The bunnies in a forest have different colored fur at different times of the year. The bunnies you see have brown fur in the fall. The bunnies you see in winter have white fur. What is this an example of?
a. Evolution
b. Artificial Selection
c. Natural Selection
d. Selective Breeding

A) Evolution or B) Natural Selection

Explanation: The fur of these bunnies change color with the seasons in order to better blend into their environment. This is an example of a species evolving to better survive!

However, this could also happen as a result of natural selection. Those who were able to better survive would pass on their genes for fur that changes with the seasons.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
