The kind of adaptation in this case is defense. Some plants have evolved poisonous leaves as a defense mechanism to protect themselves from being eaten by animals.
The plant is demonstrating phototropism. Phototropism is the growth or movement of an organism in response to light. In this case, the plant is growing towards the window to receive more sunlight, which is a positive phototropic response.
The independent variable in this experiment is the amount of light the plants receive. The students are investigating how the amount of sunlight affects the size of clover leaves, so they are manipulating the independent variable, which is the amount of light the plants receive.

Students are conducting an experiment to determine if the amount of sunlight affects the size of clover leaves. They plant clover in two identical pots, placing one next to a window and one inside a cupboard. They water each pot daily with 10 mL of water. Which is the independent variable?(1 point)

A scientist has two identical plants placed by a window. One is in a red pot, and the other is in a yellow pot. She waters the one in the red pot with regular water and the one in the yellow pot with nitrogen-enriched water. After 5 days, she counts the number of flowers on each plant. What was her scientific question?
