Asap i really need with these three questions fast.
how is polarity important to life?
how is expansion upon freezing important to life?
how is versatility as a solvent important to life?

1.Water's polarity allows it to dissolve other polar substances  easily. When a polar substance is put in water, the positive ends of its molecules are attracted to the negative ends of the water molecules, and vice versa. ... The dissolving power of water is very important for life on Earth.2.The expansion of water upon freezing is vital to life on Earth. It is what causes ice to be less dense as a solid than as a liquid. This means that ice floats in liquid water. Water freezes when its molecules are no longer moving around enough to break their hydrogen bonds.3.Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. Also, water is called the "universal solvent" because it dissolves more substances than any other liquid. This is important to every living thing on earth.
