What is the main difference between bacteria and humans that gives Sulfa drugs their antibacterial properties? Group of answer c
sertanlavr [38]

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.

Early coal miners used canaries in cages as an early warning system to detect dangerous air
blagie [28]

Answer:

Because the Arctic glacier is crucial in cooling the land.

Explanation:

The glaciers contained in the Arctic are essential for cooling the earth's climate, which is why Arctic conditions are so important in determining the earth's climate changes.

These glaciers reflect about 80% of the sunlight in the northern hemisphere, and can cool the region's climate. If Arctic glaciers melt, most of the sun's rays will be absorbed by the ocean, increase the temperature and increase the melting of the glaciers.

As a result, the entire ecosystem will be damaged.
