Answer:
If the postsynaptic cell is an interneuron that uses GABA as a neurotransmitter, the excitation of this cell will result in an action potential in its synaptic targets.
The answer is OPTION B (False)
Explanation:
<em><u>Some terms explained:</u></em>
GABA:
known as gamma-aminobutyric acid (GABA), is an amino acid inhibitory neurotransmitter that decreases the neuron's action potential. It is well known to inhibit the activity of signal-receiving neurons.
The neuron will not generate action potentials when the action potential drops below a certain level, thus not excite nearby neurons.
Action potential:
An action potential is self-propagating in nature, is the mode through which a neuron transports electrical signals. Action potential of a neuron has three main stages: hyperpolarization, repolarization, and depolarization. It occurs when the membrane potential of a specific cell location rapidly rises and falls and it electrotonically depolarizes the membrane of regions in front of it.

The true statement regarding rigor mortis in fish is as follows: Rigor mortis can last anywhere from 10 to 15 minutes depending on the species, temperature, and condition of the fish when caught.
<h3>What is rigor mortis?</h3>
Rigor mortis is a temporary stiffness of a body's muscles and joints following death.
Rigor mortis occurs in fish after the fish dies. The symptoms are as follows:
- Harder texture
- Contraction of muscles
However, the appearance of the fish experiencing rigor mortis is dependent on the species of the fish.
Therefore, the true statement regarding rigor mortis in fish is as follows: Rigor mortis can last anywhere from 10 to 15 minutes depending on the species, temperature, and condition of the fish when caught.

Answer
The correct option is primary structure.
Explantion
A protein is composed of polypeptide chain which are organized into different structure as explain below:
Primary structure
The primary structure of protein is composed of a single polypeptide chain in which amino acids are arranged in linear form. Only covalent bond (peptide bond) hold the structure.
Example
Insulin hormone
Secondary structure
In secondary structure a single polypeptide chain is arranged in beta pleated sheet or in helical form. hydrogen bond and covalent bond responsible for providing stability to structure.
Example
Myoglobin
Tertiary structure
In tertiary structure a single polypeptide chain is arranged in three dimension. covalent bond, hydrogen bond and disulfide linkage help in maintaning this structure.
Example
Secretory proteins.
Quaternary structure
It is composed of more than one polypeptide chain and arranged in three dimension forming a globular structure. covalent bond, hydrogen bond, disulfide linkage, hydrophobic and hydrophilic interaction help in maintaining this structure.
Example
Haemoglobin.
