It serves as a base and gains a proton, which charges it positively.
What is amino acid?
Proteins are made up of substances called amino acids. Proteins and amino acids are the components of life. Amino acids are the byproducts of the digestion or breakdown of proteins. Amino acids are used by the body to create proteins that aid in the digestion of meals.
Organic substances known as amino acids have both an amino and a carboxyl group. They can be differentiated by the functional group R that is attached. Six of the twenty amino acids that make up proteins have R-groups that are either bases or acids.

<span>Muscle tone that is abnormally high and that increases during activity is characteristic of MUSCLE HYPERTROPHY. Muscle hypertrophy occurs when muscles develop micro-tears within the tissues. As these micro-tears develop, they become scar tissues that make-up muscles into the strong and sturdy characteristics that they have.</span>
The answer for this question is a. DNA
Ok, I'm not 100% sure this is correct, given the context of the situation, but basically, the cell membrane helps the cell maintain homeostasis by keeping what needs to be in in & what needs to be out out. If it weren't for the cell membrane having the structure it does, all kinds of things could get into the cell & completely kill it from filling it with too much stuff, or the wrong things could get in (say, things with a really odd pH) & damage it badly. Or, it could let things get out extremely easily, such as enzymes and ions the cell needs to function properly.
Hope this helps!
E) Energy Pyramid
Technically it's an ecological pyramid, but E seems to be the closest to that.
