Natural Selection Bell Work

What causes strep throat?

• A bacterium

• A fungus

• An allergy

• A virus

Why are antibiotics not effective against viruses?

• Viruses are too small

• Viruses have a cell wall that antibiotics can't penetrate

• Antibiotics target prokaryotic cells, not viruses

• Viruses are immune to all medications

What is a key factor in natural selection?

• The ability to move to different habitats

• Reproductive success

• The color of an organism

• The size of an organism

How do mutations affect an organism's fitness?

• All mutations are beneficial

• Mutations cannot change an organism's fitness

• Some mutations can be beneficial, harmful, or neutral

• Mutations make organisms less fit

What can cause antibiotic resistance in bacteria?

• Overuse of antibiotics

• Eating too much sugar

• Vaccinations

• Bacteria wanting to resist antibiotics

How do bacteria become resistant to antibiotics?

• By moving to a different environment

• Through random mutations that are selected for

• By increasing their size

• By avoiding antibiotics completely

Why is it important to only use antibiotics for bacterial infections?

• To prevent viral infections

• Because antibiotics enhance bacterial growth

• To avoid unnecessary costs

• To prevent the selection for resistant bacteria

What role do vaccines play in combating bacterial infections?

• They prevent bacterial infections, reducing the need for antibiotics

• They directly kill bacteria

• They make antibiotics more effective

• They cure bacterial infections

What is a consequence of antibiotic resistance in hospitals?

• Increased need for viral medications

• Decreased need for hygiene practices

• Increased difficulty in treating bacterial infections

• Decreased effectiveness of vaccines

How do resistant bacteria spread resistance to other bacteria?

• By changing their color

• By transferring genes to other bacteria

• By consuming antibiotics

• Through reproduction only
