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.
Vision is the least developed of a newborn baby's senses. <span>The visual capacity of the baby develops progressively in the first 8 months. From then on, the baby's vision will be as good as that of the adult. Although at birth, the eyes of the newborn have the physical ability to see without problems, your brain is not yet ready to process all that information; that's why he sees everything blurred. With the development of the brain, your visual ability improves.</span>
Engulfing is what happens during endocytosis, a form of active transport that takes large molecules into the cell. During this process, the molecule is trapped inside a newly-formed vacuole. Hope this helps! :)
