The surface of a leaf has many tiny pores, called stomata. The stomata allow carbon dioxide into the leaf so that photosynthesis can occur. They also allow water to leave the leaf by transpiration. Plants that grow in full sunlight usually have most of their stomata on the shaded undersides of their leaves.
Answer:
Option A, Glucose metabolism in the fetal brain increased
Explanation:
Usage of cocaine during pregnancy is prohibited. However, in case if cocaine is taken it disrupts the metabolism as it increases brain glucose metabolism to the level of an adult human being. Since glucose metabolism in brain is a sensitive process, any disruption in it can lead to unaccounted effects such as dysfunctional circulation, and pharmacological effect. Cocaine increases the dopamine by blocking the dopamine transporters thereby increasing the Vmax. Since the brain of a child has all kind of neurochemical components, cocaine intakes by a pregnant woman produces reinforcing effects in brain of fetus and also make it pharmacologically active
Hence, option A is correct
Plants stored carbon in their tissues to use as energy and plants took in carbon dioxide and released oxygen through photosynthesis. Thus, the correct option is A and D.
<h3>
What is carbon cycle?</h3>
The carbon cycle is the ongoing process through which carbon atoms move back and forth between the atmosphere and the Earth. The amount of carbon in this system does not fluctuate because our planet and its atmosphere are a closed environment. The location of the carbon, whether it is on Earth or in the atmosphere, is continually changing.
Plants use photosynthesis to transport carbon from the atmosphere into the biosphere and move it up the food chain. They make sugar molecules by chemically combining carbon dioxide with oxygen and hydrogen from water using solar energy.
