Answer:
Nerve cells release chemical signals into synapses between them (short distance). They also transverse their lengths with an electrical signal that can result in signal travel along a series of cells (long distance).
Explanation:
Nerve cells release neurotransmitters in the synaptic cleft which are capable of affecting nearby cells such as other nerve cells and muscle cells. Neurotransmitter molecules include, among others, serotonin, acetylcholine, dopamine, norepinephrine and histamine. Moreover, the synaptic cleft is the space that separates a neuron cell and its target cell. On the other hand, neurons transmit signals through electrical impulses. Electrical impulses travel long distances in the body carried by axons of the nerves. Thus, nerve impulses connect the brain and spinal cord and they carry signals to different parts of the body.

Answer:
b. How does food yield energy?
Explanation:
The main question is how energy is produced from food such as carbohydrates, fats and proteins etc. First the carbohydrate is converted into glucose molecule and then glucose is absorbed by the cell and is broken down in the mitochondria of the cell with the addition of oxygen and generate energy in the form of adenine tri phosphate. All the scientists wants to know that how a food is converted into energy.
