Answer:

Oocyte refers to the female germ cell which is involved in the process of reproduction.

In humans, the primary oocyte is diploid in nature, that is, it contains 46 chromosomes as it is formed by mitotic divisions of the oogonium.

In contrast, secondary oocyte is haploid in nature, that is, it contains only 23 chromosomes as it is formed from primary oocyte after it has completed its meiosis I.

Secondary oocyte then undergoes meiosis II to produce a mature ovum.

<span>About the conservation of energy. Suppose you are in a vacuum and you bunch a basketball. You will notice that no matter how much you will leave the ball bunching the ball will never stop. That happens because the ball develops both potential and kinetic energy, the sum of those two give us the mechanical energy which remains constant. We have to suppose that friction is zero otherwise you have to count for thermal loses. </span>I hope that this is the answer that you were looking for and it has helped you.

The domestic cat genome contains 2.9×109 base pairs. The length of linker DNA in mammals is 50 base pairs. Approximately how man

IgorLugansk [536]

Answer:

Number of nucleosomes in $2.9 * 10^9$ bp is equal to $1.47 * 10^7$

Explanation:

For wounding one nucleosome, total length of DNA required is equal to $146$ bp

The length of linker DNA in mammals is equal to $50$ bp

Thus , the total length of DNA that confides between two nucleosome is equal to the sum of wounding length of DNA and the linker length

$= 146 + 50\\= 196$ bp

Thus, in $196$ bp length of DNA, the total number of nucleosomes is equal to $1$

Thus, number of nucleosomes in $2.9 * 10^9$ bp is equal to

$\frac{2.9* 10^9}{196} \\1.47 * 10^7$
