Answer:
Industrial smog results from the combustion of fossil fuels and photochemical smog forms when sunlight drives chemical reactions between primary pollutants and atmospheric compounds.
Only small, uncharged molecules (like 02 for example) can go in or out of the cell by simple diffusion.
Since glucose is a relatively large molecule and ions (like Na+, Cl-) have an electric charge, they are unable to diffuse into or out of the cell.
However, since ions, glucose and other big or charged molecules are necessary for the functioning of the cell, there are special means of transport for them.
Integrated into the cell wall there are membrane proteins which serve as canals for transporting specific molecules like ions, glucose, etc.
Sunlight help to provide energy to the plant to complete the process. Basically, the plant harvest the solar energy.
Answer:
Dopamine
Explanation:
Dopamine receptors type 2 (D2) are expressed in the adrenal glands. More so, dopamine helps in the modulation of aldosterone and catecholamine secretion from the adrenal gland.
Carbohydrates are molecular compounds made from just three elements: carbon<span>, hydrogen and oxygen.</span>
