Life history and kidney function
Your lab partner is concerned the insectivores that you are studying seem to have an unusually active rate of kidney activity. What should you tell her?
Multiple Choice
The toxicity of the insect-based diet creates the necessity of removing toxins from the blood of the insectivores, so the kidneys must maintain high
rates of activity.
High rates of kidney activity are characteristic of aging animals, so you can infer that your insectivores are reaching the end of their life span.
Laboratory animals often have artificially high rates of kidney activity.
The high protein diet supplies a large amount of nitrogenous waste to be processed, so the kidneys must be very active to keep up.
