Ocean gyres can select all that apply. a. make hot climates cooler b. make hot climates warmer c. make cool climates cooler d. make cool climates warmer

Option (A) and (D)

Explanation:

Ocean gyres are the system of oceanic water circulation that occurs due to the prevailing wind patterns and the forces that are initiated by the rotation of the earth. This continuous motion of ocean gyres forms a conveyor belt that circulates the water from the equatorial to the polar regions in both the hemisphere. It maintains the overall temperature, amount of nutrients, and the salinity of the ocean water.

These ocean currents are diverted towards the right by the Coriolis force that occurs due to the earth's rotation.

The ocean in the equatorial region is warmer than the water at the higher latitudes. It is because of the higher amount of sunlight that falls in this region. At higher latitudes, the temperature is relatively low and there the waters are much colder.

These ocean currents circulate in both the hemisphere, carrying the hot and warm water from the equator to the polar region and in return, carries the cold water from the polar to the equatorial region.

Thus, it can replace a hot climate by a colder one and a cold climate by a hotter one.

Hence, the correct answers are an option (A) and (D).

Aspects of evolution are constantly being challenged and explored in light of new evidence

Explanation:

The whole idea of evolution has to do with the fact that organisms developed into their present form from simpler life forms. According to Oxford dictionary, evolution is; ''the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth.''

Evolution depends on evidence from fossil records. Evidences that support the theory of evolution continue to be amassed as science advances. Hence, aspects of evolution are constantly being challenged and explored in light of new evidence.

For this reason, the evolutionary history and development of whales is being hotly debated and there has recently been a major shift in our understanding of the processes used to detail whale evolution.
