Introduction Organic evolution refers to the slow and gradual process by which living organisms have changed from the simplest unicellular form to the most complex multi-cellular forms that are existing today. Organic evolution primarily involves modifications in the existing organisms and the inheritance of these modifications.Biological evolution is genetic change in a population from one

Alkalinity and Acidity Alkalinity and Acidity are measured using a scale of numbers from 0 to 10 called the pH scale. A solution with pH value of 7 is neutral. A solution with a pH value less than 7 is acidic while a solution with pH value greater than 7 is alkaline. Acidity increases with decreasing

Introduction A salt is an ionic compound formed when the hydrogen of an acid is partly or completely replaced by a metal ion or ammonium ion. All salts are chemically and electrically neutral. Example: Diagram above shows that when the hydrogen ion in nitric acid is replaced by Na+, Ca2+, NH4+ or Al3+ ions, salts

Rational Numbers We can write numbers such as 8, 4½, 1/5, 0.211, √49/16, 0.3 as exact fractions or ratios: 8/1, 9/2, 1/5, 211/1 000, 7/4, 1/3. Such numbers are called rational numbers. Numbers which cannot be written as exact fractions are called non-fractional numbers, or irrational numbers. √7 is an example of a non-rational number.

Introduction A measure of central tendency is a single value that attempts to describe a set of data by identifying the central position within that set of data. As such, measures of central tendency are sometimes called measures of central location. They are also classed as summary statistics. The mean (often called the average) is
