Answer:
chemical reactions.
Explanation:
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.
The Lokiarchaeota cell is one of the only ones they have yet to find out stuff about. Scientists also need to know about it because it is apart of our body and maybe sometimes they can cause infection in the body. Scientists need to know if it could lead to to some of the biggest infections ever. (I rlly Hope this helps you)

Answer:
The correct option is A) RNA polymerase.
Explanation:
RNA polymerase is an essential enzyme complex to carry out transcription, these enzymes are responsible for transcribing DNA into RNA. Using a DNA template, RNA polymerase builds a new RNA molecule through base pairing. This process is the first step of gene expression, and is called transcription. RNA polymerase binds to DNA in a very particular region or sequence, called a promoter.
