The hydrogen, oxygen, and carbon atoms in a glucose molecule are held together by insert symbol character

Atoms  in  glucose  molecules  are   held   together  by  Hydrogen   bond.  This  is  a  tiny   force  that hold  glucose  together  and  a  chain  in  closely.Despite hydrogen  bond  been  weak  the  molecules  is  stable  when  many  of  the  hydrogen  bond  is  formed  between  cellulose  molecules.  This  is  a  very  strong   complex  that  has  enormous  strength.

The correct answer is c

The density of water is 1 g/cm cubed and in order for the pebble to sink its density has to be greater than the density of water and in order for the twig to float its density has to be less than the density of water
