Answer:
D
Explanation:
An enzyme called poly (A) polymerase (PAP) is part of the same protein complex that cleaves the pre-mRNA and it immediately adds a string of A nucleotides, called the poly (A) tail, to the 3′ end of the just-cleaved pre-mRNA. The poly (A) tail added protects the mRNA from degradation, aids in the exportation of the mature mRNA to the cytoplasm and helps in binding proteins involved in initiating translation.

Respiration and photosynthesis because both happen through the leaves of any plant.
<u>Condensation</u> is the next step in the water cycle that is most likely to happen next as water molecules evaporate from a lake near the equator and rise into the atmosphere, as shown in the diagram below. and as the molecules travel away from the equator.
Explanation:
As the warmer air mass rises into the upper atmosphere, at the equator, it begins to cool because temperatures drop with altitude. The relative humidity of the air mass increases until it reachesdew point. The water vapor begins to condense into water droplets.
This air mass begins moving towards the poles (away from the equator) bringing with it clouds (condensed water vapor) that precipitate later on. This air mass begins to sinks because it has become denser with a decrease in temperature. As it sinks it replaces the air mass moving to the equator. The air rushing to the equator is replacing the rising warm air mass at the equator. This cycle continues.
