Answer: The most likely subject to be studied by a biologist is Biology. Biology as a subject is multi-disciplinary subject which means it includes all the parts related to both plants and animals. This includes zoology, botany, biochemistry, immunology, and many more. A biologist has all the information related to the metabolism of plants and animals. The growth, development, reproduction and some other issues related to animals and plants are looked after by the biologist.
B. In Antarctica
C. North of the Arctic Circle
D. North of the Arctic Circle and at high elevations
b. thymine and guanine
c. adenine and guanine
d. adenine and cytosine
Answer:
Cold, dense air near the poles sinks and moves toward the equator, where it is heated. After this, the warm air rises and moves back to the poles where it is cooled again.
Explanation:
In the poles, there are high-pressure zones due to the low temperature, and the cold and dense air. These high-pressure centres send winds or air to higher latitudes toward the equator. While this is happening, they get warmed as they travel and they start accumulating humidity. When they reach approximately 60 degrees latitude, they meet with warm winds that are coming from the horses' latitude (30 degrees latitude). They both ascend to the tropopause where they get cooled. As they cannot maintain humidity, it precipitates. Once done this, the winds move back to the poles, where they get cooler again, and so the cycle continues.
This cycle is known as the polar cell, and together with the Ferrell cell and the Hardley cell, they help modulate the clime.
Atmospheric convection involves the circulation of air, where cold, dense air sinks near the poles and moves towards the equator, where it is heated. The warm air then rises and moves back towards the poles to complete the cycle.
The process described in the question is known as atmospheric convection. Cold, dense air near the poles sinks and moves towards the equator, where it is heated. The warm air then rises and moves back towards the poles, where it is cooled again. This continuous circulation of air helps distribute heat and energy throughout the Earth's atmosphere.
