Answer:
The starch in the plant was removed
Explanation:
When a plant is placed in a dark cupboard for 24hrs it won't receive any sunlight meaning it won't photosynthesize. This results in the plant using up it's stored starch for growth.

Answer:
The water carried the pieces of paper to the sides of the container.
Explanation:
The convection model shows how Earth’s mantle moves Earth’s plates. It also describes how hot rock flows in the Earth's deep interior in order understand fully how this particular flow shapes the surface of the Earth.
The convection model talks about how the temperature of the solid due to an external field such as fluid buoyancy can induce a fluid motion. This explains why water carried the pieces of paper to the sides of the container.
The independent variable has to do with the amount of water put onto the rock; the dependent variable is the mass of the rock after it has been in the water.
