What Is Enantiomers? An Enantiomer is one of the two molecules (stereoisomers) that are mirror images of each other and are non-superposable. Enantiomers have identical chemical and physical properties such as boiling point, melting point and spectroscopic features except for their ability to rotate plane-polarized by equal amounts but in opposite directions. Enantiomers interact differently … Read more
Cryptogams A cryptogam is a plant that reproduces by spores without flowers or seeds. The best-known groups of cryptogams are algae, lichens, Hornworts, Liverworts, mosses and ferns. It also includes non-photosynthetic organisms traditionally classified as plants, such as fungi, slime molds and bacteria. Characteristics Of Cryptogams Phanerogams Phanerogams are plants comprising those having reproductive organs, … Read more
Stereoisomers are pairs of compounds that have the same chemical formula and the same atom connectivity, but they differ in their three-dimensional orientation. Monosaccharide like glucose, fructose, mannose and galactose can show different isomerism. For example glucose and fructose are functional isomers of each other as glucose contains aldehyde group and fructose contains ketonic group … Read more
Permanent magnets and electromagnets are two main types of magnets. A permanent magnet is called a permanent magnet because of ability to generate and retain its own persistent magnetic field. An electromagnet on the other hand is made from a coil of wire wrapped around a ferrous core and requires an electric current to generate … Read more
What Is Tension? Tension is described as the pulling force transmitted axially by the means of a string, a cable, chain or similar one-dimensional continuous object or by each end of a rod, truss member or similar three-dimensional object; tension might also be described as action-reaction pair of forces acting at each end of said … Read more
In digital logic and computing, a counter is a device which stores and sometimes displays the number of times a particular event or process has occurred, often in relation to a clock. The most common type is a sequential digital logic circuit with an input line referred to as the clock and multiple output lines. … Read more
What Are Biodegradable Substances/Waste? Biodegradable substance is a form of substance originating naturally from plant or animal sources, which may be broken down into carbon dioxide, water, methane or simple organic molecules by action of bacteria, fungi and other living organisms by composting, aerobic digestion, anaerobic digestion or similar processes. Biodegradable substances upon braking up … Read more
Most multi-cellular organisms require a mechanism for transporting nutrients throughout their bodies and for removal of waste products. The circulatory system has evolved over time from simple diffusion through cells, in the early evolution of animals, to a complex network of blood vessels that reach all parts of the human body. This extensive network supplies … Read more
Many animals, including humans have two types of chromosomes: Autosomes and sex chromosomes. Sex chromosomes are those that are needed for determining sex (male or female) of an individual. Autosomes are all the rest of the chromosomes that are not needed for sex determination. What Is Autosome? Autosomes are chromosomes that do not carry any … Read more
Disinfection and disinfection are the two common types of decontamination. Decontamination is the process of decreasing antimicrobial presence in an area or on a surface. Sterilization is the process of removing all harmful microorganisms from objects and surfaces whereas disinfection means to eliminate most harmful microorganisms, but this doesn’t include spores. Both procedures (disinfection and … Read more
