In sexually reproducing species, males produce sperm and females produce eggs.

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.

A. Uterine tube: Fertilization typically occurs in the uterine tube (also known as the fallopian tube). The sperm travels from the cervix through the uterus and into the uterine tube, where it meets and fertilizes the egg.

B. Uterus: The uterus is where the fertilized egg implants and develops into a fetus, but it is not where fertilization occurs.

C. Ovary: The ovary is where eggs are produced and released during ovulation, but fertilization does not occur here.

D. Urinary bladder: The urinary bladder is part of the urinary system, not the reproductive system, and has no role in fertilization.
