Mutation in the gene of red blood cells results in the change of the shape of red blood cells from circular shape to sickle shape, a sickle shaped red blood cell transports less oxygen as there's a little haemoglobin content in that cell
Answer:
ligand; molecule; ligand; molecule; nervous system
Explanation:
Ligand-gated ion channels are membrane proteins that interact with ligands (molecules) and open in response to this binding. In the nervous system, these channels are activated by neurotransmitters (ligands) that regulate synaptic transmission between nerve cells (neurons). Neurotransmitters are signaling molecules clustered close to the cell membrane of axon terminals in presynaptic neurons. For example, glutamate is a ligand neurotransmitter that binds to ion channels and thus stimulates synaptic activity in the mammalian brain.
A correlation between variables indicates that as one variable changes in value, the other variable tends to change in a specific direction. ... For example, height and weight are correlated—as height increases, weight also tends to increase.
