I'm going to guess on your unmentioned following and say that it is not derived from beans, eggs, milk, and so on because a lipid is an oily, greasy and waxy molecule found inside of a body. Lipids can normal be extracted from cells using non-polar solvents such as chloroform or benzene. Hope this helped!
Answer:
The correct answer is "photorespiration".
Explanation:
Photorespiration is a process in plants, where molecular oxygen is taken in a light-dependent manner. Photorespiration is often considered a wasteful pathway because it competes with the Calvin cycle, which is much more efficient. In C3 plants the conservation of water promotes photorespiration. This occurs when the C3 plants close its stomata because the environment its too hot, or the carbon dioxide concentration drops to about 50 ppm.
<span>Air pollution has a variety of effects upon health, including biochemical, physiological and breathing difficulties (such as increased coughing, increased C02 intake, restricting air flow, disrupt ventilation etc). The statement "It could restrict air flow through the bronchi" doesn't explain the effect of air pollution effectively enough.</span>
