In response to a decrease in tissue metabolic activity, tissue oxygen concentrations ________, which causes a(n) ________. In response to a decrease in tissue metabolic activity, tissue oxygen concentrations ________, which causes a(n) ________. increase : active hyperemic response decrease : dilation of the arterioles decrease : increase in tissue ischemia decrease : active hyperemic response increase : constriction of the arterioles

Answers

Answer:

The correct answer is - increase: constriction of the arterioles.

Explanation:

When the physical activity is decreased by the tissues of the muscle, the oxygen concentration in the tissue increases which leads to the constriction of the arterioles.

It takes place in order to decrease blood flow and blood pressure as oxygen requirement is less in the tissue in decreased physical metabolic activity. The constriction of arterioles results in more resistance to decrease the blood flow in capillaries.

white sands national monument in New mexico has hundreds of miles of white sand dunes made of gypsum crystals. which of the following would you expect to be true of white sands national monument?
a. it receives no radiation
b. it is immune to insolation
c. it has a high albedo
d. it has no heat capacity

Answers

Gypsum, a soft mineral frequently left behind when water bodies evaporate, is what gives the sands of White Sands National Monument a high albedo their texture, hence option C is correct.

What is white sands national monument?

Despite being a very common mineral, gypsum is rarely found as sand because it readily dissolves in water and is often transported to the sea by rivers.  

The dunes seem white like snow additionally, gypsum doesn't absorb heat from the sun as silica sand does.

Therefore, gypsum is actually a transparent material, but due of the frequent collisions between the grains,, hence option C is correct.
