Answer:

A. Increasing surface area to improve nutrient absorption between the digestive and the circulatory systems.

Explanation:

Our intestines, on the inside, are lined with the intestinal mucosa. This mucosa is not straightened, as it might seem macroscopically; it rather has this wavy appearance forming folds. Also, epithelial cells in this mucosal layer have lots of small finger-like extensions called the villi.

Folds and villi increase the contact surface between the nutrients in the lumen and mucosa, thus increasing the rate of absorption of these nutrients between the intestines and the blood vessels below the epithelium.

Answer:

Since there is no distinction in the measure of the RNA polymerases yet rather their movement, the distinction lies in their structure and not their grouping. Adjustments are made to widen the states of endurance. Thus E. coli would not constrain it's endurance by restricting its development to hotter temperatures. Thus the appropriate response is "the RNA polymerase sub-units of the P. syringe strain most likely have additional adaptability with the goal that they can move all the more openly in colder temperatures".
