What Is Molecule? A molecule can be described as two or more atoms of the same or different element that are bound together by chemical bonds. Each atom carries a certain number of electrons that orbit around nucleus. A molecule may be homonuclear, which means, it consist of atoms of one chemical element as with … Read more
What Is Nitrification? In this process, the ammonia is converted into nitrate by the presence of bacteria in the soil. Nitrites are formed by the oxidation of Ammonia with the help of Nitrosomonas bacterium species. Later, the produced nitrites are converted into nitrates by Nitrobacter. This conversion is very important as ammonia gas is toxic for plants. … Read more
What Is An Element? An element is a pure substance that cannot be decomposed into simpler substances by ordinary chemical processes. Although elements cannot be changed by chemical reactions, new elements may be formed by nuclear reactions. Elements are defined by the number of protons they posses. Atoms of an element all have the same … Read more

Plasmodium vivax Plasmodium vivax is a protozoalparasite and a human pathogen. This parasite is the most frequent and widely distributed cause of recurring malaria. Although it is less virulent than Plasmodium falciparum, the deadliest of the five human malaria parasites, P. vivax malaria infections can lead to severe disease and death, often due to splenomegaly (a pathologically enlarged spleen). P. vivax is carried by the female Anopheles mosquito. P. vivax are … Read more
What Is Plasticizer? Any substance added to a polymer material that can increase the plasticity of a polymer is referred to as a plasticizer. Plasticizers make plastics elastic, extensible, flexible and plastic at low temperatures. Plasticizers are produced by reaction of an alcohol with an acid such as adipic acid, phthalic anhydride and so forth. … Read more
What Is Star Connection? In star connection, one end of all the three wires are connected to a common point in the shape of Y, such that all the three ends of the three wires form the three phases and the common point forms the neutral. Star connection is preferred for long distance power transmission … Read more
Grafting and budding are horticultural techniques used to join parts from two or more plants so that they appear to grow as a single plant. Grafting and budding are the most widely used vegetative propagation methods. In grafting, the upper part (scion) of the plant grows on the root system (rootstock) of another plant whereas … Read more
What Are Biceps? The biceps branchii commonly referred to as biceps is located in the anterior compartment of the arm. The biceps muscles run from the front of the shoulders to the elbow. It works across three joints and is able to generate movements in glenohumeral (shoulder), elbow and radio-ulnar joints. The biceps are responsible … Read more
