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 monomer is the subunit of a polymer and the building blocks of polymers. Polymers are the large carbon based molecules while the monomers are the smaller molecules. Question 2 Explain how both nucleic acids and proteins are polymers. Be sure to describe the monomers that make up the polymers.Nucleic acids and proteins are both polymers because they are composed of many smaller subunits-monomers. Nucleic acids are composed of polymers of monomers called nucleotides.roteins are also polymers-they are composed of groups of monomers called amino acids. Amino acids are molecules comprised of hydrogens, nitrogens, carbons, oxygens, and a variable group which ranges between 20 different possible atoms.
