The pharynx would need to come first in order for C to be correct.
B is also incorrect. Air flows through the bronchioles, then the
alveoli, and finally into or out of the capillaries where gas exchange
can occur with cells.
A is the only option that correctly describes the path of air through the respiratory system in the correct sequence.
The complete flow of air would be:
Nose>pharynx>trachea>bronchi>bronchioles>alveoli>gas
exchange with cells and then back out.
Answer:
a. Liver cell
Explanation:
Meiosis is a reductional division that produces haploid cells from diploid existing cells. Male and female gametes such as sperms and egg cells are haploid. Sperms are produced by meiosis in spermatogonia. The egg cell is produced by meiosis in oogonium. The liver cell is a diploid cell and is produced by mitosis. Mitosis maintains the DNA content and genetic information of the parent cells into the daughter cells.
