Cells lining kidney tubules function in the reabsorption of water from urine. in response to chemical signals, they reversibly insert additional aquaporins into their plasma membranes. in which of these situations would your tubule cells have the most aquaporins:

(a)-after a long run on a hot day,

(b)-right after a large meal,

(c)- after drinking a large bottle of water

(c)- after drinking a large bottle of water

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
