The theory of evolution by natural selection means that what is changing over time?

• The inherited traits of a population.
• The acquired traits of a population.
• Hair color and eye color
• Attractive features.

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

Why do frogs and other organism reproduce so many eggs or offspring?

• so that their babies can have friends to play with
• the more offspring the more likely the offspring will survive
• the more offspring the less likely offspring will survive 
• the more offspring the less competition

Which organisms are most likely to survive?

• the best adapted to their environment.
• the fastest in the environment.
• the strongest in the environment.
• the most domesticated (tamed)

Almost all adaptations started off as?

• selective breeding
• physiological
• structural
• mutations

Do organisms "decide" to adapt to a change in their environment? 

• Yes, they know they need to change to survive 
• No, they change because of natural selection
