Answer:
ligand; ions; ligand; ions; nervous system
Explanation:
Ligand-gated ion channels are transmembrane protein complexes that open when they bind to their corresponding ligands (e.g., neurotransmitters). This type of receptor is known to modulate the synaptic transmission between neuron cells or neuron and muscle cells. In the nervous system, ligand-gated ion channels located at sites of synaptic contact determine the ion flow in response to neurotransmitter binding. Some examples of ligand-gated ion channels include gamma-aminobutyric acid A (GABA-A) and nicotinic cholinergic receptors.
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

<span>The
building blocks of protein are amino acids. Amino acids produced by the cells
are synthesized in order to produce proteins. Vitamin B9(Folate) and Vitamin
B12(Cobalamin) are the two B-vitamins needed in amino acid synthesis. These
can be taken through dietary supplements.</span>
It will be Control. Part of the experiment used to show that the results of an experiment is really due to the conditions being tested.
Plant cells have a cell wall that is very rigid, which forces the cell to shape that way. Animal cells are round because they don’t have a cell wall only a plasma membrane
