Evidence of evolution. Scientists support the evidence of evolution because of the adaptations organisms used to have in the past compared to the present. For example, humans have organs in their bodies they don't need, but must have been used in ancient times. They can also find that humans have a common ancestor such as monkeys because of the DNA similarities and many adaptations. Hopefully this answered most of your question.

What did you say about the cats in your room haha
One function of a plant stem is to transport water and nutrients from the roots to the other parts of the plant such as the leaves.
Another important function of the plant stem, because of its structurally rigid design, is to support the rest of the plant's body.
Plant stems also serve in elevating the leaves of the plant so that they can have better access to sunlight.
I hope this helped!
