You would need data from a large number of people, best from a varied age and gender. For each person you would need pulse rate readings of the person at rest not watching television, watching an unexciting television program and watching an exciting sporting event on television. The pulse rates taken not watching television and watching an unexciting program serve as a control and comparison to eliminate the conjecture that watching any television causes pulse rate to increase. You would also have to be sure that each person is watching a sport that they consider exciting rather than one that you consider exciting, not everyone finds the same things exciting. The larger the body of data you accumulate, the more convincing your argument will be.
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.
The greatest advantage of using DNA technology to produce medicines has been that B. medicine can be distributed at a reduced cost. The medicine becomes easier to produce due to DNA technology. One may consider insulin as an example of this, which had to be extracted from the blood from animals before it could be produced using DNA technology.
