Answer: This is an example of downregulation and upregulation.
Explanation:
Downregulation is a process in which cells decrease the production of one of their components, responding to an external stimulus. Upregulation, on the other hand, is when cells increase the production of one of their components in response to an external stimulus.
In this case, the decrease in insulin receptors would make the cell less sensitive to the hormone.
If there's a lot of insulin around those cells, the cell would have to decrease its sensitivity, otherwise, it would metabolise more glucose than the body needs. The contrary would happen if there was too little insulin around those cells, they would have to become more sensitive to it by increasing the number of receptors.
Answer:
The potential for r > rb is equal to zero.
Explanation:
For r > rb, the potential is:
Then, the net potential is:
Answer:
t= 2 sec
Explanation:
Given that
Ui= 16 m/s
Vi= 20 m/s
As we know that at the maximum height ,the y component of velocity will become zero.
We know that horizontal component of velocity will remain constant trough out the motion.
We also know that acceleration due to gravity is in downward direction.
Vf= Vi- g t
Now by putting the values
0 = 20 - 10 x t ( take g= 10 m/s²)
20 = 10 t
t= 2 sec
Therefore the answer is 2 sec.
If the north and south pole crosses, radiations can enter Earth's atmosphere easily, continents will lurch in one directions causing natural calamities and species extinction.
<u>Explanation:</u>
- The North and South pole forms the Earth's magnetic field which protects us from harmful radiation entering the atmosphere. If these poles get flipped, a global cataclysm may occur.
- The continents will move to one direction causing massive earthquakes, rapid change of weather and climate and results in species extinction.
- Over the past 150 years, the magnetic poles are casually moving but now it is moving very fast which may result in a flip of the magnetic poles.
- Earth's magnetic field is what shields us from harmful space radiation which can damage cells, causing cancer, and fry electronic circuits and electrical grids. With a weaker field in place, This will disrupt the internal compass and many navigations may get interrupted
