Answer:
Inhibit control over ions.
Explanation:
The immediate effect of the neurotoxin on the postsynaptic neuron is to inhibit control over ion concentrations across the cell membrane. The neurotoxin blocks nervous transmission at synapses which prevents the vesicles containing the neurotransmitter from fusing with the presynaptic membrane so the information does not transfer from one neuron to another and as a result the body is present at constant relaxation mode. The membrane potential of postsynaptic neuron will decrease due to neurotoxin.

The discovery of the Rhesus factor affected society by improving the success rate of blood transfusions. Prior to the Rhesus system being implemented, blood was typed according to the ABO system alone. This meant a significant number of blood transfusions failed due to immunogenic reactions to the rhesus factor leading to agglutination of blood. It also helped prenatal care as people became aware of the possibility of the mother and child being Rhesus incompatible. This condition could be combated by an injection of antibodies.
