Digestive System

Digestive System Introduction The respiratory and circulatory systems work together to provide cells with the oxygen they need for cellular respiration. Cells also need glucose for cellular respiration. Glucose is a simple sugar that comes from the food we eat. To get glucose from food, digestion must occur. This process is carried out by the … Read more Digestive System

moving charge and magnetism

Moving Charge and Magnetism Magnetism is a phenomenon produced by the motion of electric charge, which results in attractive and repulsive forces between objects. A magnet is any piece of material that has the property of attracting iron (or steel). Magnetite, also known as lodestone, is a naturally occurring rock that is a magnet. This … Read more moving charge and magnetism

Malnutrition

WHO Defines Malnutrition as “Malnutrition refers to deficiencies, excesses, or imbalances in a person’s intake of energy and/or nutrients. The term malnutrition addresses 3 broad groups of conditions: undernutrition, which includes wasting (low weight-for-height), stunting (low height-for-age) and underweight (low weight-for-age); micronutrient-related malnutrition, which includes micronutrient deficiencies (a lack of important vitamins and minerals) or … Read more Malnutrition

electro chemistry

Electrochemistry Electrochemistry is the study of production of electricity from energy released during spontaneous reactions and the use of electrical energy to bring about non-spontaneous chemical transformations. Electrochemistry is the study of chemical processes that cause electrons to move. This movement of electrons is called electricity, which can be generated by movements of electrons from … Read more electro chemistry

equilibriums

Chemical equilibrium Chemical equilibrium is a state in which the rates of the forward and reverse reactions are equal and the concentrations of the reactants and products remain constant. Equilibrium is a dynamic process i.e. the conversions of reactants to products and products to reactants are still going on, although there is no net change … Read more equilibriums

Motion, laws of motion

Motion Motion is a change in position of an object with respect to time. Motion is typically described in terms of displacement, distance, velocity, acceleration, time and speed. The branch of physics which deals with the study of motion of material objects is called mechanics. Mechanics is divided into following branches. (i) Statics : Statics … Read more Motion, laws of motion

Scarcity of water, methods of conservation-rain water harvesting and watershed management, ground water management

  Scarcity of water   Water scarcity is possibly to pose the greatest challenge on account of its increased demand coupled with shrinking supplies due to over utilisation and pollution. Water is a cyclic resource with abundant supplies on the globe. Approximately, 71 per cent of the earth’s surface is covered with it but fresh … Read more Scarcity of water, methods of conservation-rain water harvesting and watershed management, ground water management

use of information technology in administration

Use of information technology in administration Public Administration, governed by bureaucratic structures built on rationale principles, that dominated the twentieth century, has failed to respond to the changing requirements of the present times. It is so because it tended to be rigid, laid too much emphasis on red-tapism; sap creativity; thwarted initiative; wore out dynamism … Read more use of information technology in administration
