A researcher observes that a population of desert plants has developed thicker waxy coatings on their leaves over many centuries.
This change is an example of:
- Natural selection, as the coating helps prevent water loss in a harsh climate.
- Osmosis, because the waxy coating is made of water that diffused from the roots.
- Homeostasis, as the plant individual changed its DNA to stay cool during the day.
- Mitosis, which allowed the leaf cells to divide more quickly under the hot sun.
