physical change
The biggest advantage of chemical change is life. All organisms are alive because of the sum total of all the chemical reactions occurring in their cells.
The Chloroplasts
Green plant cells change light energy into chemical energy.
Hair (newly grown) is a product of many (bio)chemical synthesis reactions.
Nerve cells are specialized cells for neuron function by bio chemical ion diffusion to transmit electrical impulses as information from neural cortices to muscles/organs for coordination of body function.
Grape juice contains mostly glucose (C6H12O6) and wine also has ethanol (C2H5OH). The ethanol is produced by fermentation of glucose by yeast cells. This is a chemical change.
When muscles are over-exerted, the muscle cells carry out anaerobic respiration to compensate for the oxygen deficit. Lactic acid produced as a result of this causes muscles to become sore or develop cramps.
As in all types of cells, muscle cells store energy in a chemical called adenosine triphosphate, also called ATP.
no it is a color dye added to the dead cells that are your hair.
