Answer:

Fission Hypothesis

Explanation:

This theory proposes that the Moon was once part of the Earth and somehow separated from the Earth early in the history of the solar system. The present Pacific Ocean basin is the most popular site for the part of the Earth from which the Moon came.

This theory was thought possible since the Moon's composition resembles that of the Earth's mantle and a rapidly spinning Earth could have cast off the Moon from its outer layers.

However, the present-day Earth-Moon system should contain "fossil evidence" of this rapid spin and it does not. Also, this hypothesis does not have a natural explanation for the extra baking the lunar material has received

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.
