Biologically Important Properties of Water

Biological Properties Of Water

 

Best Solvent

 

Water is an excellent solvent for polar substances, when ionic substances dissolved in water, dissociate into positive and negative ions.

 

Non-ionic substances, having charged groups in their molecules, are dispersed in water.

 

Because of solvent property of water, almost all reactions in cells occur in aqueous media.

 

High Heat Capacity

 

Water has great ability of absorbing heat due to its high specific heat capacity.

 

The specific heat capacity of water is the number of calories required to raise the temperature of 1g water

through 1°C.

 

The thermal stability plays an important role in water based protoplasm of individuals metabolic activities.

 

High Heat of Vaporization

 

Liquid water requires higher amount of heat energy to change into vapours due to hydrogen bonding which holds the water molecules together.

 

It provides cooling effect to plants when water is transpired, or to animals when water is respired.

 

Act As Amphoteric Molecule

 

Water molecule acts both as acid and a base. As acid, it gives up electron to form H+ ion, while as a base, it gains electron to form OH ions.

 

H2O <-> H+ + OH-

 

It acts as buffer and prevents changes in the pH of living body.

 

Protection

 

Water is an effective lubricant that provides protection against damage resulting from friction.

Note: Also, those who wish can choose specific curricula and courses, forming “education by order”, which can be obtained faster and cheaper. The diploma of graduating from the university with a distance form of training received legal confirmation, allowing yesterday’s “distance workers” to apply for jobs and leadership positions on an equal basis with graduates of full-time education. Yes, and employers themselves have become much more loyal to the level of knowledge of applicants who have completed the distance learning form. Considering the variant of education with the help of distance technology, it should be taken into account that this type of training has both obvious pluses and obvious disadvantages for students. Distance learning is the main advantage. Higher education is a distant, special form of education, which has a number of advantages over full-time, part-time or evening forms, as well as external studies.
