Extra Credit (5 Points): One morning while swimming in the Gulf of Mexico, Alphonso swims directly into the path of an evil sea monster, which bites off part of his left arm. The resulting blood loss sends Alphonso into shock by the time he is rescued. His symptoms include paleness, cool skin, tachycardia, and a weak pulse. Explain each of these symptoms in detail using correct physiological terminology.  Your answer should explain how and why they have occurred based on the body’s responses to this type of crisis.  You should summarize the short-term and long-term responses based on what you learned in Chapter 20 about blood pressure regulation.

Explain the process of neurotransmitter recycling. What happens next to a neurotransmitter that has been secreted and bound to a receptor on the post-synaptic membrane (so, it’s already “done its job,” then what?)? You do not need to explain the post-synaptic responses here. DO use a specific example of a neurotransmitter in your answer.

The common chimpanzee (Pan troglodytes) and humans (Homo sapiens) began evolving separately from a common ancestor about 3.5 to 4 million years ago. The chimps evolved in the dense rainforest of the Congo Basin in central Africa, while humans evolved in the dry grasslands of east Africa with the Great East African Rift Valley in between. This is an example of  ____________ speciation caused by ____________ tectonic plates…

Specialist species can evolve on islands due to the limited availability of habitats and niches.  Based on the theory of island biogeography, which of the following islands would most likely experience the greatest decline in specialist species due to the possible immigration of a generalist species of the same trophic level as the various specialist species?  (toughie!)
