Answer:
Researchers reported that people with high blood pressure were less reactive when shown photographs and text passages meant to trigger emotions including fear, anger and happiness. This weakened response could be called "emotional dampening," said James McCubbin, a psychology professor at Clemson University in South Carolina, who led the study.
Explanation:
Answer:
Axons with high diameter, and myelinated will conduct action potential faster.
Axons with low diameter but myelinated will be relatively slow in the speed of action potential transmission
Axons with high diameter and unmyelinated will be relatively slow in action potential transmission.
Axons with low diameter, and unmyelinated will conduct action potential slowly .
Explanation:
Diameter of Axon affects conduction speed of Action Potential; the thick axons with high diameter conducts action potential at a faster speed than thin neurons. This is because of the less resistance to the transmission of action potential along the thick axon. However, thin neurons with lower diameter has more resistance to the action potential conduct along the axon, thus the speed of transmission is slow.
Myelinated neuron transmits action potential faster because of jumping of action potential at the nodes of Ranvier where there is highest concentration of all channel proteins and pump proteins, Therefore action potential is conducted at a faster rate as it jumps from one node to another. This is salutatory conduction. It increases the conduct about 50 times compare to unmyelinated neuron. In neuron of human it increases the speed to 100ms-1
.Conversely, unmyelinated neurone conducts action potential slowly. About 0.5ms-1 . This is because no salutatory conduction takes place because there is no myelin interruption as Nodes of Ranvier
Answer:
d. alcohol inhibits the release of ADH
Explanation:
Alcohol play an opposite role in water reabsorption. ADH is made in supraoptic nuclues of hypothalamus and transfers fby neuron to posterior pituatry where it gets stored and secreted. Alcohol stops the release of ADH from posterior pituatry which decreases the serum level of ADH. As the ADH level lowers it wont be able to reabsorb water from the distal/collecting tubules of kidneys leading to increase in urine volume and urination.
If we say something is beneficial, it must be positive
and really mean to give advantage to one thing or another. Wave energy is a
renewable energy since it can be used repeatedly over time without any problem
on supply. Hence the greatest benefit it can give would be:
decreased use of nonrenewable resources
