Enzymes
During digestion, enzymes break down nutrients into forms that can be readily absorbed by cells. This process involves breaking down complex molecules into simpler forms that can be transported through the bloodstream and used by cells for energy, growth, and repair. Once absorbed, these nutrients can enter various cellular metabolic pathways to provide the necessary components for cellular function.
Crayons changing the color on paper is a physical change because it does not alter the chemical composition of either the crayon or the paper. The change is reversible, as the color can be erased or removed without chemically altering the substances involved.
These are physical changes.
The name for a protozoan of ever changing shape is Amoeba. Amoebas are single-celled organisms that constantly alter their shape as they move and feed.

You alter the brightness of a bulb by changing the voltage or frequency that is applied to the bulb.
There is no known way to alter a object's density without chemically changing the substance. If you want it to float, remove enough of the substance so buoyant force could keep it afloat.
