Answer:
A. Renin levels increase with poor kidney perfusion
D. Nephrotoxic drugs are a cause of intrarenal failure.
Explanation:
Renin is produced in the kidney for angiotensin aldosterone hormonal system and it is helpful in maintaining the blood pressure and other metabolic activities. However when the renin level is high then it means the kidney has a perfusion issue .
Nephrons are kidney cells. When a drug which is toxic to them gets into the body system then it affects the kidney and may cause kidney failure.

The correct option is C.
Explanation:
Evolution refers to the gradual development of living organisms from earlier forms to the forms that exist today. One of the principal factors that lead to evolution is the ability of an organism to adapt to adverse changes in its environment. Organisms that are able to survive adverse changes in their environments usually go on to produce offspring that possess their parents' ability to survive. A good example of this is given in option C, where individuals with denser fur were able to survive from severe cold and then give birth to young ones that inherit their parents' ability to survive severe cold.
