Which of the following is the process of meiosis for egg cell formation?
Ovaries
Oogenesis
Ovulation
Oocytes
The Correct Answer is B
a: Ovaries - The ovaries are the female reproductive organs where oogenesis occurs, but they are not the process itself.
b. Oogenesis: Oogenesis is the process by which female gametes (egg cells) are produced through meiosis in the ovaries.
c: Ovulation - Ovulation is the release of a mature egg from the ovary, not the process of egg cell formation.
d: Oocytes - Oocytes are immature egg cells found within the ovaries; they undergo oogenesis to mature into eggs.

Correct Answer is C
Explanation
a: Chest cavity compresses the lungs - This is incorrect; during inspiration, the chest cavity expands, not compresses.
b: Length of the thoracic cavity decreases - This is incorrect; during inspiration, the thoracic cavity increases in length as it expands.
c. Diameter of the thoracic cavity increases. When inspiratory muscles contract, such as the diaphragm and external intercostal muscles, the thoracic cavity expands, increasing its volume. This expansion decreases the pressure within the lungs, causing air to flow in (inspiration).
d: Diaphragm rises up in the abdomen - This is incorrect; during inspiration, the diaphragm contracts and moves downward, not upward.
Correct Answer is B
Explanation
a. Formation of polar bodies: Formation of polar bodies occurs only in oogenesis, not in spermatogenesis.
b. Meiosis: Correct. Both oogenesis and spermatogenesis involve meiosis, the process of cell division that reduces the chromosome number by half.
c. Development of a Graafian follicle: This is specific to oogenesis. The Graafian follicle is the mature ovarian follicle.
d. Fertilization: Fertilization is the union of sperm and egg, not a process that occurs during the development of either gamete.
