Biology Vocabulary

The movement of water from an area of high concentration to low, across a partially permeable membrane

What is the definition for Monomer?

• a molecule that can be bonded to other identical molecules to form a polymer.

• a substance that takes part in and undergoes change during a reaction.

• the species formed from chemical reactions.

• a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.

What is the definition for Protein?

• large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.

• a complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain.

• used to specify the acidity or basicity of an aqueous solution.

What is the definition for Nucleic Acid

• small molecules that are the building blocks of proteins.

• large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.

• a complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain.

• a compound consisting of a nucleoside linked to a phosphate group. Nucleotides form the basic structural unit of nucleic acids such as DNA.

What is the definition of Amino Acid?

• large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.
