Answer:

D) splicing together of introns through rna processing

Explanation:

Transcription is the process by which an mRNA molecule is synthesized using a DNA template. However, the initial mRNA transcript is considered pre-mRNA until it undergoes post-transcriptional processing to become matured. The mRNA processing involves three steps viz: capping of 5', polyadenylation and splicing.

The 5' end of the mRNA molecule is capped with a 5' cap in the first mRNA processing stage. This is followed by the addition of a poly(A) tail to the 3' end of the mRNA strand. The last step called Splicing involves removal of introns (non-coding regions of sequence) from the mRNA sequence while the remaining protein-coding regions called EXONS are joined or spliced together.

Hence, option D which says: splicing together of introns through rna processing is not correct because exons are spliced together during splicing step of mRNA processing.

➷ The correct answer would be D. Products of one process are used as some of the reactants for the other processes.

As you may know, the formula for photosynthesis is:

carbon dioxide + water ==> oxygen + glucose

And the formula for respiration is:

oxygen + glucose ==> carbon dioxide + water

The reactants for one are the products for the other and vice versa. This is why it would be the correct option.

Auroras are lights that appear at Earth’s northern and southern poles. What is the main cause of an aurora?

deff fn [24]

When charged particles from the sun strike atoms in earth's atmosphere, it causes electrons to move to a higher energy state. When the electrons drop back to a low energy state they release light photons. This is what causes the Aurora lights
