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.
We should suction the airway.
This is because the thick mucus and secretions should be removed from the trachea.
Answer:
Water is Polar
Explanation:
There is no overall charge to a water molecule, but there is a slight positive charge on each hydrogen atom and slight negative charge on the oxygen atom.
<span>Circadian rhythm</span>, also known as circadian clock or body clock is a biological process that follows a 24 hour cycle (approximately). It is said that circadian rhythm is dictated by natural factors in the body, as well as environmental signals.
Answer:
They use a gene modification technique called CRIPSR-CAS9. The pigs have been given a gene that allows them to better regulate their own body temperature, whereby they burn fat, or at which animals consume their own fat.
Explanation:
British and Chinese scientists explained that they conducted the study by adding a mouse version of the UCP1 gene used for porcine embryos, which is used to regulate body temperature characteristic of most mammals, but not ordinary pigs.
It is problematic for pigs to maintain a stable body temperature, and this is especially complicated in pigs that are cold in the winter months because they have not been able to "store" fat.
Inserting the UCP2 gene could solve this problem.
