At which time after clear-cutting does this exhibit the greatest species richness?    

A person trying to pass a law against texting while driving says, “Everyone agrees that this is a bad thing, so we should make it a crime.” Which perspective on crime does this person most likely support?

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!)

Which of the answers best describes passive natural immunity?

Explain the following: If both voltage-gated Na+ and K+ channels are stimulated to open by depolarization to threshold, why does the membrane depolarize further (beyond threshold to +30mV) and not simply remain stable/unchanged?

An elevated neutrophil count could indicate

Explain the process of neurotransmitter secretion. Include all events, channels and ions involved.
