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 organism knew it needed that trait, survives, and passes it on.

The differences among a species, like different bird beaks, is called ...........................

• genes.

• variations.

• traits.

• theories.

Hover your mouse over the image to make it bigger. What process is being shown in this image?

• Variation

• Natural Selection

• Selective Breeding

• Homeostasis

Organisms that are better adapted to the environment survive to pass traits to their offspring. What do we call this process?

• Natural Selection

• Homeostasis

• Selective Breeding

• Extinction

The more genetic variation a population has,

the more likely it is for some individuals to ......................

• evolve

• migrate

• survive

• mutate

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
