ANSWER 24- OPTION B high osmolarity; increased blood volume

EXPLANATION- RAAS is secreted when there is low blood pressure and in cases of low osmolarity where there is low blood volume and thus RAAS increases the pressure of blood by increasing the reabsorpion of the fuids thus improving the blood volume.

ANSWER 32- OPTION A  decrease temperature for sperm production

EXPLANATION- sperms are produced at a temperature lower than that of the body's, so having then housed in the sac ball outside of the body gives them the optimal conditions for sperm production and storage.
