How does the amount of water affect the growth of bean plants
Explanation:
The reason for that is because the only thing that differed in size or amount is the water. According to the question every other component, soil and amount of sunlight, are equal and the only thing not evenly distributed between the pots is the amount of water.
Polarity affects hydrogen bonding because hydrogen bonding occurs due to a bond being polar. One side of the bond will be slightly more negative because it's pulling more electrons towards itself and the other side of the bond will be more positive. Therefore the partially positive bond of one molecule will be attracted to the partially negative bond of another molecule. This is called an intermolecular force and hydrogen bonds are the strongest intermolecular force.
