What three principles is gas exchange based on in the respiratory system?

Answers

Answer: Ventilation, diffusion, and perfusion

Explanation:

Final answer:

The three key principles based on which gas exchange happens in the respiratory system are: partial pressure difference, large surface area for exchange, and effective transportation of gases.

Explanation:

The respiratory system relies on three main principles for gas exchange:

  1. Partial pressure difference: The exchange of gases (oxygen and carbon dioxide) in the lungs happens according to the differences in partial pressures. Oxygen moves from areas of higher to lower partial pressure, enabling it to enter the bloodstream where its pressure is lower.
  2. Surface area for exchange: The structure of the lung surface, specifically the alveoli, provides a large surface area for effective gas exchange.
  3. Transport of gases: Gases like oxygen and carbon dioxide are carried in the bloodstream. Oxygen is primarily carried attached to hemoglobin in red blood cells, while carbon dioxide is primarily transported in plasma as bicarbonate ions.

Explain why genetic diversity is necessary in order for natural selection to occur

Answers

It is significant because, this is where the stronger and more affinated genes are conceived, thus survive. 

Genetiic variation is simply the different variety of   genetic make up  and what is called alleles. Alleles are similar to a code for the body which determines such things as hair color, eye color, height, and other factors. 

Genetic variation is therefore the variation between genes and alleles, within a small or large group of people. A small group of people would for example be a family. A large group of people would for example be  the population of a certain geographic region such as a country.
