During the early stages when Andrew was a child there will be as such no effect of the virus in the brain.
During the early stage the virus will remain in the brain and cause harm in the later days when Andrew will be older.The virus can alter the brain functions such as homeostasis, blood brain barrier functions.It enters the brain while damaging the nervous system.
The process of osmosis is the movement of water through a selectively permeable membrane from an area of higher concentration to an area of lower concentration.
If 1% sugar solution is placed in pure water, then there would be a higher concentration of water molecules outside the cell compared to inside the cell. The solution outside the cell would be hypo-tonic (containing fewer solute molecules than inside the cell). Water will move into the cell by inward osmosis and the cell would then swell.

Answer: Coenzymes
Explanation:
Coenzymes are the small organic molecules that are often derived from the vitamins. It can be tightly or loosely bond to the enzymes.
Tighly bond ones are the prothestic groups and loosely bond ones are coenzymes like the products and substrate which binds to the enzyme and get released from it.
This component is very important for any reaction to take place. It bonds to the enzymes and helps in product formation.
