As a whole, plants tend to release more oxygen than carbon dioxide into the environment, but the ratios of gases differ at various times of the day. Plants tend to take in more carbon dioxide during the day and release more oxygen. At night, they tend to take in more oxygen and excrete more carbon dioxide. How does the model support this phenomenon?

within 30 of the equator hope this

im not intirely sure but i think the anwser is d relative humidity

you know that this symptom is misleading and quite often is related to: heart attack

a heart attack is a condition that occurs when the blood flow that transports oxygen to the heart muscle is damaged or cut off completely. the coronary arteries that supply the heart muscle with blood flow can be blocked by the accumulation of plaque. also, when the plaque within the heart artery breaks, it creates blood clot that can also hinder the blood flow. men that are over 45years of age and women that are over 55years of age are at risk of having a heart attack. the symptoms of a heart attack include chest discomfort, chest pain, coughing, and shortness of breath.
