Answer
<em>C. The Moon orbits the Earth about once a month</em>
Over billions of years the earth’s gravitational field has tidally locked the moon in orbit so that its rotation about its axis is the same as that of its orbit around the earth.
This process is still continuing as the earth transfers some of its angular momentum to the moon lifting it to a higher orbit by a couple of centimeters a year. As it rises, its takes a fraction longer to complete an orbit, and its rotational speed slows down slightly to match.
The eventual conclusion of this is that the earth also would become tidally locked to the moon, and they will both face each other permanently. But this is going to take that long that the sun will probably have destroyed both the earth and the moon in its red giant phase before this happens.

The two different molecules of aquaporin will have different sequences of amino acids
Explanation:
Aquaporins are an integral type of membrane proteins. They act as water channels and their function is to transport water and other solute materials across cells membranes and thereby control and regulate the water content of the cells.
They are formed by clustering of four water channel monomers forming a tetramer.
Each aquaporin is made up of a specific linear sequence of amino acids and variations in the sequence leads to formation of different aquaporins.
There are more than 10 types of aquaporins are known. The sizes of the aquaporins differ according to their pore diameter of each type and this difference leads to the selective permeability of water across cell membranes.

Please someone help I feel sickkkk
Involves actual transfer of electrons
Answer:
One could be in the cell. The cell respires, thus producing carbon dioxide in it. So the concentration builds up in the cell. Diffusion is the net movement of particles from a region of high concentration to a region of low concentration, and the carbon dioxide concentration outside the cell is less, therefore the carbon dioxide molecules moves outs of the cell.
Another scenario is when perfume is sprayed into the air. The perfume particles collides with the air particles (lower or no concentration of perfume). This process goes on and on. This is diffusion since the concentration perfume particles collides with the less concentrated particles of perfume.
