As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria.

C. depth C

Explanation:

n200080 [17]

Answer:

a) 3 cromosomes b)3

Explanation:

The haploid number of a cromosome is the total number ofcromosomes withoutits homologue partner. In this case, if the text indicates that the haploid number of cromosomes is 6, then that is the total number of cromosomes in the result cell.

The ovum contains just half of the information that will be given in order to form the new organisms, in this context, if the result organism has  cromosomes, the ovum will only contain 3.

In meiosis II, after both cigotes get together and unite all the 6 cromosomes, it separates again. This means that the second polar body will remain will only 3 cromosomes again.
