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.

What are the contributions of each of these scientists to the cell theory? And how did that information contradict what was beli
SpyIntel [72]

M. J. Schleiden:

In the year 1838, a German botanist presented the first cell theory (Although his theory was ultimately disproved, it did contribute to a change in scientific focus to cellular processes.)

<h3>What is cell?</h3>

All living creatures and body tissues are made up of the smallest unit that can live on its own. The cell membrane, nucleus, and cytoplasm are the three primary components of a cell. The cell membrane encloses the cell and regulates the molecules that enter and exit it.

His theory: Cells make up all plant tissues, and an embryonic plant is made up of just one cell. He declared that the cell is the fundamental building block of all plant matter.

Louis Pasteur- 1855 - German physiologist, physician, pathologist; and anthropologist. Added a third to the cell theory: Omnis Cellula e cellula (all cells develop only from existing cells).- Implied that there was no Spontaneous generation.

Rudolf Virchow- In 1862 he conducted a famous experiment supporting the theory that cells can only come from other cells.

His experiment:

Steralized flasks with straight and curved necks were used to heat nutrient broths. Bacteria only developed in the straight necks because bacteria cells from the air settled in the S-shaped necks' curves. Spontaneous gen did not produce proven cells in the broth.

In complete sentences describe the energy flow between the Sun, the Earth, and space.
evablogger [386]

Answer: The energy from the sun passes through space in the form of invisible waves to the earth surface. It heats up the earth’s surface causing variation in climate.  

Explanation:

The amount of incoming energy from the Sun decides the weather and climate of earth. If the energy that is incoming and outgoing on the earth, then climate is in equilibrium. The balance is depending on the scattering, absorption, reflection and transformation of energy.  

The energy from sun passes through space and reaches the earth’s surface. On reaching surface, the solar energy warms the atmosphere releasing heat energy which gets transferred throughout the planets system by radiation, conduction and convection. Conduction happens in the atmosphere within first several millimeters close to the surface. This heated air expands as it is dense and rises causing transfer of heat to atmosphere through convection process. It results in formation of clouds.

The radiant energy from sun is transmitted via space in form of invisible waves. But much of the suns radiant energy, is transmitted back to atmosphere. The objects on earth like land, plants, animals absorb radiant energy as heat of which one third gets re-radiated back to atmosphere that is absorbed by carbon dioxide and water vapor. The atmosphere radiates heat energy back to earth increasing the earth temperature. This trapping of radiation is greenhouse effect.  

The thermal energy obtained by convection currents are responsible for wind, cloud formation, and weather formation.  The hydrosphere that comprises of 70% of earth’s surface absorbs solar energy.  

On the basis of the above explanation is:  

The energy from the sun passes through space in the form of invisible waves to the earth surface. It heats up the earth’s surface causing variation in climate.

Based on your readings about Bt corn, express your opinion about whether or not farmers should continue planting Bt corn. Explai
miss Akunina [59]
Farmers should discontinue the use of Bt corn (genetically modified maize)as their negative affects on the health of the consumers have not been fully over ruled by the recent research. In my opinion, genetically modified crops, although, are resistant to various pests, should not be encouraged because of the toxic chemical contents used during their production. There's a strong likelihood of these toxic chemicals entering our food chain and also being harmful to other naturally growing plants, hence there's a need for more research before this idea is pursued.
