Answer: Oogenesis
Explanation:
Oogenesis is a process in female reproductive system in which a matured ovum is formed from egg cell.
In human reproductive system one mature ovum is produced from four haploid cells during meiosis. This ovum is very large and it unite with the sperm to produce zygote.
There are three stages of Oogenesis, the multiplication phase,the growth phase and maturation phase.
In the multiplication phase, the germinal cells divide to form oogonia. The oogonia multiply and form oocytes. The oocytes pass through the growth phase and mature to form ovum.
Answer:
In Metaphase of Mitosis, the chromosomes line up along the middle of the dividing cells

The answer is D. NADH to NAD+
When no oxygen is present, anaerobic respiration occurs.It is the only way to produce ATP in this condition.NAD+ is necessary because it is converted into NADH and at the same time ADP is converted to ATP in the reaction of pyruvate synthesis from glucose.Therefore, NADH must be converted to NAD+ in order to have NAD+ always present in the cell.
