If a 30% sucrose solution is separated from a 40% sucrose solution by a membrane impermeable to sucrose, in which direction will
Tom [10]

Answer: from 30% sucrose solution to the 40% sucrose solution

Explanation:

From the definition of osmosis is the movement of water molecules through a selectively permeable membrane from a region of lower solute into a region of higher solute concentration, until the solute concentrations on the two sides is equal.

Therefore the net movement of water molecules will move from 30% sucrose solution to the 40% sucrose solution until the concentration of sucrose on both sides of the impermeable membrane is equal 35% each.

Ebstein Barr Virus

The Epstein-Barr virus is a human herpes virus with unusual biological characteristics.

  • It lives in practically every human person in a dormant condition in resting memory B lymphocytes
  • It is also a strong transforming virus in vitro for B cells and is linked to numerous significant lymphomas, including Burkitt's, Hodgkin's disease, and immunoblastic lymphoma.

With the exception of the memory compartment, each stage of the cycle has been shown to be possibly controlled by the immune response.

Epstein-Barr virus (EBV), commonly known as human herpes virus 4, is a double-stranded DNA herpes virus that is extensively spread. It is the cause of infectious mononucleosis.

  • EBV is most usually transmitted by body fluids, particularly saliva. EBV, on the other hand, can transmit by blood and sperm during sexual intercourse, blood transfusions, and organ transplants.

EBV can be transferred by utilizing materials that have recently been used by an infected individual, such as a toothbrush or a drinking glass.

  • The virus is likely to survive on an object for at least as long as it is wet.
  • When you initially get infected with EBV (primary EBV infection), you might spread the virus for weeks or even months before you notice any symptoms.
  • Once the virus has entered your body, it remains dormant.

Hence, the correct answer is option A
