Which statement is TRUE about the synapse? Neurotransmitters shuttle the signal back and forth between the pre- and post-synaptic cell. The pre-synaptic cell and post-synaptic cell are in direct contact, allowing the electrical signal to seamlessly flow from one to the other. The action potential jumps from the pre-synaptic cell into the post-synaptic cell. The action potential ends in the pre-synaptic cell and neurotransmitters carry the signal across the synaptic cleft to the post-synaptic cell.

Immunology

Immunology is the division of science involved with the immune reactions occurring in living organisms. The organisms are accustomed to evolving internal defense mechanisms to evade the invasion of microbial pathogens. Diverse cells are connected with stimulating the immune responses, which produce inhospitable conditions to the microbes prompting their lysis and thus inhibits the multiplication of the pathogens. The immune system can distinguish the pathogens through the aid of cellular intercommunication and launch responses to destroy them.
