Answer:
The addition and response to the net effect of postsynaptic potentials is called Spatial summation
Explanation:
Signal summation occurs when impulses received by a neuron are eummed together to reach the excitation threshold to fire a neuron. It occurs at the axon hillock of a neuron. Signal summation occurs since each neuron is connected to many other neurons, often receiving multiple impulses from them, both excitatory and inhibitory.
Signal summation can either be temporal or spatial.
Temporal summation, occurs when impulses received at the same place on the neuron in close temporal succession add up to initiate an action potential in the neuron.
Spatial summation occurs when impulses received simultaneously at different places on the neuron add up to initiate an action potential in the neuron.
Vidence of common descent<span> of </span>living organisms<span> has been discovered by scientists researching in a variety of disciplines over many decades, demonstrating the </span>common descent<span> of all </span>life on Earth<span> developing from a </span>last universal ancestor<span>. This evidence constructs the theoretical framework on which evolutionary theory rests, demonstrates that </span>evolution<span> does occur, and is able to show the natural processes that led to the emergence of Earth's </span>biodiversity<span>. Additionally, this evidence supports the </span>modern evolutionary synthesis<span>—the current </span>scientific theory<span> that explains how and why life changes over time. Evolutionary biologists document evidence of common descent by developing testable predictions, testing hypotheses, and constructing theories that illustrate and describe its causes.

C.Stimulation of thoracic or lumbar spinal regions,chain ganglion,acetylcholine release
Answer:
Roughly 96 percent of the mass of the human body is made up of just four elements: oxygen, carbon, hydrogen and nitrogen, with a lot of that in the form of water. ... Sulfur is not usually mentioned as a dietary supplement because the body gets plenty of it in proteins. Humans get nitrogen from food. The element is an important component of amino acids, which are used to build peptides and proteins. Nitrogen is also an essential component of the nucleic acids DNA and RNA and all of the other molecules derived from the nitrogenous bases.
