You need to put an image so I can describe it, put one and comment that you added it and I'll edit this with the answer
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).

Too Much Growth Hormone in a Child: Causes and Effects
Growth hormones are important influences on a child’s height and development. While many children are shorter or taller than others due to genetics, some children may have a growth disorder.
Growth disorders affect the speed at which a child develops. Height, weight, and sexual development are just a few features which can be affected. Diseases or problems with the pituitary gland are the leading causes of growth disorders.
The pituitary gland is responsible for producing growth hormones. Too few can lead to poor growth in children, while too many can lead to a condition called gigantism.
Answer:
The stem cells are the special cells that can develop into different types of specialized cells. There are two major stem cells in the body. The one is an embryonic stem cell that presents in the initial divided few cells that have the ability to develop into any type of specialized cells.
The other one is adult stem cells such as Bone marrow that contains two types of stem cells: hemopoietic which has the ability to produce all three types of cells, and stromal that able to produce special muscles and bones due to their limited ability to develop specialized cells or multipotent.
Thus, embryonic stem cells are more useful than adult stem cells.
Explanation:
viruses are very small -- 100 times smaller than the average bacterium, so small that they can't be seen with an ordinary microscope. Viruses can only exert influence by invading a cell, because they're not cellular structures. They lack the ability to replicate on their own, so viruses are merely tiny packets of DNA or RNA genes enfolded in a protein coating, on the hunt for a cell they can dominate.
