Bacterial Resistance Review

When antibiotics were first developed, most infectious diseases could be controlled by them. Today, the diversity of bacteria is increasing, as certain bacteria are resistant to many antibiotics. One possible explanation for this change is that

• the bacteria needed to change in order to produce more antibiotics.

• some of the bacteria learned how to resist the antibiotics.

• antibiotics have become weaker over the years.

• the antibiotics killed most of the bacteria that did not have a mutation for resistance.

Which of the following would discourage the development of an antibiotic-resistant bacteria?

• increasing the use of antibacterial hand sanitizers and sanitizing lotions

• encouraging the use of antibiotics with farm animals to kill the bacteria first

Why does a pesticide lose its effectiveness over time?

• The pests become resistant.

• The pesticide accumulates in the bodies of the pests.

• The pests become contaminated.

• The pesticide expires within a week of being sprayed.

Most teachers have a list of needed classroom supplies that they request from their students. Why would a teacher intentionally leave hand sanitizer off of the list?

• The use of hand sanitizer combines strains of bacteria.

• Hand sanitizer only kills certain strains of bacteria, and each generation of bacteria becomes more resistant.

• Hand sanitizer is used too often, so the skin becomes more resistant and the bacteria less resistant.

• The use of hand sanitizer kills all bacteria, including the good strains

The ability of bacteria to survive and become "stronger" even after antibiotic treatment is called

• cellular respiration
• endospore formation
• antibody resistance
• antibiotic resistance
