<h2>Ovulation</h2>
Explanation:
Women are born with approximately one to two million ova while female fetuses actually have far more egg cells when they are in the mother’s womb—sometimes as many as six or seven million eggs
- When egg cells are immature they are referred to as oocytes
- By the time a woman reaches puberty, there are only a small fraction of oocytes left—usually about 300,000
- During the reproductive lifespan, only about 500 of a woman’s eggs are ovulated
- The remaining eggs that are left behind die out during menopause
- Egg death is a natural part of the cycle of the female reproductive system so prior to menopause, women typically lose a thousand or so eggs every month
The flow of energy from the Earth's interior originates from two main sources: the radiogenic and primordial heat respectively. Radiogenic heat is produced by the radioactive decay of isotopes in the mantle, whereas primordial heat is the energy left over since the Earth's formation.
Without using any sensitive scientific equipment, this flow of energy is observable at stress points between the tectonic plates, such as volcanoes. These are ruptures in the crust of the planet through which materials from the interior of the planet are expelled.

Answer: DNA
Explanation:
A chromosome is a thread-like material with a long structure found in the cell nucleus. It mainly contains DNA and proteins. Due to the presence of DNA in chromosomes, it carries several genes.
The total number of chromosomes in human cell is 46: 44 are non-sex chromosomes while 2 are sex chromosomes
