A.

false

B.

true

Answer and Explanation

The Correct Answer is A

Cleavage is a series of rapid mitotic divisions of a fertilized egg (zygote) that results in daughter cells (blastomeres) with the same number of chromosomes as the parent cell. However, if the context was about meiosis, then the statement would be accurate. Since the question does not specify meiosis, this is true for cleavage in general.

Explanation

A. Cutaneous transpiration: While cutaneous transpiration (evaporation of sweat from the skin) contributes to water loss, it is not the primary mechanism controlling water output.

B. Drinking: Drinking affects water intake rather than output. It does not directly control how much water is excreted from the body.

C. Urine volume: Urine volume is the primary means by which the body regulates water output. The kidneys adjust urine volume to maintain fluid balance and homeostasis.

D. Sweating: Sweating contributes to water loss but is not the primary mechanism for controlling overall water output compared to urine production.
