The goldfish (Carassius auratus) is a freshwater fish in the family Cyprinidae of order Cypriniformes. It is one of the most commonly kept aquarium fish. A relatively small member of the carp family (which also includes the Prussian carp and the crucian carp), the goldfish is native to east Asia. It was first selectively bred in China more than a thousand years ago, and several distinct breeds have since been developed. Goldfish breeds vary greatly in size, body shape, fin configuration and colouration (various combinations of white, yellow, orange, red, brown, and black are known).
Mechanical digestion is the physical breaking down of food particles into smaller food particles to increase surface area for chemical digestion. Chemical digestion is the use of enzymes to break down polymers into monomers (through the breaking of chemical bonds)
A lysosome is like the cleanup crew of the cell. One of its functions is the digestion of lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell. Lysosomes are also involved in the breakdown of organellesthat have outlived their usefulness. lysosome is like the cleanup crew of the cell.
