Amoeba is the mass of a loving protoplasm
<span>These are excitable and action potential cells, because when they receive a stimulus they activate an action potential, these stimuli are electrical, chemical, mechanical and photonic. The action potential changes rapidly in the membrane potential in response to a stimulus and returns a resting potential. The action potential has several stages, and its main characteristics are that nothing is produced or produced when generated is maintained and propagated, the time of the voltage-dependent channels remain open. The types of the action potential are spike potential, plateau potential, potential and rhythmic potentials.</span>

Answer: C
An amino acid has a central carbon atom surrounded by a hydrogen atom, a carboxyl group (-COOH) , an amino group(-NH2) and an alkyl group(-R). Hence if an a molecule has a singlt hydrogen atom which is bonded to a central carbon atom, an amino group and a carboxyl group both bonded to the same carbon atom, a R group which is also attached to the central carbon atom, the molecule is an amino acid(a monomer).
