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 diametric environmental challenges they must be fit 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 wrinkle shark. Bull sharks may seem like a typical shark because they are most often seen in leatherneck habitats, but they can survive elsewhere. What I find left(p) 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 accomplish homeostasis of water contentedness within their personate. Without going into as well as more detail on the sp ecifics of osmosis and osmotic pressure, this process allows the organism to handgrip their internal fluids from puddle also diluted or too concentrated. So you may be asking yourself, how does this apply to the dickhead shark?

The arrange is that the bull shark over time has adapted its dead body to be able to construe the amount of flavour that its body gets rid of allowing it to live in waters of different salinities. nautical organisms have a richly level of salt in their body so that the ocean doesnt dehydrate them because it is a hypertonic solution. Due to the accompaniment 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 railway yard very vast. While other(a)(a) sharks could have difficulty finding nutriment at sea, the bull shark may roam into rivers and estuaries to fodder 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
