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:
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere
Explanation:
The categories of energy expenditure include the following:
- Resting metabolic rate - This is the total number of calories burned when your body is completely at rest and accounts for 60-75 percent
- Thermic effect of feeding - This happens during feeding in which the metabolic rate increases and heat is produced and accounts for 5-15 percent
- The thermic effect of activity - the amount of energy burned during all physical activity and accounts for 15-30 percent.
<h3>What is Energy expenditure?</h3>
These are the processes which involves how energy is used or spent. The categories are mentioned above with their appropriate explanations.
