 Reproduction and growth – type of reproduction Living things grow and they reproduce. Growth is a way to generate the materials for reproduction. Reproduction is a way to make new organisms that can grow. Thus, the apparent “goal” of every organism is to fill the available world with its offspring, that is, with … Read more Reproduction And Growth

 Flood and Drought Occurrence Drought Drought is a complex, slow-onset phenomenon of ecological challenge that affects people more than any other natural hazards by causing serious economic, social and environmental losses in both developing and developed countries. The period of unusual dryness (i.e. drought) is a normal feature of the climate and weather … Read more Flood And Drought Occurance

 Osmoregulation Osmoregulation is the process of maintaining salt and water balance (osmotic balance) across membranes within the body. The fluids inside and surrounding cells are composed of water, electrolytes, and nonelectrolytes. An electrolyte is a compound that dissociates into ions when dissolved in water. A nonelectrolyte, in contrast, does not dissociate into ions … Read more Osmoregulation

 Electro magnetic induction When a DC current passes through a long straight conductor a magnetising force, H and a static magnetic field, B is developed around it If the wire is then wound into a coil, the magnetic field is greatly intensified producing a static magnetic field around itself forming the shape of … Read more Electro Magnetic Induction

 Role of drdo in various fields (other than weapons) The Defence Research and Development Organisation (DRDO) is an agency of the Republic of India, charged with the military’s research and development, headquartered in New Delhi, India. It was formed in 1958 by the merger of the Technical Development Establishment and the Directorate of … Read more Role Of Drdo In Various Fields

 Respiratory quotient: Carbohydrates, fats and protein The respiratory quotient (or RQ or respiratory coefficient), is a dimensionless number used in calculations of basal metabolic rate (BMR) when estimated from carbon dioxide production. It is calculated from the ratio of carbon dioxide produced by the body to oxygen consumed by the body. Such measurements, … Read more Respiratory Quotien1

 Ray optics Nature of light Light is a transverse, electromagnetic wave that can be seen by humans. The wave nature of light was first illustrated through experiments on diffraction and interference. Like all electromagnetic waves, light can travel through a vacuum. The transverse nature of light can be demonstrated through polarization. Light is … Read more Light

 Chromosomes Chromosome, the microscopic threadlike part of the cell that carries hereditary information in the form of genes. A defining feature of any chromosome is its compactness. For instance, the 46 chromosomes found in human cells have a combined length of 200 nm (1 nm = 10− 9 metre); if the chromosomes were … Read more Chromosomes

 Allotropes of carbon Allotropy is the property of some chemical elements to exist in two or more different forms, or allotropes, when found in nature. There are several allotropes of carbon. Diamond Diamond is probably the most well known carbon allotrope. The carbon atoms are arranged in a lattice, which is a variation … Read more Allotropes Of Carbon
