What can you tell about this population of newts from the histogram

Look at Diagram 1. How could you describe this newt population?

• There are fifteen poison levels shown, and each individual has a different amount of poison.

• There is one poison level shown, and all newts have the same amount of poison.

• There are three poison levels shown, and no poison-level trait is more common than the others.

• There are three poison levels shown, and one poison-level trait is the most common.

Cactuses with longer spines are less likely to be eaten by sheep. If their environment changes to have many bighorn sheep, which of the following cactus populations will most likely survive?

• Populations 1 and 2 will most likely survive.

• Populations 2 and 3 will most likely survive.

• Only Population 2 will survive because it is the only population with variation.
