It would be C, The internal structure of cells withing the body. Microscopes are designed to look at cells, as the magnification is at that level.
The answer to this is C because humans don't have cell walls and if you are looking at an onion it has a cell wall because it is a plant.
Hydrolysis is the answer good luck
The correct answer is option C-glycogen
Glycogen is an immediate source of energy in animals. Glycogen is formed of small sub-units called glucose monomers. The process of formation of glycogen is called glycogenesis.
Glycogen is animal equivalent to starch.
When body need energy, the stored glycogen breaks down into small monomers called glucose and provide energy to the cell.
The excessive amount of glycogen is stored in muscles and liver.
Your answer is correct. Chitin provide the strength to insect exoskeletons. Cellulose is the strength for plant. Starch and glycogen are energy sources for life.
