Enzymes that move certain phospholipids between leaflets have also which of the following properties?
iren2701 [21]

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).

If no other changes occurred, how would emigration affect the population density of a group of organisms?​
valentinak56 [21]

<u>Answer:</u>

<em>If no other changes occurred emigration would have a negative impact on the population density of a group of organisms. </em>

<u>Explanation:</u>

<em>Emigration is the movement of a part of population out of an area into a new area. </em>It has a negative impact on the population of the old area and positive impact on the population of the new area.

Population density is the population per unit area that is population per square kilometer.

Thus population density will also be negatively affected by emigration. <em>Hence an area that previously was densely populated might become a sparsely populated area due to emigration.  </em>

Lunar eclipses are more visible because the Earth casts a bigger shadow on the Moon during a Lunar eclipes, but during a Solar eclipes the Moon casts a bigger shadow on Earth so its less visible.
