptoms like increased heart beat and racing thoughts will occur. An animal that is affected by the caffeine is Daphnia. Daphnia, also known as water fleas are distinct living organisms of the Animal Kingdom. They are Microorganisms, with a heart that works much like ours. Most distinctly known for their clear body, someone can see almost all their organs just by looking. Daphnia are Planktonic Crustacean and belong to the class Branchiopoda. This class includes Fairy shrimp, Clam shrimp, Cladocera, and multiple other crustaceans (Ebert, 2005, pg.1). Even though, Daphnia are not very visible to the naked eye, and are very hard to find, Daphnia are …show more content…
But what about a drug that is perfectly legal and someone could take such a large dosage, that is easily enough to kill them. Caffeine needs to be regulated, not by parole department or government officials, but by the person who consumes. Like stated, in Newton's third law of motion, every action has an equal and opposite reaction. Meaning in a different sense than motion laws, if someone takes over dosage of caffeine, it may have positive effects like to stay awake in the morning, but it will also backfire on the body. Caffeine may be one the most common ingredients in candy and drinks, however it has many consequences that are both long term and short term to the

Daphnia Research Paper

Introduction Daphnia or "water fleas," are small aquatic crustaceans. They live in a variety of aquatic habitats, including freshwater lakes, streams, ponds, and rivers. These organisms are useful for biological research due to their important interactions within their ecological niche. An ecological niche is the role and position that a species occupies within its ecosystem. Daphnia has a myogenic heart which differs in structure from human hearts but shares similarities in the way it is controlled…

Daphnia Magna Research Paper

Daphnia magna are planktonic crustaceans that belong to the subclass Phyllopoda. They can dwell in a great margin of standing freshwater with an exception for extreme habitats (Ebert, 2005). Some species may be found clinging to substrates like water plants or over sediments of shallow ponds (Ebert, 2005). Daphnia magna adults can range in size from smaller than 1mm to as great as 5mm. Daphnia have open blood circulation, and their heart is located dorsally which is anterior from the brood chamber…

Daphnia Experiment: Crayfish Mortality

Discussion: Our principle prediction: Crayfish mortality will increase with increasing concentrations of oil (we predicted this because of what is seen with oil spills) Comparison to the Daphnia experiment What was different about our results and what was similar Comparing the water oil levels to other oil spills and the observed reactions (compared to ours and the articles that we found) Ex: Wyoming Wetlands Ex: Marshes in Louisiana Meaning of the study: most oil spills will lead to mortality…
