     Which of these is the strongest bond  double covalent bond  hydrogen bond  single covalent bond  The main component of the cytosol is ____.  proteins  salts  water  sugars  Which of these molecules uses simple diffusion to pass through the lipid bilayer of the cell membrane?  sodium  water  carbon dioxide glucose  Osmosis is  movement of a substance like potassium down its concentration gradient  movement of water from an area of low H20 concentration to an area of high H20 concentration  movement of water from an area of high H20 concentration to an area of low H20 concentration  consumption of ATP 
  
  Solution
1,The main component of cytosol is -
ans-Water(about 70%)
2.which of these molecules uses simple difusion topass through the lipid bilayer of the cell membrane
ans- Co2
3.osmosis is-
ans-Movement of water from an area of high H2O concentration to an area of low H2O concentration
(During osmosis,solvent moves through a semipermeable membrane from high solvent concentration to low solvent concentration.)
