To protect the endangered species, some leatherback sea turtles are introduced into a protected ecosystem. The following function models the population of leatherback sea turtles, P as a function of the time, t in years, since they are introduced in the protected ecosystem P(t)=50+16t/2+0.1t https://i.gyazo.com/6e841f27ba9baa591cedde57db932a8f.png a.

Name: 18. In the northern Pacific Ocean sea otters feed on sea urchins and on starfish. sea urchins Teed on kelp and starfish feed on mussels. Beginning in the 1700s, sea otters were hunted for theirfur and driven nearly to extinction in some areas, resulting in trophic cascades in their communities. When the fur trade ended, sea otter numbers increased and their communities began to recover. One would expect that this recovery would result in...

will competition with a native mosquito species prevent the
spread of an introduced mosquito?
Ni=ki -a N2: Egn. 14.2 N2 = K2-B No : Egn. 14.3 Will Competition with a Native Mosquite Species Prevent the Spread of an Introduced Mosquito? Suppose the researchers want to use the data collected from their experiments on the competition between the non-native mosquito Aedes albopictus and the native mosquito 1. triseriars to better control the population of the non-native species. Suppose the researchers decide...

A seal swimming directly below the sea bird also simultaneously hears the sound. What is the distance below the sea that the seal can be found? a. 450m b. 67m c. 105m d. 2.98m e. 0.0436m
Based on mark/recapture studies between 2001 and 2006, the Southern Beaufort Sea 2006 population of polar bears is approximately 1526 bears. Suppose that since 2006 the population is being renewed at a rate of r(t) = 0.180 + 0.012t thousand bears per year and that the survival rate is 89%, where t = 0 corresponds to 2006.† (a) How many of the 2006 population of 1526 polar bears will still be alive 27 years from then? (Round your answer to...
