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

Do organisms "decide" to evolve and change?

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

The differences among a species, like different bird beaks, are called

• genes.
• variations.
• traits.
• theories.

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.
