Answer:

A. play a role establishing and maintaining membrane lipid asymmetry

Explanation:

Proteins that move move certain phospholipids between leaflets are transmembrane proteins via "flip-flop" transition have also the possibility to maintain membrane lipid asymmetry. There are few types of such proteins:

  • flipases-move lipids from the exterior to the interior side of the membrane, energy required
  • flopases-move lipids in reverse comparing to flipases, energy required
  • scramblases-no energy required, bidirectional

Because of the action of those proteins, cytosolic side of plasma membrane differs from exoplasmic side (asymmetry).

In a healthy person, after a carbohydrate-rich meal, the production of the hormone ________ will increase, causing the uptake of
wel
 The answers are insulin?glucose. After a meal, the digestion of carbohydrates in the intestines release sugars , which are absorbed into the blood. If food contained high levels of simple sugars then blood sugars level rises quickly. Insulin is a hormone which is released by the pancrease in response to rising blood sugar levels. Insulin causes sugars to be stored in the liver in the form of glycogen and this in turn lowers your blood sugar level.

A population _____ follows a period of ______.
leva [86]

Answer:

The correct option is <em>A. decline, overshoot</em>

Explanation:

Carrying capacity can be described as the maximum number of a particular population size that an ecosystem can hold. The resources such as food, water, space etc are enough for a specific number of species. Sometimes, when a population diebacks, there are more number of resources present than the consumers, so the consumers start to reproduce and expand. The population of these organisms then might overshoot the carrying capacity.
