Problem:
Question 1: What is a feedback inhibition mechanism? Does the liver have one of these mechanisms for urea production?
Question 2: Using yourself as a model organism, describe in detail specific examples of mutualistic, parasitic, competitive and predatory interactions that you are directly or indirectly involved in. Be sure to indicate the positive aspect that was gained and the negative aspect (injury,stress,monetary, loss of time...) that was lost from each interaction.
Any help would be greatly appreciated!
