Why would a drug that damages capsules help treat a viral infection
ss7ja [257]

Drug that demages capsule is used to treat viral infection because Curing a viral infection  antibiotics are useless against viral infections. This is because viruses are so simple that they use their host cells to perform their activities for them. So antiviral drugs work differently to antibiotics, by interfering with the viral enzymes instead.  

Antiviral drugs are currently only effective against a few viral diseases, such as influenza, herpes, hepatitis B and C and HIV – but research is ongoing. A naturally occurring protein, called interferon (which the body produces to help fight viral infections), can now be produced in the laboratory and is used to treat hepatitis C infections.

thousands of years

Explanation:

A delta the size of the Mississippi River will take several thousand of years to form because the process of formation of a delta is geologically controlled.

A delta is a place where  river enters or drains into the sea with many mouth or outlets.

Deltas are depositional terrain full of dis-tributaries.

  • For a delta to form, a terrain must be close to the mouth of an ocean or a larger body of water.
  • The entering stream must be large enough and have large amount of sediment.
  • The river mouth must have been cut to the same level with that of the drainage basin.
  • Most rivers such terrain should be at their lower course where they flow with very low velocity.
  • Wave action should be minimal along such coasts.

These processes takes several thousands of years if not millions.
