 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

Nuclear retaliation to a first strike … Read more

 Magnetic storm A magnetic storm is a period of rapid magnetic field variation. It can last from hours to days.  Magnetic storms have two basic causes:   The Sun sometimes emits a strong surge of solar wind called a coronal mass ejection. This gust of solar wind disturbs the outer part of the … Read more

 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

 Fungi fungi, any of about 99,000 known species of organisms of the kingdom Fungi, which includes the yeasts, rusts, smuts, mildews, molds, and mushrooms. There are also many funguslike organisms, including slime molds and oomycetes (water molds), that do not belong to kingdom Fungi but are often called fungi. Many of these funguslike … Read more

 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

 Methods of preparing magnets Some magnets can be created using any of the following ways below.   Induction   Stroking   Using electricity   Since these magnets can be made, they are usually referred to as temporary magnets. Electromagnets are magnets made using electricity and so are called temporary magnet since they only … Read more

 Microbiology Microbiology is the study of microbes or the living organisms that are too small to be visible with the naked eye. These living things can be seen only with the use of a microscope. These life forms are called microorganisms or microbes. Microorganisms include bacteria, archaea, viruses, protozoa, microscopic fungi and yeasts, … Read more

 Magnetic keepers A magnet keeper, also known historically as an armature, is a ferromagnetic bar made from soft iron or steel, which is placed across the poles of a permanent magnet to help preserve the strength of the magnet by completing the magnetic circuit; it is important for magnets that have a low … Read more
