The order which reflect clomiphene's mechanism of action include the following:
- Secretion of increased amount of follicle stimulating hormone (FSH) and LH (luteinizing hormone).
- Growth of the ovarian follicle.
- Ovulation.
<h3>What is Ovulation?</h3>
This is the process in which a mature egg is released from the ovary and clomiphene is a medication which induces it.
This is done by the steps mentioned above so as to ensure mature egg is released for fertilization.

Answer: The bond between boron and hydrogen in boron trihydride is covalent bond.
Explanation:
The type of bonding between the atoms forming a compound is determined by using the electronegativity difference between the atoms. According to the pauling's electronegativity rule:
- If
, then the bond is non-polar. - If
, then the bond will be covalent. - If
, then the bond will be ionic.
We are given:
Electronegativity for boron = 2.0
Electronegativity for hydrogen = 2.1
As, 
is less than 1.7 and not equal to 0. Hence, the bond between boron and hydrogen is covalent bond.
The reasonable ground-state electron configuration is: 1s2 2s2 2p6 3s2 3p6 4s2 4d8
Answer:
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
