Lynna [10]

The question is incomplete as it does not have the options which are:

A. bioremediation

B. mutualism

C. quorum sensing

D. quorum settling

E. mass-settling

Answer:

C. quorum sensing

Explanation:

Quorum sensing is the gene regulation mechanism used by the bacteria to communicate with the other bacteria.  The quorum sensing process depends on the number of bacterial cells or the density of the cells.

When the bacterial number increase in number then the bacterial cells send the signal to the nearby cells and and regulates the expression of the gene.  In the given question, the same chemical signal process depends on the density of the cell and thus quorum sensing is correct.

marin [14]

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.
