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.

Cloud [144]

Answer:

C. Both A and B describe errors in the statement.

Explanation:

In fossilization i.e formation of fossils, two terms are used as follows: permineralization and petrification.

- Permineralization is a process whereby the pore spaces of an organism's remains are filled with mineral matter that precipitates from lake and ocean solutions.

- On the contrary, petrifaction or petrification is the process whereby a once-living tissue (matter) are REPLACED by minerals, hence, preserving the organism's structure by turning it into a stone (petros).

According to this question, the student mixed up their definitions by giving the definition of permineralization instead, however, options A and B have described the errors associated with the statement.

I believe that a diet high in fat and meat is linked to high rates of colon and prostrate cancer. Cancer is the abnormal and uncontrolled cellular proliferation. Prostrate cancer is the common cause of cancer in men and may be detected by rectal examination, PSA blood test, ultrasound, and biopsy. Colon cancer is the cancer of the large intestines which is the last part of the Gastrointestinal tract.
