Answer:
b. Elongation
Explanation:
During the start of the elongation phase of RNA synthesis, the sigma subunit of RNA polymerase of <em>E. coli</em> is released and NusA protein takes its place. This makes the RNA polymerase to move away from the promoter.
During the elongation phase of RNA synthesis, the enzyme DNA dependent RNA polymerase elongates the RNA strand by addition of ribonucleotides to the free 3'-OH end. The process occurs in 5' to 3' direction and the 3'-OH group serves as a nucleophile.
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:
Zooplankton - Animals (mostly microscopic) which drift freely in the water column.
Explanation: Zooplankton, small floating or weakly swimming organisms that drift with water currents and, with phytoplankton, make up the planktonic food supply upon which almost all oceanic organisms are ultimately dependent.
