If Easter eggs were living species of organisms, their different colors would be considered:
The peppered moth's color camouflaged it on the light colored tree bark. It's color was an example of a/n
Where are hereditary traits stored in all organisms?
In the DNA
Why might it be helpful for a species to have a lot of variations?
If the environment changes, they might be better able to adapt
If a sick person takes an antibiotic but it doesn't kill all of the bacteria causing the sickness, what might explain this?
Variations in the bacteria allowed some organisms to be less affected by the antibiotic?
Changes in inherited characteristics can cause a species to change into a new one. This change over time is called?
On the Galapagos Islands, different finches evolved on different islands to fit their environment. When a species develops unique traits because it is trapped in one area this is called:
One female salmon can lay hundreds of eggs. Why doesn't the salmon population increase dramatically?

Survival of the fittest
It took millions of years for giraffes to develop long necks. Slow evolution is called:

The inherited traits of a population.

Mutations are a change in what?
Why are advantageous traits more likely to be passed onto offspring?

What is the advantage of having different shaped beaks?
To be able to eat the food readily available in the environment.
