At present, loss of specific species, groups of species (extinction) or decrease in number of particular organisms (endangerment) are taking place in different parts of the world at a rapid pace. These losses are often manifestations of degradation or destruction in the ecosystem or habitat. DNA Banks More plant conservationists are turning to DNA technologies … Read more
Hydrogen bombs are thermonuclearweapons which employs fusion of isotopes ofhydrogen. The result is greatly increased explosivepower when compared to single-stage fissionweapons.The energy released in a Hydrogen bombis several magnitudes higher than anAtom bomb. A fusion bomb is more sophisticated anddifficult to make, since it requires a muchhigher temperature — in the order ofmillions of degrees … Read more
Allogamy Allogamy occurs when the gametes which join together during fertilization come from two different individuals. The female gamete is usually in the form of an egg or ovum while the male gamete takes the form of a sperm. Both egg and sperm are cells specialized to perform the task of reproduction; each sex cell … Read more
Composting is an anaerobic microbially driven process that converts organic wastes into stable sanitary humus like material. This material can then be safely returned to the natural environment. This method is actually a low moisture, solid substrate fermentation process. In large- scale operations using largely domestic solid wastes, the final product is mostly used for … Read more
Symbiosis is a close ecological relationship or association between the individuals of two (or more than two) different species. In symbiosis, at least one member of the pair benefits from the relationship. The other member may be injured (parasitism, relatively unaffected (commensalism), may also benefit (mutualism). In other words, at least one member of the … Read more
Ultraviolet (UV) disinfection systems contact the treated secondary wastewater with UV light bulbs that are encased in clear housings. The UV light kills pathogenic organisms by using a germicidal photochemical wavelength. Unlike chlorination, UV leaves no residual in the wastewater with which to be concerned. Plants that use UV must either have dual UV systems … Read more
