Question

check your understanding
1 what causes the skin coloration in the tree frogs to differ?
2 how can natural selection explain the changes in tree frog skin coloration over time?
3 radiation levels in the chernobyl area will continue to decrease over time. what do you think will happen to the skin coloration of the tree frogs in the future?

Explanation:

The problem is about tree frogs' skin coloration, likely related to biological concepts like genetics, natural selection, and environmental factors (radiation here). Biology (subfield of Natural Science) deals with living organisms' traits, evolution, and responses to environment, so it's the best fit.
