Why are there more newts with a high-poison level in the population in Diagram 3 than in the population in Diagram 1?

• more of the newts with low poison died out.

• more of the newts with high poison survived and did not reproduce.

• more of the newts with high poison survived and reproduced.

• more of the newts with low poison died out and didn't reproduce.

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 there are 5 of each.

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