Answer #1

A vertebrate skeleton is consists of bones and skeletal muscle. The skeleton system provides support and maintains the posture of the body. It also transfers the muscle force during movement body. Bone sin skeleton system stores excess calcium and releases it in the need for body, thereby maintaining calcium homeostasis.

The answer is E.

2. The excess of water is released as urine by the action of inhibition of anti-diuretic hormone, so that kidney absorbs less water and forms more urine.

The aquaporins help in water reabsorption so less urine is produced, bu due to less aquaporin, reabsorption decreases, and urine volume increases.

The answer is E.
