Answer:

c) Contaminated food

Explanation:

Protozoans are single-celled organisms that could be either free-living or parasitic. Free-living forms could inhabit in the soil, moss, and even in aquatic environments. On the other hand, parasitic protozoans need a host to develop and reproduce.

A protozoan gastrointestinal infection could be <u>caused by the ingestion of cysts through contaminated food</u>. For instance, giardiasis could be spread through the ingestion of contaminated food or water or directly from person to person. Amoebiasis is also an example of a gastrointestinal infection caused by the protozoan <em>Entamoeba histolytica, </em>which occurs through the ingestion of  food that is contaminated with animals' feces, this occurs especially in developing countries.

Olympic athletes train in Colorado Springs, Colorado because this location is at high altitude and near the 14,000 foot Pikes Pe
Stels [109]

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.
