Answer:
A: Oxygen levels are low and, therefore, more red blood cells are produced, giving the athletes an advantage when competing at lower altitudes.
Explanation:
<em>At high altitudes, the partial pressure of oxygen is lower compared to lower altitudes</em>. The body system try to adjust to lower oxygen level by undergoing several physiological changes. Depending on the duration spent in high altitude, the body can either try to adjust in the short term or acclimatize for a longer term.
One of the processes the body undergoes during acclimatization is an increase in red blood cell production. The kidney secretes erythropotein in response to inadequate oxygen in body tissues, and this makes the liver to increase erythrocyte production.
The increase in red blood cell production correspondingly increases the oxygen-carrying capacity of the blood as a result of increased hemoglobin. This condition persists for a few weeks even after the body returns to lower altitude where oxygen is adequate. Increased oxygen capacity means the rate of energy production (through respiration) within the body will also increase
<em>Hence, those who acclimatize to high altitude usually experience increased capillary density, tissue perfusion and improved athletic performance at lower altitudes. </em>
The correct option is A.
A tide just after the first or third quarters of the moon when there is least difference between high and low water
Answer:
Both male and female gametes are created during the process of meiosis. The formation of male gametes or sperm is called spermatogenesis. After telophase II of spermatogenesis, there would be <u>four</u> male gametes created that are all genetically <u>haploid.</u>
Explanation:
Telophase II is the final step in Meiosis II. In Telophase II of the spermatogenesis chromosomes travels to opposite poles and are covered by a nuclear envelop. The two parent cells result four daughter cells which are haploid (1n).
