pochemuha

Ans.

In humans, there are total of 46 chromosomes in each cell that show 23 pairs of chromosome. During reproduction, meiosis occurs in germ cells that leads to formation of daughter cells or gametes that contain half of the chromosomes as present in parent cells. Thus, each gamete (either male or female) contains 23 chromosome.

During fertilization, fusion of male gamete or sperm(with 23 chromosomes) and female gamete or ovum(with 23 chromosomes) to form zygote that develops into multi-cellular offspring with 46 chromosomes.

Thus, 'a child inherit 46 chromosomes from his or her parent (23 chromosomes from each parent).'

When neurons "fire," the first thing that happens is that sodium ions enter the cell. this does not require an input of energy.
Karo-lina-s [1.5K]

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.
