All you have to do is freeze water to make it hard.
Most polar animals are coloured in some form of black and/or white. The black sides of animals make them hard to see from above -- in water, and the white sides of animals make them hard to see from below -- in water. Most animals that exist in polar environments find their food chains in water, so their camouflage colouring helps them survive. Examples are puffins, penguins and polar bears.
Yes, but they might not be the SAME water molecules. Life (chlorophyll) splits water and animals make water from its components.
People are "animals". Animals can not make their own food they have to eat other animals and or plants to survive. Plants can make their own food (from air, water and sunlight) - they are the basis of all food - without plants there could be no animals.
LN2 other know as liquid nitrogen is a solution that can make water hard
Why is life so hard? just to guess
hard water can be converted to soft water by boiling, filteration etc.
Fresh water is vital because it is the source of life. We drink it, we wash in it, we use it to grow plants which we make into food. It is useful to keeping humans, animals and plant life alive!
Ground oyster shells will make soft water harder. Therefore, it will make hard water, harder.
