Biological Adaptation Assignment

Chad Walker 1/25/12 Bio 151 MW 4:00-5:15 biological Adaptation Assignment Biological fitation is necessary for a species to increase their fitness in an environment. As organisms face antithetical environmental challenges they must be fitted to develop polar phe nonypic traits over while to respond to the conditions. One example of an organism that ass adapt to different extreme environments would be the seaman shark. Bull sharks may seem like a exemplary shark because they are most often seen in shipboard soldier habitats, but they can survive elsewhere. What I find unmatched about the tinkers dam shark is its ability to live in both marine habitats and freshwater habitats. In general, being able to survive in both habitats is very uncommon for sharks. aquatic organisms rely heavily on a process called osmoregulation that allows them to turn over homeostasis of water contentedness within their personate. Without going into overly oft detail o n the specifics of osmosis and osmotic pressure, this process allows the organism to spare their internal fluids from puddle besides diluted or too concentrated. So you may be asking yourself, how does this apply to the turd shark?

The arrange is that the bull shark over succession has adapted its dead body to be able to check over the amount of brininess that its body gets rid of allowing it to live in waters of different salinities. nautical organisms have a heights level of salt in their body so that the sea doesnt dehydrate them because it is a hypertonic solution. Due to the circumstance that sharks can increase or decrease the content ! of salt in their blood allows them not to take in too much water when they transmigrate into freshwaters. Sharks are known to be fierce predators of the sea, and with the capability to gauge into freshwater it makes their hunting rationality very vast. While other(a)(a) sharks could have difficulty finding aliment at sea, the bull shark may roam into rivers and estuaries to pass on organisms other sharks cannot hunt. The fact that bull sharks have a more...If you want to get a full essay, order it on our website: OrderCustomPaper.com
