The correct option is (A) solar radiation strikes the poles at a lower angle and travels through more atmosphere.
The main reason polar regions are cooler than the equator is that solar radiation strikes the poles at a lower angle and travels through more atmosphere.
<h3>
Why polar regions are cooler than the equator?</h3>
- Because they get much less solar energy than the tropics and mid-latitudes do, the earth's two pole regions are chilly.
- At either pole, there are six months of nonstop darkness and the sun never rises higher than 23.5 degrees over the horizon.
- Furthermore, the dazzling white surface reflects the majority of the sunlight that does reach the polar areas.
- The Arctic Ocean serves as a useful heat reservoir, absorbing heat from the atmosphere in the summer and warming the chilly winter environment.

Answer:
During respiration, cells break down simple food molecules such as sugar and release the energy they contain. an energy releasing process that does not require Oxygen. In the mitochondria, the smaller molecules combine with oxygen to produce water and carbon dioxide. This reaction realeases a large amount of energy.
Explanation:
<h2>Answer is option "1"</h2>
Explanation:
- Infections are not plants, creatures, or microorganisms, however, they are the quintessential parasites of the living realms. Despite the fact that they may appear living organisms as a result of their gigantic regenerative capacities, infections are not living organisms in the exacting feeling of the word.
- Without a host cell, infections can't complete their life-continuing capacities or recreate. Infections can't produce or store vitality as adenosine triphosphate (ATP), however, need to determine their vitality, and all other metabolic capacities, from the host cell.
- Hence, the right answer is option 1 "viruses are not capable of metabolic activity on their own; they must have a host cell to reproduce."
