Many peculiar properties of water depends on the fact that the water molecule is polar.
The specific water behavior depends on the fact that one water molecule establish the so called hydrogen bond, possible due to polarity, with four nearby molecules . In particular the oxygen atom is bonded with two hydrogen atoms of other molecules, while the two hydrogen atoms are bonded to other two molecules at the oxygen terminal. This due to the residual positive charge of the hydrogen part and negative residual charge of the oxygen.
This set of weak bonds causes, for example, the fact that, at atmospheric pressure , water density is at maximum at 4 °C when water is liquid while the density of ice (solid water) is greater.
Moreover, the polarity of water renders it a very good solvent. As a matter of fact, when another polar material enters in water, water molecules substitute the polar bonds maintaining the material in solid state surrounding the atoms or the molecules with a water molecules layer (called hydration layer) so to decrease the energy of the solution and render it stable.
Last, but not least, the water polarity causes that hydroxyl and hydrogen ions move in water when an electrical field is present (during electrophoresis) by exchanging electrons with water molecules more than by simple push of the electrical field, having much higher mobility with respect to other ions.

How is water's polarity helpful to living organisms?
Water's polarity allows it to form hydrogen bonds with other water molecules and with charged molecules like ions. This property enables water to dissolve essential nutrients and facilitate various biochemical reactions in living organisms. Additionally, water's polarity contributes to its high surface tension, which is important for processes like water transport in plants and the maintenance of cell structure.
Why is it important to classify living things and non living things?
Classifying living and non-living things helps us understand the world around us, identify relationships between organisms, and make predictions about behaviors and characteristics based on their classification. It also helps in organizing information, studying evolution, and developing strategies for conservation and biodiversity.
What characteristic of living things distinguishes them from non-living things?
The characteristic that distinguishes living things from non-living things is the ability to grow, reproduce, and respond to stimuli.
What are the seven life processes of living thing?
It is easy to decide whether most objects are living or not. A brick is obviously not living and has never been alive. A dog running around is obviously alive. But what about a leaf that has fallen from a tree? To answer a question like this we need to think about what all living things must do to be alive. All living things must carry out seven processes to stay alive. 1. All living things obtain energy from their food by a process called RESPIRATION. 2. All living things obtain food by a process called NUTRITION. 3. All living things rid themselves of waste materials by a process called EXCRETION. 4. GROWTH is another important function of living things. All living things grow. 5. All living things respond to their environment. They therefore require SENSITIVITY. 6. All living things move. MOVEMENT is an important part of life. 7. All living things get old and die. Replacements are made by the process of REPRODUCTION. Remember it as MRS GREN
Do living things need ultraviolet light?
Some living things, like plants, require some exposure to ultraviolet (UV) light for processes like photosynthesis. However, excessive UV light can be harmful and cause damage to living organisms, including humans, by harming DNA. It is important for living things to have a balance of UV light exposure to maintain health and growth.
Why are bones important to living things?
bones are important to living things because it protects plants
What factor is the most important to living things?
Oxygen is the most important factor for living things.
Why is ozone in the stratospere important for living things?
The ozone in stratosphere is important for living things. The living things cannot expose themselves to UV which ozone protects.
Why is ozone gas important to the earth's living things?
Ozone gas is important for living things. It maintains our biosphere.
What is important to most living things?
Water because most living things depend on it.
Why is water good for living things?
All living things need water because they need to obtain chemicals from their surroundings, break down food, grow, move substances within their bodies, and reproduce.
Are beagles important?
Yes. All living things are important.
What is One important difference between living things and non living things is that only living things have?
One important difference between living things and non-living things is that only living things have the ability to grow, reproduce, and respond to stimuli from their environment. Living organisms maintain homeostasis, utilize energy, and undergo metabolic processes to sustain life. In contrast, non-living things do not exhibit these biological functions or processes.
How is chemistry important for the study of living things?
All around us, living things or inorganic things are chemical compounds.
Why are minerals important for living things?
