Answer:

germline mutation

Explanation:

It is germ line mutation which can be passed on from one generation to another that means from parents to off springs. The term germ relates to the one which is capable of germination i.e. reproduction.

There are two types of cells in our body (1) somatic cells (2) germ cells.

Germ cells are the cells which are produced in the primary sex organs like gonads.  Since gonads are responsible for producing gametes (ovum and sperms) which are capable of reproducing an entire organism after fertilization, they are regarded as germ cells. Somatic cells on the other hand are not responsible for fertilization. So, if a mutation occurs in germ cells which is known as germline mutation, it will pass on to the off spring while a mutation in somatic cells will be restricted to the individual without being passed on to the next generation.

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.

The picture represents gas exchange in the alveoli. Observe what is happening at location X.
aivan3 [116]

A

CO₂ is the waste product of respiration of cells. Oxygen, on the other hand, is required in cellular respiration. Therefore at the alveolar in the lungs of an organism, CO₂ will be expelled while O₂ will be taken in.

Explanation:

This occurs passively due to the diffusion gradient, CO₂ usually has a higher concentration in the blood and lower concentration in alveoli hence this gas diffuses from the bloodstream into the lungs. On the other hand, oxygen is higher in concentration in the alveoli than in the blood capillaries hence difuses into the blood and taken to the cell for respiration. The CO₂ in the lungs is then expelled through exhalation of the lungs.
