Buffers

This is a compond which behave in such a way so as to resist changes in pH on dilution or addition of moderate amount of acid or alkaline. Sometimes two or more compounds react to form a buffer system.

Sodium bicarbonate act as a buffer by combining with free hydrogen ion. On the other hand, if the alkalinity is increased, it can react with the free hydroxyl ion to form carbonate ions and water. This Sodium bicarbonate can resist either a decrease or increase in pH by mopping up the hydrogen ion or hydroxyl ion.

Processing of animal products

The udders should be washed prior to milking in order to reduce the risk of contamination of the milk. Once milk is collected from the animals through a milking machine, the t...

problem of plant living in fresh water habitat

Buoyancy The density of fresh water is considerably less than that of the sea and such floatation is a greater problem for fresh water plankton. There is occasional flooding which submerges the plants.  The water lilies, water lettuce, water hyacinth are able to stay afloat because of the air spaces in the lower part of the leaves as well as in the skins and roots.

The Nucleic Acids

These are molecules that are essential to and characteristic of life on earth. They form the genetic material of all living organisms including the simplest virus. These compunds are found mainly in the nucleus.  They are DNA (Deoxyribonucleic acid) and RNA (Ribonucleic acid). Nucleic acids have the same basic structure  in all organisms.  Excerpts from the book a glance at cell biology by Ukponmwan Ifueko Oghogho Available @  https://www.morebooks.de/gb/search?utf8=%E2%9C%93&q=Ukponmwan+ifueko+oghogho+ amazon.com/author/ifuekoukponmwan
