Natural Selection and Antibiotic Resistance Quiz

What is the primary purpose of antibiotics?

• To enhance immune response

• To treat viral infections

• To destroy prokaryote cells

• To destroy eukaryote cells

In the frog example, what determines a frog's fitness?

• How long it lives

• How many offspring it has

• Its ability to change color

• Its size

Why are lighter frogs selected against in the given habitat?

• They have a shorter lifespan

• They cannot reproduce

• They are less aggressive

• They are more visible to predators

What is a key factor that contributes to genetic variation in a population?

• Environmental changes

• Mutations and crossing over

• Predator presence

• Dietary habits

Can organisms will themselves to have beneficial mutations?

• Only in certain environments

• No, mutations are random

• Only during reproduction

• Yes, if they try hard enough

How do bacteria develop resistance to antibiotics?

• By willing themselves to change

• Through random genetic variations

• By avoiding antibiotics

• Through exposure to viruses

What happens to bacteria that do not have traits to survive antibiotics?

• They become stronger

• They hide from the antibiotics

• They die and cannot reproduce

• They mutate immediately

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

• To save money

• To prevent resistance development

• To avoid side effects

• To boost the immune system

What is one way bacteria can share resistance genes?

• By mutating rapidly

• By transferring genes to other bacteria

• By avoiding antibiotics

• Through direct contact

What can vaccines like the DTaP vaccine protect you from?

• Allergies

• Bacterial infections like diphtheria, tetanus, and pertussis

• Fungal infections
