What Is Monoalphabetic Cipher? Monoalphabetic cipher is one where each character of a plain text is mapped to a fixed other character of cipher text. Examples of monoalphabetic ciphers would include the Caesar-shift cipher, where each letter is shifted based on a numeric key, and the atbash cipher, where each letter is mapped to the … Read more
Taproot is the main root of a primary root system, growing vertically downwards, from which other roots sprout out laterally. Taproot develops from the radicle of a seed, forming the primary roots, which in turn branch to form tertiary roots. These may further branch to form rootlets. For most plant species, the radical dies some … Read more
Get to understand the clear distinction between Streptococcus and staphylococcus bacteria. The basis of distinction include: shape, areas of infection, pathogenic species, areas of infection, division, catalase test, pathogenesis, treatment options and more important, the similarities. The difference Shape Staphylococcus bacteria has multiple axes cellular division, which results in its grape-like shape (spherical cells in … Read more
Get to understand the clear distinction between polysaccharide, monosaccharide and disaccharide. The basis on distinction include: Description, Classification, solubility, Taste, chemical structure, molecular weight and Examples. Key Differences Description Polysaccharides are polymeric carbohydrate molecules composed of long chains of monosaccharide units bounded together by glycosidic bonds. A disaccharide also known as double sugar or bivose, … Read more
What is Xylem? Xylem vessels are hollow cells arranged end to end and joined by perforation plates to form continuous tubes. In these cells both nucleus and cytoplasm are absent. The end walls of these cells are often completely broken to form a long distance channel for transport of water. The main function of xylem … Read more
Polymers are linearly chained large molecules composed of sequences of repeating monomer units connected by covalent bonds. Polymers can be classified as organic or inorganic polymers. Polymer as a chemical compound has high molecular weight consisting of a number of structural units linked together by covalent bonds. (A structural unit is a group having two … Read more
A chemical compound is made up of two or more elements that are chemically bonded together. One of the ways to classify compounds is by identifying them as either organic or inorganic. The main difference that lies between these organic compounds and inorganic compounds is that organic compounds always have a carbon atom while most of the … Read more
Moyoglobin is an iron and oxygen-binding protein found in the muscle tissue of vertebrates in general and in almost all mammals. Myoglobin has a very high affinity for oxygen and acts as an oxygen molecule. It only releases oxygen when the partial pressure of oxygen has fallen drastically. Hemoglobin on the other hand is the … Read more
