1. Explain in your own words why regulation is important. I would like you to use 2 examples, one from human communities and one from the human body in your explanation. Make sure to include how regulation is enabled in each case (i.e. how is communication occurring?).
2. In order for an effector to respond to a command via either of the endocrine or nervous system, it must be able to respond to a chemical (hormone or neurotransmitter). Explain how the effector is able to respond to these chemical signals (i.e. what must it have either in its membrane or inside its cells). Describe how this process of intercellular communication exemplifies the relationship between structure and function.

I have asked this question before however I am not getting the right answer. What is the evolutionary advantage to having the conduction velocity of neural impulses change with temperature, and which of the five major groups of vertebrate organisms might benefit most from this phenomenon? Explain thoroughly please.
