8 0

Answer: Somatic nervous system  

Explanation:

The voluntary nervous system or somatic nervous system the part of the PNS (peripheral nervous system) which is associated with the voluntary control of the body movements.

These movements are generally controlled by the skeletal muscles. It helps in various movements such as walking, bending, sitting, et cetera.

This nervous system consists of the efferent nerves and afferent nerves or we can say motor nerves that helps in controlling the movement of the body.

Deoxyribose Glucose Guanine Phosphate Ribose
Sergeu [11.5K]
There is no attached table, so it could not be told precisely which of the four molecules is the DNA. But, it is known that DNA consists of deoxyribose, guanine, and phosphate. 
The base unit of DNA is called a nucleotide. The nucleotide consists of a nucleobase (adenine - A, thymine - T, cytosine - C, and <u>guanine -G</u>), a monosaccharide <u>deoxyribose</u>, and a <u>phosphate </u>group. <span>By knowing this, it is easy to choose which molecule of those is the DNA.</span>

In which type of human cell(s) would 46 chromosomes be located? Select all that apply.A. diploidB. eggC. somaticD. gameteE. sper
Marrrta [24]

Answer:

A. diploid and C. somatic

Explanation:

Humans are diploid organisms and have 23 pair of chromosomes i.e. in total humans have 46 chromosomes.

There are 2 types of cells in humans (1) somatic cells and (2) germ cells.

Somatic cells are normal body cells which are diploid and have all 23 pairs of chromosomes. But, germ cells are special type of cells which are produced by gonads (sex organs). Germ cells are also known as gametes. In females, ovary is the sex organ which produces germ cells named as egg cells while in males testes is the sex organ which produces germ cells named as sperms. Germ cells (egg and sperm) are haploid cells which fuse to form a zygote which is the first cell of next generation. The process of fusion of egg and sperm is known as fertilization which is responsible for restoring diploidy in the progeny which receives half the genetic material from female parent and half the genetic material from male parent.

Suppose that an arginine residue in the active site of an enzyme was mutated to alanine. As expected, the alanine mutant was ina
Makovka662 [10]

Answer:

Alanine to lysine.

Explanation:

Mutation may be defined as the sudden, heritable change in the genome sequence of an organism. Two main types of mutation are chromosomal mutation and point mutation.

The mutation has occurred in which the arginine is replaced by alanine. The mutation that can restore to wild type is the conversion of alanine with lysine.    Since both arginine and lysine are basic amino acids. They both shows almost similar function and the replacement of lysine with alanine shows the wild type activity.

Thus, the answer is alanine to lysine.

What subatomic particle is transferred to the electron transport system from the krebs cycle?
mario62 [17]
<span>Electrons are transferred via Hydrogen atoms bound to NAD (nicotinamide adenine dinucleotide). Essentially, the krebs cycle harvests electrons (Hydrogen atoms) from pyruvates in the inter-membrane space via NADH and these feed into the electron transport chain to power ATP synthase to generate ATP.</span>
