Answer:
A
Explanation:
Mountains are usually formed at what are called convergent plate boundaries, meaning a boundary at which two plates are moving towards one another.
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.
Answer:
I think it would be grass.
Explanation:
I am pretty sure it would be grass because there is much more grass on earth then hawks, snakes, and rabbits.
Answer:
I think the answer is B.
Explanation:
I think this because they have these variations to better adapt to conditions in their environments.
