Cell at metaphase of mitosis contains 20 sister chromatids, how many chromosomes will be present in a g1 cell? if a cell at meta
kumpel [21]

Answer:

The correct answer would be 10.

The cell cycle can be divided into four phases namely gap 1 (G₁) phase , synthesis (S) phase, gap 2 (G₂) phase, and  mitosis (M) phase.

DNA (deoxyribonuceic acid) content is only replicated and doubled in the S phase. However, the chromosome number remains the same. It can be explained as the number of chromosomes remains the same (2n) but number of chromatids doubles (4n) after S phase.

The number of chromatids restores to 2n in daughter cells after completion of mitosis.

Hence, if number of chromatids in metaphase was 20 i.e. 4n then the number of chromosomes (2n) would be 10.

Hence, 10 chromosomes or 5 pairs of chromosome would be present in the cell during its G₁ phase.

qaws [65]

Answer:

Lateral Hypothalamus

Explanation:

According to the hunger researchers' initial assumption lateral hypothalamus is that part of the brain which regulates intake of food and metabolical activities like metabolical regulation of peptides like  the orexins melanin-concentrating hormone. It is that part of the brain that plays a key role in the ingestive behavior regulation.

The lateral hypothalamus system initiates physical and cognitive processes like it promotes arousal and feeding behavior, metabolism, regulates body temperature, BP, etc. and when stimulated it results in the feeding behaviour in animals as they begin to eat.
