Calculation of Mean, Median and Mode of Ungrouped Data Mean, median, and mode are three basic ways to look at the value of a set of numbers. You will start by learning about the mean. The mean, often called the average, of a numerical set of data, is simply the sum of the data values divided

Introduction to Organic Chemistry – Hydrocarbons Organic chemistry originally meant the chemistry of compounds obtainable from plants and animals – living organisms. Organic chemistry is that branch of chemistry that deals with the structure, properties, and reactions of compounds that contain carbon. In other word, organic chemistry is defined as the chemistry of carbon compounds.

Introduction There are no special respiratory organs in unicellular and aquatic organisms such as Amoeba and Paramecium. Oxygen that dissolves in water diffuses into the body while carbon dioxide goes out of the body through the entire body surface. The cell membrane acts as the respiratory surface. The concentration of oxygen in water is higher

Definition of Environmental Physiology This can be defined as effects of the environment on the growth and performance of farm animals. Normal growth and performance are enhanced when climatic factors like temperature, rainfall, wind, relative humidity, sunlight etc. are moderate. Effects of Changes in Climate on Growth High intensity of radiation affect food intake of

Magnifiers Perhaps the simplest optical instrument is the lens magnifier. Without optical aid, we cannot “see” things close up. The eye will simply not focus closer than about 0.25 m (unless you are nearsighted!). But an object places just inside the focal point of a converging lens will produce a large virtual image that can
