Question

A population of lizards lives in an isolated area where local rocks contain a high concentration of radioactive elements. A study of this population would MOST LIKELY show

Answer 1

That the lizards can tolerate a higher level of radiation

Answer 2

 B)  a higher than average mutation rate.

Radioactivity increases the rate and number of mutations in creatures that are exposed to it. When creatures are exposed to a higher than normal dose of radiation, they will show a higher than average mutation rate. The exact effect of these additional mutations cannot be predicted.
