Which end of the water molecule has a slightly positive charge?

• the oxygen end

• the hydrogen ends

• both ends are slightly positive

• neither end is positive

Which properties of water are helpful for aquatic organisms? (3)

• Having a high specific heat capacity stops the temperature of ponds, lakes, and oceans fluctuating too much over a short period of time

• High latent heat of vaporization means ponds, lakes, seas, and oceans don't lose too much water on extremely hot days

• Being a polar molecule allows electric eels to become charged up quicker

• Ice is less dense than liquid water so forms an insulating layer on ponds and polar seas/oceans

• Hydrogen bonds make it easier for fish to swim

• both sides are positive
