Chromalveolates is the answer i think
A Non-mutagenic factor listed in the options is : ( B ) Drinking water
<h3>Mutagenic factor </h3>
Mutagenic factors are chemical elements or various forms of radiations such as X-rays, UV rays, Sun rays, which may cause a permanent and heritable changes ( mutations ) in the DNA, when exposed to these mutagenic factors.
Hence we can conclude that a Non-mutagenic factor is Drinking water

Answer:
Petroleum, also called crude oil, is a fossil fuel. Like coal and natural gas, petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria. ... Millions of years ago, algae and plants lived in shallow seas
The use of mRNA and reverse transcriptase in this case is part of a strategy to solve the problem of post-transcriptional processing. So the correct option is A.
<h3>What is post-transcriptional processing? </h3><h3> </h3>
The process of transcription results in the formation of a heterologous nuclear RNA (hnRNA) or a precursor RNA (PreRNA). This undergoes post-transcriptional processing to form mRNA. Following are the steps -
- Splicing - it removes the non-coding introns so that only coding regions called exons remain.
- Capping - a 5'-methylguanosine triphosphate is attached at the 5' end of the RNA.
- Tailing - About 200 polyadenylate residues attach at the 3' end of the RNA.
These processes result in the formation of mRNA.
Therefore the correct option is A.
