The correct answer is - Troposphere.
The troposphere is the lowest part of the atmosphere. It is the densest part of it that borders with the lithosphere and the hydrosphere. The troposphere is the part of the atmosphere that supports all the life on Earth.
By polluting the troposphere, the effects on the human health will not be good at all, in fact it can be disastrous. The humans need air for the breathing, and the air that the humans breathe in is from the troposphere, so if the troposphere is polluted, than the humans will breathe in chemicals that are toxic and damaging for the human body. That will result in big problems with the health among the humans, especially health problems with the respiratory system, the heart, and cancer.
Answer:
False
Explanation:
We breath the carbon dioxide out and oxygen. The oxygen is required by the cell to produce energy while carbon dioxide is produced by the cells as byproduct and need to be exhaled from body. This exchange of gases is occur in lungs.
The membrane through which gaseous exchange occur in lungs is called as respiratory membrane or respiratory surface and is composed of the of alveolar epithelial cells and pulmonary capillary endothelial cells. Epithelial cells represents the cell on the outer surface of alveoli and endothelial cells represents the cells on the inner surface of capillary while pulmonary capillaries indicates the capillaries present in lungs.
So there is air present in alveoli on side of respiratory membrane and blood present on the other side of membrane in capillaries. The gases (Co2 and O2) diffuses according to difference in their partial pressure in alveoli and pulmonary capillaries.
The answer is No. <span>When sodium ions enter the cell, water does not exit to maintain fluid balance. I</span>f extra sodium ions entered the cell, then extra water must be given to keep the same density. Water does not exit, it must be added.
