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:
The correct flow is - the body (a)<u> Venules/vein/vena cava</u> (b) <u>Right atrium</u> tricuspid valve (c) <u>Right ventricle</u> (d)<u> Pulmonary artery, </u>capillary bed of the lungs(alveoli)
Explanation:
Deoxygenated blood is moved from the tissues to the venules, veins or vena cava to the right atrium chamber and move through the tricuspid valve present in between both right chambers right atrium and right ventricle.
From the right ventricle, the deoxygenated blood is pumped into the pulmonary artery that takes the blood to the lungs more specifically to the capillary bed of lungs.
Thus, the flow is - the body (a)<u> Venules/vein/vena cava</u> (b) <u>Right atrium</u> tricuspid valve (c) <u>Right ventricle</u> (d)<u> Pulmonary artery, </u>capillary bed of the lungs(alveoli)
Answer: C
Explanation: Thymine pairs with Adenine and Cytosine pairs with Guanine.
Of or relating to genes or heredity.
"all the cells in the body contain the same genetic information"
Answer: centrioles and centrosomes
Explanation:
Centrioles are small granules found near the nucleus of ONLY animal cells from which flagella and cilia arise. Its functions include
- helping in cell division
- serving as basal body
Centrosomes also is located near the nucleus of animal cells and arranges microtubules. Its function is mainly giving protection to cell.
