Question is incomplete, The complete question is as follows:

When a bacterium such as E. coli is shifted from a warmer growth temperature to a cooler growth temperature, it compensates by:

A) increasing its metabolic rate to generate more heat.

B) putting longer-chain fatty acids into its membranes.

C) putting more unsaturated fatty acids into its membranes.

D) shifting from aerobic to anaerobic metabolism.

E) synthesizing thicker membranes to insulate the cell.

C) putting more unsaturated fatty acids into its membranes.

Explanation:

Bacteria has the ability to change the composition of fatty acid present in its cell membrane to compensate the change in temperature.

When bacterium E.Coli will shift from hight or warmer temperature to low or cooler temperature, it will put more unsaturated fatty acids into its membranes which will mintain the fluidity in the membrane.

Hence, the correct option is "C".

the answer is tropical areas. the tropical areas obtain more

radiant energy from the sun than they lose to space through terrestrial

radiation, and vice versa for polar areas. earth has an energy remaining in the

tropics and an energy scarcity for the polar areas.

explanation:

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
