Answer:
The correct answer is carbohydrate chain.
Explanation:
Plasma membrane contain various proteins such as peripheral proteins,transmembrane proteins,GPI anchored proteins.Among them some protein contain carbohydrate chain basically oligosaccharide chain which is arranged in the extracellular portion of the plasma membrane.
The principle function of these oligosaccharide side chains is to detect various chemical and biochemical signals from outside the cell .
For example integrin is a glycoprotein that detect the signal for communicating with the adjacent cells.
Answer:
sodium is higher on the inside than on the outside, only free water molecules will be able to diffuse through the membrane. The water molecules will diffuse through osmosis from an area of low sodium conc. ... In doing so, the water itself is moving from high to low concentration.
I think the answer is Endospore. I'm sorry if I'm wrong...
Your answer is
