Which of the following situations best represents a homeostatic mechanism? A) A person who becomes very nervous begins to sweat
Arada [10]

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.

Describe how surface currents would be affected if earth did not rotate
Tanya [424]
<span>When the earth spins in a certain direction, the ocean currents move in the opposite direction, sort of like when a car moves forward you are pulled backwards. However, there would still be wind and the gravitational pull of the moon which causes currents. The rotation of the earth just sort of "accents" these. So as a result, you would have many more smaller ocean current cycles.

A heater provides heat to an area, but the temperature in the area stays about the same. What do you already know about this phe
Oliga [24]

ANSWER: IT'S CALLED THE ZEROTH LAW OF THERMODYNAMICS

EXPLANATION:

The zeroth law of thermodynamics state that there's no heat transferred between two objects in thermal equilibrium (i.e having the same temperature). This phenomenon depicts that there's balance in the amount of temperature in all the three entities.

This phenomenon was credited to Sir Ralph Howard Fowler, a British physicist and astronomer during his lifetime.

A scientific paper by Carathéodory also added that when two systems S1 and S2 are made to reach equilibrium with a third system S3 under close thermal conditions, systems S1 and S2 are said to be in mutual equilibrium.
