Here in the given options, Sodium (Na) combines with Chlorine (Cl) to form a more complex single product Sodium Chloride (NaCl).

Ans. Let radius of the base and height of the cone be ‘r’ & ‘h’ respectively.

Then volume of cone = πr2h/3 For cylinder, radius is reduced by 4 times = r/4 And,  height is increased by 8 folds = 8h Volume of cylinder = πR2H = π(r/4)2 (8h) = (16/8)πr2h = πr2h/2 Ratio of volume of cone to volume of cylinder = (πr2h/3) : (πr2h/2) Or, Ratio = 2 : 3.

There are 3 stages in cellular respiration. They are:

1. Glycolysis

2. Kreb's cycle

3. Electron transport chain

Here, Glycolysis produces only 2 ATP whereas Kreb's cycle produces no ATP. Electron transport chain of the cellular respiration produces the maximum ATP.
