Answer:
d. axon
Explanation:
Neuron is the basic building block of brain and the central nervous system. They are specialized cells which transmit chemical as well as electrical signals.
<u>Axon is a part of neuron which carries electrical impulse from cell body to structures at the opposite end of neuron.
</u>
<u>It is a long and slender projection of neuron which conducts action potentials (electrical impulses) away from body of the cell. </u>
<u>Function of an axon is to transmit the information to the different neurons to different muscles and to different glands.</u>
Answer:
The given statement is false.
Explanation:
Hyperventilation is a condition when the rate of breathing increases resulting in the loss of more carbon dioxide from the body than the amount that the body can produce., thus dis balancing the equilibrium between the oxygen intake and the removal of carbon dioxide from the body and reducing the concentration of carbon dioxide from the blood.
With the reduced concentration of carbon dioxide in the blood the equilibrium of the carbonic acid in the blood is disturbed resulting in increase of hydrogen concentration in the blood.
Thus Hyperventilation causes reduction of carbon dioxide from the blood. Hence the statement is false as retention of carbon dioxide will cause increase in concentration of carbon dioxide.
