Water moves via osmosis _________. a) from an area with a low concentration of water to one of higher concentration b) from an a
sp2606 [1]

Answer: c) from an area with a high concentration of water to one of lower concentration

Explanation:

Microscopically, we can interpret osmosis as the passage of water through holes in the membrane. These holes are small enough to allow water to pass through, but not to the ions that carry a layer of hydration, that is, a layer of water molecules around them. Water flows through the membrane in both directions. However, the occurrence of osmosis indicates that the flow is more intense in the direction of the less concentrated medium to the more concentrated. Thus, there is an effective flow of water in one of the senses, called osmosis, from an area with a high concentration of water to one of lower concentration.

Do you think these fish are an example of natural selection among two populations of the same species? Explain your answer.​
Tema [17]

Answer:

It depends on the fish (I do not see any pictures) Any fish is an example of natural selection.

Explanation:

A good example would be that polar bears grew and evolved to have white fur to blend in the snow to sneak upon prey. However, their brown bear counterparts failed to do that. So due to better camouflage and hunting technique, the polar bears survived more up north.
