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)
Hydrolysis is the process by which polymers are split into monomers; a molecule of water is used to split each bond between monomers. Carbohydrates are biological molecules made up of carbon, hydrogen and oxygen. They function as a major source of energy for plants and animals and also a structural molecule in plants.Monosaccharides (sugars) : are the basic monomer units of carbohydrates.Monosaccharide molecules usually have the formula (CH 2 O) n.iological Molecules. Monomers and Polymers: Monomers are small molecules that combine to form long chain molecules known as polymers (see Chemistry section for further details). Condensation is the process by which two monomers bond to each other; a small molecule (usually water) is lost from the resulting molecule.
