A. They share a common ancestor because otherwise they would not have similar arrangements of bones. It doesn't matter that humans can't fly
The answer is A. Air
because our sound travel in the air so bat`s waves should travel in the air to find the insects that are flying in the air! :)))
i hope this is helpful
have a nice day
Answer:
According to Fick's law, the rate of diffusion of any substance across any barrier is<u> directly proportional to the surface area of the membrane or any layer exposed. and the concentration of the diffusing substance available, but the rate is inversely proportional to the diffusion distance available.</u>
<u />
Thus the rate at which oxygen will move across the phospholipid bilayer will depend on the concentration or amount per mole of the oxygen molecule hitting the phopholipid at a prticular time and how permeable the phospholipd layer is to oxygen molecules, but the rate of its movement across will be reduced as the distance between the phosphoslipid bilayer and the diffusing molecules increases.
Therefore, the concentration of oxygen should be maximised, the surface area of the phospholipid bilayer should also be maximized. the distances between the phopholipid and the vessel containing the diffusing oxygen molecules should be drastically reduced. With this Fick's law has been applied , and therefore maximum oxygen molecules can diffuse across.

Explanation:
In the upper thermosphere, atomic oxygen (O), atomic nitrogen (N), and helium (He) are the main components of air.
