Answer:
D. high fever and sore throat
Explanation:
Human herpesvirus 4 is also known as the Epstein-Barr virus (EBV). Human herpesvirus 4 causes infectious mononucleosis (mono). The virus multiplies first in the epithelial cells and then the released progeny infects the memory B cells. The disease is manifested by sore throat and fever. The fever is mild for the whole day but peaks during the early hours of the evening.
<span> They are unable to pass through the plasma membrane and have different methods of action. They attach to their receptors in the target cell surface and influence activity within the cell through cytoplasmic intermediates called second messengers. </span>
<span>The two most important messengers are cAMP and inositol triphosphate. </span>
<span>Cyclic AMP: ATP is converted into cAMP after a series of reactions on the plasma membrane following the attachment of the hormone to the membrane. cAMP relays the signal from the membrane to the metabolic machinery of the cytoplasm. </span>
<span>Inositol Triphosphate: Involves the use of Ca+2 that regulates cellular protein activity.

Answer:
A whole lot of zig-zagging: Perhaps that is what happens when the universe's mysterious dark matter particles hit the Earth. ... Dark matter particles can penetrate all other forms of matter, which means that they may even be able to traverse right through our planet without losing any energy whatsoever.
Explanation:
Answer:
Option (c) is the correct answer.
Explanation:
It is known that if we have to convert temperature from kelvin to degree celsius then we have to subtract 273 from the given value of temperature.
Whereas when we have to convert temperature from degree celsius to kelvin then we have to add 273 in the given value of temperature.
Therefore, convert value of 200 Kelvin in the Celsius scale of temperature as follows.
Temperature = (200 - 273) degree celsius
= - 73 degree celsius
Thus, we can conclude that value of 200 Kelvin in the Celsius scale of temperature is - 73^{o}C.
