How Is Water Essential For Life
Answers
Explanation:
Water is essential to life—we learn this early in our elementary school years.
This information is often accompanied by the fact that over 50% of our bodies are made up of water.
As I often find, the answer to this question would fill many articles.
This article will focus on three properties of water that make it critical to life and that can be demonstrated with simple classroom experiments.
Water Is “Friendly”
The composition of a water molecule is one of the first chemical compounds we learn—H2O—two hydrogen atoms and one oxygen atom.
The atoms connect in a slightly offset or triangular structure, which creates a positive charge on one side of the molecule and a negative charge on the other.
This unique structure allows a water molecule to “shake hands” with many other molecules, earning it the moniker “the universal solvent.”
This ability is at the heart of many of the functions water performs for living organisms:
water delivers dissolved nutrients to cells
water ferries dissolved waste away from cells
water along with dissolved electrolytes allows electrical signals to travel along the nervous system (see link below for experiment that demonstrates salt water’s capacity to carry an electrical charge)
Answer:
(1) All cellular processes occur due to water.
(2) Transportation of substances in our body takes place by dissolving in water.
(3) Terrestrial animals require fresh water for transportation of minerals and for getting rid of waste from their body.
