Understanding Natural Selection and Antibiotic Resistance

What causes strep throat?

• An allergy

• Bacteria

• A fungus

• A virus

What is 'fitness' in the context of natural selection?

• The physical strength of an organism

• The lifespan of an organism

• The speed of an organism

• The ability of an organism to reproduce

Why do darker frogs have more fitness in the given habitat?

• They are less visible to predators

• They live longer

• They are faster

• They are stronger

What is a mechanism of evolution demonstrated in the video?

• Genetic engineering

• Selective breeding

• Natural selection

• Artificial selection

How can bacteria become resistant to antibiotics?

• By increasing their size

• Through intentional changes

• Through random mutations

• By avoiding antibiotics

What is a potential consequence of using antibiotics when not needed?

• Strengthening the immune system

• Immediate recovery

• Selecting for resistant bacteria

• Reducing viral infections

Which vaccine can protect against bacterial infections?

• Flu vaccine

• DTaP

• HPV

• MMR

What is natural selection?

• The process by which individuals with beneficial traits produce more offspring

• The ability of an organism to change its color

• A random process that occurs without any environmental influence

• The process by which individuals learn to adapt to their environment

How can an organism's traits affect its survival and reproduction?

• Traits have no impact on an organism's survival

• Only brightly colored traits improve survival

• Traits that are well-suited to the environment can improve survival and reproduction

• Traits that are poorly suited to the environment improve reproduction

What is the significance of the peppered moth example in the study of natural selection?

• It shows that moths prefer peppered trees

• It demonstrates how a species can change color at will

• It illustrates how environmental changes can lead to changes in species through natural selection

• It proves that all moths will eventually become peppered
