 Factors affecting photosynthesis Light  Without light, a plant cannot photosynthesize very quickly, regardless of whether there are water and CO2 or not. But overdoing light is also not a good idea. In nature, balance is crucial. But increasing the intensity of light to a prudent limit will speed up the process. Carbon Dioxide … Read more Factors Affecting Photosynthesis (2)

 Refraction of light Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another.  This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows. Even our eyes depend upon this bending of light. … Read more Refraction Of Light

 Digital divide & its prevention Digital technologies have spread rapidly in much of the world. Digital dividends—the broader development benefits from using these technologies have lagged behind. In many instances digital technologies have boosted growth, expanded opportunities, and improved service delivery. Yet their aggregate impact has fallen short and is unevenly distributed.

 Electricity and its effects -electric intensity, potential, potential difference Electricity is the physical flow of electrons, referred to as an electrical current. Electricity is an energy carrier that efficiently delivers the energy found in primary sources to end users, who in turn convert it into energy services. Electricity can be created in three … Read more Electricity And Its Effect1

 Technology with a Human Face Technology and the Human Race The human race has indeed gone far with technology. From the age when he still used wooden and stone tools to a powerful era of silicon and steel, he ceased to be a helpless prey to a number of predators to become a … Read more Technology With A Human Face (1)
