A cell surface protein is a proteins that is embedded in or span the layer of cell membranes of more complex organisms. These proteins are integral to the way in which a cell interacts with the environment around it, including other cells.
Answer:
one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
(B)
Explanation:
I don't know if this is correct but I think A <span />
The fluid-mosaic model describes the plasma membrane of
animal cells. The plasma membrane that surrounds these cells has two
layers (a bilayer) of phospholipids (fats with phosphorous
attached), which at body temperature are like vegetable oil (fluid).
And the structure of the plasma membrane supports the old saying, “Oil
and water don’t mix.”
Each phospholipid molecule has a head that is attracted to water (hydrophilic: hydro = water; philic = loving) and a tail that repels water (hydrophobic: hydro = water; phobic
= fearing). Both layers of the plasma membrane have the hydrophilic
heads pointing toward the outside; the hydrophobic tails form the inside
of the bilayer.
Because cells reside in a watery solution (extracellular
fluid), and they contain a watery solution inside of them (cytoplasm),
the plasma membrane forms a circle around each cell so that the
water-loving heads are in contact with the fluid, and the water-fearing
tails are protected on the inside.
