Answer:
Cell Wall
Explanation:

Explanation:
An ammonia
molecule contains electronegative nitrogen atom. The difference between electronegativity of nitrogen and hydrogen atom is high.
Therefore, nitrogen will attract the shared pair of electrons more towards itself. As a result, there will be partial positive charge on hydrogen and partial negative charge on nitrogen.
Thus, due to these charges
is polar in nature.
Boyle’s law, also referred to as the Boyle-Marriott law, or Mariotte’s law ( especially in France), is experimental gas law that describe how pressure of a gas tends to increase as the volume of the container decreases.
