The respiratory and circulatory systems work with each other in this manner, the respiratory system will obtain oxygen then the circulatory system brings the oxygen to different parts of the body then it also takes carbon dioxide from different tissues of the body and bring carbon dioxide to lungs then the respiratory system takes carbon dioxide outside the body during exhalation
Answer:
c. More oxygen and less carbon dioxide
Explanation:
The composition of air in the layers between the soil is called soil atmosphere or gas.
The maximum percentage of gas in soil is nitrogen with 79.2 %. Then it is oxygen with 20.6 % and the last is carbon dioxide with 0.25 %. These gases are required in order to maintain life under the ground. The roots of trees and the microorganisms require soil atmosphere to carry out their functions.
This is the chronicle of evolution over millions of years of geologic time engraved in the order which fossils appear in rock strata.
Runoff in neighborhoods can be a problem because as the water runs it can collect pollutants such as oil, pesticides, bacteria, etc. These pollutants can end up in our drinking water or can run into our fishing supply and even our swimming water... I wouldn't want to be swimming or eating fish that was swimming in pesticides and bacteria.
