Answer:
Polypeptide
Explanation:
Amino acids are the building block and simplest unit of protein molecules. The structural composition of each amino acids is made up of an amine group (-NH2), a carboxylic acid group (-COOH), a hydrogen atom (H) and a R side chain that differentiates every amino acid from one another.
In a reaction process called condensation, amino acids are chemically joined together via the amine group of one and the carboxylic group of another. This process releases water molecule (H20) to form a bond called PEPTIDE bond between the amino acids. Several amino acids in their 100’s or 1000’s that are chemically joined this way forms a POLYPEPTIDE chain, which in turn forms the protein molecule.
What work sheet? I'm great in Biology!
The absolute number of molecules of drug required to elicit a response
Answer:
Simple answer, yes.
Explanation:
Monocots have isobilateral leaf I.e both sides of the leaf are equally exposed to the sun.
Dicots have dorsiventral leaf I.e. ventral side is exposed to the sun more than the dorsal side.
They are very distinctly different from each other and can be separated easily, and so are their roots.
Cells don't grow very big because they have to be able to diffuse through material easily. Also, when cells are small and plentiful they are easy to replace when damaged.
