What is the purpose of photosynthesis?
Answer:
To make food for the plant.Explanation:
Photosynthesis is the process of green plants and some prokaryotes (cyanobacteria) producing glucose and oxygen gas from carbon dioxide and water, in the presence of sunlight.Mira analyzed oxygen and carbon dioxide in inhaled and exhaled air. she found that the percentages of both gases were different in each. what other gas would most likely also have different amounts in inhaled and exhaled air? ozone (o3) hydrogen (h2) water vapor (h2o) sulfur dioxide (so2)
The amount of different gases varies in environment. Just like oxygen and carbon dioxide, Water vapor also have different amounts in inhaled and exhaled air.
What is breathing?Breathing is the process of inhaling oxygen and removing carbon dioxide.
During breathing amount of inhaled air contains 21% of oxygen and 0.04% of carbon dioxide,while during exhalation 16.4% of oxygen and 4.4% of carbon dioxide is there.
The reason behind such variation is that cells use oxygen from the inhaled air to release energy and give out carbon dioxide as a byproduct.
Water vapor is also inhaled and exhaled in different amounts just like oxygen and carbon dioxide.
Thus, the correct option is C.
