What is the meaning of 'survival of the fittest'?

• Animals that can camouflage survive

• The strongest animals survive

• Only the fastest animals survive

• Individuals with traits beneficial for survival are more likely to reproduce

What is the difference between a theory and a hypothesis?

• A theory is a guess, a hypothesis is proven

• A theory is proven, a hypothesis is an initial explanation

• A theory is a law, a hypothesis is a guess

• A theory and a hypothesis are the same

What is artificial selection?

• Plants adapting to the environment

• Animals selecting their mates

• Selection by natural processes

• Humans selecting traits to increase in a population

Why are both light and dark pocket mice common in the desert?

• Because of their food sources

• Due to mutation

• Because of genetic drift

• Traits help them adapt to different environments

What can be a drawback of artificial selection?

• Increased biodiversity

• Selected traits may lead to health problems

• Faster evolution

• More natural environments

How does natural selection affect a population?

• It increases the population size

• It decreases genetic variation

• It has no effect on the population

• It changes the traits that are advantageous for survival
