Answer:

D

Explanation:

Water and air circulate around the world in water currents and wind systems (like prevailing winds) respectively, hence distribute energy and whatever else they are carrying across the globe. This is why polluting the oceans in the equatorial region will have indirect consequences for marine life in the poles.

Pollution of air through emission  of greenhouse gases in one part of the globe will contribute to global warming across the world because these emissions will be carried around by prevailing winds and diffuse across the atmosphere.

Global warming also causes climate change that subsequently causes the displacement or migration of organisms when this change in climate is unfavorable

Lena [83]

Answer:

The correct answer will be option-Base analog

Explanation:

5-bromodeoxyuridine is a synthetic nucleoside which is formed by deaminating the 5-Bromodeoxycytidine.  

The BrdU once incorporated in the DNA of replicating cell during S phase binds the adenine which shows that it replaces the thymidine which usually binds the adenine.

Since BrdU binds the adenine, therefore, it acts as the analogue of the thymidine and also can cause mutations thus acts as a mutagen.  

Therefore, it acts as a base analog and thus is the correct answer.

AnnZ [28]

Answer:

The lunar phases gradually change over the period of a synodic month (about 29.53 days), as the orbital positions of the Moon around Earth and of Earth around the Sun shift. The Moon's rotation is tidally locked by Earth's gravity; therefore, most of the same lunar side always faces Earth.
