Answer:
A. The RNA polymerase subunits of the P.syringae strain probably have extra flexibility so that they can move more freely in colder temperatures.
Explanation:
Because there is no difference in the amount of the RNA polymerases but rather their activity, the difference lies in their structure and not their sequence. Hence the answer can't be (B) or (D). Adaptations are made to broaden the conditions of survival. Hence E. coli would not limit it's survival by limiting its growth to warmer temperatures. Hence the answer is (A) the RNA polymerase subunits of the P. syringae strain probably have extra flexibility so that they can move more freely in colder temperatures.
Answer:
using spores which are nulbs
Explanation:
it is a fungi, meaning they use the spores
According to the research, a molecular clock can be used to determine the number of differences in a specific DNA sequence of two species (c).
<h3>What is a molecular clock?</h3>
It is a tool that allows us to relate the divergence time or the time elapsed since the divergence of two current lineages from their common ancestor.
It is based on analyzing and comparing the genetic material of organisms to establish the number of mutations.
Therefore, we can conclude that a molecular clock can be used to determine the number of differences in a specific DNA sequence of two species (c).

Answer: Induced fit model of the enzyme activity
Explanation:
The induced fit model of the enzyme was given in the 1894 as the lock and key model for the enzyme and substrate.
It states that the substrate acts as key to the lock of the active site. The substrate and active site of enzyme are perfect match of each other.
The enzyme finds the exact counter part during the chemical reaction. The enzyme optimizes to fit the substrate by stretching, restraining or squeezing.
