Heightened sensitivity to a neurotransmitter after the destruction of an incoming axon is known as ____.

Biology
1 answer:
laila [671]3 years ago
4 0

Answer:

When an axon (nerve) damage or destruction occurs due to injury, it will increase the sensitivity to neurotransmitter by post-synaptic muscle membrane and this process is called the denervation super-sensitivity.

Explanation:

Basically, motor neurons releases and regulates a neurotransmitter acetylcholine at neuormuscular junction for sensitivity of the muscles. But when a nerve injured it will increase the sensitivity of muscle fiber to neurotransmitter acetylcholine. Means, after injury of nerve the muscle fiber become supersensitive to acetylcholine.

-The theory of evolution by natural selection states that organisms that are better suited for their environment will survive and reproduce, while those that are poorly suited for their environment will die off.

Explanation;

-The theory of evolution encompasses the well established scientific view that organic life on our planet has changed over long periods of time and continues to change by a process known as natural selection.

-Natural selection is the phenomenon that some traits confer a reproductive advantage (fitness), resulting in (a statistical expectation of) that trait increasing in the population over time (evolution).

Write a hypothesis about how the interaction of tectonic plates may cause earthquakes.
iVinArrow [24]

Answer:

hope this helps

Explanation:

Techtonic plates interacting with each other would cause an earthquake because they are essentially the earth's foundation so by sliding together they would  cause rockfall and make a rumble which is basically what an earthquake is and when they interact its basically the earth moving so it would cause shaking and rumbling which is what happens in an earthquake

(Additionally) in the aftermath of an earthquake the plates are either moving or settling down which is why frequently after an earthquake there is a mini one following it

In C3 plants the conservation of water promotes_______.a. photorespiration. b. a shift to C4.c. photosynthesis.d. the opening of
ankoles [38]

Answer:

A) photorespiration.

Explanation:

Photorespiration is the harmful metabolic process which takes place when the concentration of oxygen in the leaf increases compared to carbon dioxide.

The RUBISCO enzyme which usually binds the carbon dioxide now binds the oxygen and form the phosphoglycolate and 3 phosphoglycerate. The phosphoglycolate is lost through the Calvin cycle as Carbon dioxide molecule. This loss proves harmful to the plants.

The photorespiration occurs when the plant faces high temperature therefore n order to prevent water loss the stomata gets closed. This result in the binding of the oxygen to the RUBISCO and thus photorespiration begins.

Thus, Option-A is correct.
