(a) concentration of carbon dioxide
(b) oxygen in trachea
(c) concentration of oxygen
(d) diaphragm expansion

Answer 1

Answer:

a)concentration of carbon dioxide

Explanation:

due to carbon dioxide many respiratory distress are found

Answer 2

The rate of respiration is directly affected by the concentration of carbon dioxide.

• Because the carbon dioxide concentration is high the rate of respiration is low.

• The rate of respiration is mostly dependent on the concentration of carbon dioxide.

• Not only carbon dioxide, the rate of respiration is affected by so many factors but highly affected by the concentration of CO2.

• Some of the environmental factors also affect the respiration rate that is oxygen,humidity, temperature, pollution, etc.
