Introduction to Nervous Coordination and Integration
Introduction - Animals are different from plants because of their ability of locomotion. This ability probably developed as they have to search for food, unlike the plants that are autotrophic. Since they move from place to place, the animals have to continuously encounter changes in thei..
Physical World and Measurement Introduction
Introduction - Humans have always been curious about the world around them. The world has an astonishing variety of materials and bewildering diversity of life and behaviour. The inquiring and imaginative human mind has responded to the wonder and awe of nature in different ways. This hum..
First Law of Thermodynamics Introduction
Introduction - The branch of chemistry, which deals with energy changes during various physical processes and chemical reactions, is called chemical energetics. All chemical reactions are normally accompanied by energy changes. These energy changes take place because energy is needed to b..
