Compare the number of eggs to the number of sperm that result from meiosis?
Molodets [167]

Answer:

In the result of meiosis, testes produce 4 small mature sperm while ovaries produce 1 large egg cell.

Explanation:

Meiosis produces gametes (sex cells). Sex cells are eggs in females and sperm in males.

In the female, ovaries produce four haploids (3 polar bodies and 1 immature egg) under meiotic division. Polar bodies die because of the unequal division of cytoplasm. The immature egg matures into a large ovum/egg every 28 days during the menstrual cycle that is able to fertilize.

In the male, meiosis occurs in testes that produce 4 spermatids that mature into 4 small sperms. Testes produce several hundred million sperms every day under meiosis. These sperms are able to fertilize.

Nevertheless, if we want to compare their numbers based on meiotic division, we would say that they will be in the same ratio (1:1) at the end of each meiosis cycle for males and females.

Obviously, Deneb is intrinsically very bright to make this list from its greater distance. Rigel, of nearly the same absolute magnitude, but closer, stands even higher in the list.

The lungs are perfused by two circulations: the pulmonary and the bronchial. The pulmonary circulation is for oxygenation of blo
WINSTONCH [101]

Answer:

True

Explanation:

Pulmonary circulation transports blood through the alveoli for gas exchange. In this circulation the blood that comes from the veins initially has low oxygenation, and then leaves the right ventricle of the heart through the pulmonary artery, enters the lungs and returns to the heart with arterial and oxygenated blood

The bronchial circulation is well oxygenated and provides oxygen to the lungs. The structures to which this oxygen contributes in lungs are those that do not participate in a gas exchange.
