Answer: Haploid number
In normal humans, sex cells contain the diploid number of chromosomes
Explanation;
Human somatic cells or body cells are diploid such that they contain two sets of 23 chromosomes which gives a total of 23 chromosomes. Examples of somatic cells in the body that are diploid include, epithelial cells, somatic cells, liver cells, blood cells, nerve cells, etc.
However, mature sex cells are haploid, which means they have one set of 23 chromosomes which means they have 23 chromosomes. Sex cells are the results of meiosis type of cell division in which a diploid cell divides to form four daughter cells that are haploid.
So he doesn't fall and drown
The answer is all of the above
Oogenesis and spermatogenesis both involve the chromosomal-reduction divisions of meiosis,which takes the gametes from the full complement of chromosomes to the Haploid number of chromosomes. Meiosis is the type of cell division that take place in the gamete cells, where diploid cells of the germ lines undergo cell division to yield haploid cells, normally the gametes are made through this process, that is, the ovum through Oogenesis, and the sperm through spermatogenesis. During fertilization the two combines to produce a diploid cell once again that undergoes continuous mitosis to form a zygote.
Answer:
The function of pulmonary ventilation is to b. maintain adequate alveolar ventilation.
Explanation:
<em>Pulmonary ventilation refers to the movement of air into and out of the lungs, so its main function is to maintain adequate alveolar ventilation.</em> The air moves out of the lungs when the pressure inside the lungs is greater than the pressure in the atmosphere. In the lungs, Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. That's how the oxygen gets into the bloodstream.
