Answer: option D - After eating a large batch of salty popcorn, levels of salt in the urine increase

Explanation:

Homeostasis is the ability of a living organism to ADJUST its internal environment to maintain a stable equilibrium

FOR EXAMPLE: warm-blooded animals like humans allow blood vessels dilate during hot weather, and constrict during cold weather IN ORDER to maintain a constant body temperature.

Thus, after eating a large batch of salty popcorn, levels of salt in the urine increase due to the homeostatic mechanism of the ANTI-DIURETIC HORMONE stimulating reabsorbtion of water from urine, and excretion of excess salt.

The situation that best represents a homeostatic mechanism is the increased salt level in urine after eating a large batch of salty popcorn.

Homeostasis

It is the maintenance of relatively constant internal processes.

The normal operating range of processes isreferred to as setpoints.

Breaching of setpoints may cause irreversible damage to organisms.

Too much salt in the system is an example of a breached setpoint.

The body system will respond appropriately in order to get rid of excess salt and return the system back to normal salt concentration.
