Biology: Dissection Essay, Research Paper
For my undertaking that I & # 8217 ; m making for biological science, I & # 8217 ; m making a dissection. I & # 8217 ; m traveling to be executing my undertaking with Trevor Johnson, Tyler McCaskill, and Tom Shudt.The dissection that we decided to make was the dissection of a male and female shark.
We are making a dissection on a shark because we want to larn about the shark anatomy and the manner the sharks organs work to maintain all the H2O out and still eat fish while they are swimming around in the ocean.We besides want to cognize how the sharks tegument is so immune to malignant neoplastic disease. We besides wanted to cognize a small spot about the shark, so possibly if we decide to travel into the field of Marine Biology we would hold a small more cognition on what the occupations in that field are like.I besides thought that it would be interesting to dee a shark up near and in individual because we either have to travel to the ocean or to an fish tank merely to see a shark.
When the word Shark comes to mind most people think of a monster that feeds on worlds and is an enemy of all living existences. Contrary to popular belief less than 10 per centum of sharks are known to assail worlds motiveless. Sharks are classified under the category of Chondrichthyes, which is fish that have features of a skeleton made of gristle, jaws, paired fives, and paired anterior nariss. The superorders are divided into two groups, which are Batoidea that have beams and their relations and Selachii, which are sharks. Scientists have found stray spinal columns, dentitions, and graduated tables that appeared 350 to 400 million old ages ago in the Devonian Period known as & # 8220 ; Age of Fishes & # 8221 ; . Most modern sharks have evolved 100 million old ages ago w
biddy dinosaurs lived on Earth. ( Matthews, 1989 ) Sharks have been known to populate tropical and temperate seas every bit good as some cold and polar seas. Migration of sharks is ill understood due to non all species migrating. And in the species that do migrate the distance may be short or long and is based on handiness of the nutrient and environmental rhythms. One American life scientist Eugenie Clark is the universe leader in shark survey, she was the first individual to larn how sharks behaved in imprisonment and how good sharks had the ability to understand. Through her surveies with lemon sharks she found out that sharks were able to larn indispensable things but when there was a drastic alteration in what they were use to sharks were non able to set. There is much scientific signifigance to my dissection ofj the great sand shark ( dog fish ) . “In the early 1950’s, Dr. John F. Prudden, discovered the effectivenss of shark gristle during his work on lesion healing and srthritis. In1972, Prudden injected gristle into a adult female who was being treated for cankerous chest cancer.Her malignant neoplastic disease wholly regressed.”

This is one inccident were the shark has been used to bring around malignant neoplastic disease. It turns out that the sharks skin doesn & # 8217 ; t assist better the paitient ; it & # 8217 ; s the gristle of the shark that help the malignant neoplastic disease patient and makes the sharks more immune to cancer.Bovine ( cow ) gristle works merely like the shark gristle to run off malignant neoplastic disease.
The sharks are the most deathly characters in the universe. They merely hurt you if you are shed blooding. My advice is that if you & # 8217 ; re of all time plunging in the ocean with your scuba cogwheel merely wear & # 8217 ; t cut yourself on a jaggy stone.
