<h2>Answer </h2>
Neutral Variation
<u>Explanation</u>
Point mutations in noncoding regions of DNA result in neutral variation. The alleles which neither considerably sum to nor exceedingly lower from body consistency. It is the accumulation of such alleles located within a community that can be explained as expressing neutral variation. Neutral Variation implies in various alleles that are existing at an assigned genetic locus because those alleles are not distinct by natural selection.

What is the real meaning of this questions
Answer;
One can infer that membrane transport proteins are required in order for neurons to fire.
Explanation;
Transport proteins are proteins that transport substances across biological membranes. Transport proteins are found within the membrane itself, where they form a channel, or a carrying mechanism, to allow their substrate to pass from one side to the other.
-Transport proteins transport materials such as; ions such as sodium and potassium; sugars such as glucose; proteins and messenger molecules; and many more. In neurons, they play a fundamental role in the functioning of nerve cells. These transporters, a third class of membrane transport proteins, move a wide variety of ions and molecules across cell membranes.
B. New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken.
Explanation:
The correct statement from the given choices is that new compounds with lower-energy bonds must be formed when the high- energy bonds in the food molecules are broken down.
Cellular respiration is classified as an catabolic process in which an energy rich substance is broken down into a lesser one.
- Metabolic processes are usually divided into catabolic and anabolic processes.
- In catabolic step, energy is broken down.
- Cellular respiration is catabolic whereas photosynthesis is anabolic.
- The new compounds formed have lower energy bonds after respiration.

<h2>Answer:</h2>
The correct answer is option D which is bones provide structure and support to the body, while muscles move the bones.
<h3>
Explanation:</h3>
- The muscles are composed of muscle cells, 3 layers of connective tissues are also associated with muscles.
- Muscles are soft tissues of body which have ability to contract and relax.
- Bones are hard tissues composed of collagen fibers and inorganic minerals. Muscles are attached with bones. Due to hard structure, bones provides support and structure to body. While muscles are attached with bones, and their contraction and relaxation is the cause of movement
