Answer:

Human cells can readily absorb folic acid; bacteria cells cannot.

Explanation:

Bacterial cells cannot absorb folic acid and synthesize it. On the other hand, humans do not synthesize folic acid in their cells. They rather obtain it from the diet. Sulfa drugs, for example, sulfanilamide resemble p-aminobenzoate (PABA). PABA is a molecule that is used as a substrate in the synthesis of the coenzyme folic acid. The sulfa drugs serve as competitive inhibitors and compete with PABA for the catalytic site of an enzyme involved in the folic acid synthesis. This prevents the synthesis of folic acid in bacterial cells and thereby, inhibits bacterial growth.

Answer:

The correct choice is A)

There will be fewer producers in the area.

Explanation:

Very easy to deduce. A producer in biology of ecosystems is an organism that produces its own food. Another word for a producer in biology is 'autotroph'.

They produce energy directly from the energy given off by the sun or chemicals or both.

Grass (or plants) are producers. They do this with the help of water, converting solar energy into sugar or food, which are usable forms of energy.

So the more grass is consumed, the fewer producers in the area.

Cheers!
