AIDS is one disease caused by a virus infection. The virus attacks immune system cells known as T cells.
VLD [36.1K]

Answer:

yes,its true

Explanation:

I just want to say first off

the immune cell known as T cell also known as white blood cells

Since the first main attack from the bodies response against a virus is deploying T cells to attack

CD4 cells are the basic T cells and HIV virus which is AIDS will start to "Eat itself inside" Ofc not they will use protein spikes to form their way in

they start to create copies of themselves inside the T cell itself and creating a new protein called Env to form their ways in ofc

They are able to bypass CD4 cells is because its a basic cellular receptor for T cells making them really deadly

They now will start to attack other white cells and deploying more and more of their virus cells

  • The alkanes are immiscible in water but freely miscible in other non-polar solvent .
  • The alkanes are consisting of weak dipole dipole bonds can not breaks the strong hydrogen bond.
  • The alkanes having only carbon (C) and hydrogen (H) atom which is bonded by a single bonds only.
  • The alkanes posses weak force of attraction that is weak van der waals force of attraction.

The ethane, propane, butane, belong to alkanes family.The alkanes are also considers as saturated hudrocarbons. Ethane is found in gaseous stae Ethane is the second alkane followed by propane followed by butane.
