RNA makes a copy of a gene from DNA to mRNA .
The evolutionary tree is not observed here but it is possible to answer this question by observing which nucleotide is found in the root of the node. It indicates the first substitution.
<h3>What is an evolutionary tree?</h3>
A phylogenetic evolutionary tree is a diagram used to show the evolution of a given taxonomic group (for example, a group of species).
It is possible to trace the evolution of a given taxon by tracing the nucleotide substitution observed from a common ancestor.
In an evolutionary tree, the root of the node is represented by the common ancestor and therefore the presence of a particular nucleotide (either T or C) in that position can be considered as the ancestral character.

Answer: First, the bacteria will adjust and then it will divide.
Explanation:
Once the bacterial species is put into the cultural medium, there the bacteria present in the medium needs to acclimatize in the medium and then start growing.
There is a lag phase before the log phase because first the bacteria will adjust into the medium and then start dividing.
As we know that the growing medium contains amino acids, growth factors, enzymes and many more things which first needs to be utilized by the bacteria and then it will start dividing.
Answer: Only a little colder.
Explanation: It started out much hotter, so it will stop cooling down before it reaches the same temperature as the room.
