Answer: Carbon dioxide
Explanation:
The forests and phytoplankton are carbon sinks, which absorbs the green house gas carbon dioxide from the atmosphere for photosynthesis. The carbon dioxide from the atmosphere and water are used as reactant in photosynthesis to yield carbohydrates and oxygen as products. Thus the carbon dioxide level in atmosphere decreases. This is necessary for controlling pollution in the environment and reducing the environmental temperature as carbon dioxide can make the environment warm.
The volcanoes may be dormant or not as active. Only very active volcanoes will be known for erupting a lot.
If the respiratory membrane is composed of two layers of
stratified squamous epithelium, it will mostly contain numerous cell layers
because it is its composition of having to be a stratified squamous epithelium.
Another thing, the tissue will most likely be a shield for this type of
epithelium will serve as a protection against abrasion of which the respiratory
membrane will be protected of.
