These demonstrations are a way for people to demand justice, equality, and an end to police violence. **

Proving involves establishing the truth or validity of something through the presentation of evidence or argument. It often requires a higher burden of evidence to establish a fact or claim. Demonstrating involves showing or illustrating the validity or truth of something through a clear and convincing display of evidence or examples. Providing evidence simply means offering information, facts, or data that support a claim or conclusion, without necessarily proving or demonstrating its validity. It is a more general term that encompasses the act of presenting supporting material for a particular assertion. **

A plant is kept in the dark before demonstrating starch because it allows the plant to use up its stored starch through respiration. When the plant is in the dark, it cannot photosynthesize and produce new starch, so it relies on its stored starch for energy. This depletion of stored starch makes it easier to detect the presence of new starch during the demonstration, as any starch that appears after the plant is exposed to light can be attributed to the process of photosynthesis. **
