Sunday SAT question

Bacteria is becoming resistant to many human-made antibiotics, which means that the drugs no longer affect the bacteria. Scientist now face the challenge of developing drugs that can overcome the resistant strains of bacteria.

Antibiotics from animals are different from human-made antibiotics.These antibiotics bore holes through the membranes that surround bacterial cells, causing the cells to disintegrate and die. Bacterial membranes don’t mutate often, so they are less likely to become resistant to animal antibiotics.

1. In the passage, what does the word mutate mean?

2. Based on the passage, which of the following statements is a fact?

c. all strains of bacteria mutate

d. bacterial membranes never change

3. Based on the passage, which one of the statements is false?

a. antibiotics from animals are different from human-made antibiotics

b. antibiotics from animals bore holes in bacterial membranes

c. bacterial membranes don’t change very often
