 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)

 Reproductive systems The reproductive system in both males and females consists of structures that produce reproductive cells, or gametes, and secrete sex hormones. A gamete is a haploid cell that combines with another haploid gamete during fertilization. Sex hormones are chemical messengers that control sexual development and reproduction. The male reproductive system consists … Read more Reproductive Systems

 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. For … Read more Digital Divide & Its Prevention (1)

So washing soda is hydrated salt of sodium carbonate containing 10 molecules of water of crystallization. Sodium carbonate is manufactured by Solvay process. The manufacture of sodium carbonate by Solvay … Read more Methods Of Production And Manufacturing

 Importance of Science & Technology as an engine for national development- Industrial development & Urbanization Professor Freeman J. Dyson, of Institute of Advanced Studies, Princeton, in his book “Infinite in all Directions,” had this to say about Technology: “Technology is a gift of God. After the gift of Life, it is perhaps the … Read more Importance Of Science & Technology As An Engine For National Development Industrial Development & Urbanization (1)

 Harmful plants They may look harmless enough, but plants can harbor some of the most deadly poisons known. From the death of Socrates by poison hemlock to the accidental ingestion of deadly nightshade by children, poisonous plants have been responsible for human deaths throughout history. Get to know some of the most infamous … Read more Harmful Plants

 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

 Defluoridation and other Techniques of water purification Defluoridation Defluoridation is the downward adjustment of the level of fluoride in drinking water. Worldwide, fluoride is one of the most abundant anions present in groundwater. Fluoride is more present in groundwater than surface water mainly due to the leaching of minerals. Groundwater accounts for 98 … Read more Defluoridation And Other Techniques Of Water Purification

 Electric discharge in gases Electrical discharge through gases is studied by using a specially designed glass tube commonly called as a discharge tube. It consists of a cylindrical glass tube having a side tube, and two metallic electrodes one at each end. These electrodes can be connected to the respective terminals of a … Read more Electric Discharge In Gases
