How long can hermit crabs go without food and water?
Sedbober [7]

They do eat but very little and can go several days up to two weeks without food. They store water in the back of their shell for moisture for their gills.

Which 28-day regimen is least likely to simulate ovarian production of estrogens and progestins?
lianna [129]

Answer:

The answer is A.

Explanation:

The question is incomplete, here is the full question:

The nurse is aware that which 28-day regimen is least likely to simulate ovarian production of estrogens and progestins?

A. Monophasic

B. Biphasic

C. Triphasic

D. Quadriphasic

The goal is to choose the regimen that causes the least stimulation of the ovarian production of the hormones estrogen and progestin and therefore used to prevent pregnancy.

Keeping the estrogen and progestin levels in the body can be done best by following the monophasic regimen which can be described as taking pills that have the same amounts of both hormones.

I hope this answer helps.
