What Is Starch? Starch is the most important source of carbohydrates in the human diet and accounts for more than 50% of our carbohydrate intake. It occurs in plants in the form of granules, and these are particularly abundant in seeds (especially the cereal grains) and tubers, where they serve as a storage form of … Read more

What is a Pound? A pound is a unit of measuring mass that belongs to the imperial system of units. Pound is commonly used in the United States of America and the United Kingdom as a unit for measurement of mass. Pound can express both force and mass; and is generally abbreviated as ‘lb’ due … Read more

What Is Deliquescence? Deliquescence, the process by which a substance absorbs moisture from the atmosphere until it dissolves in the absorbed water and forms a solution. Deliquescence occurs when the vapour pressure of the solution that is formed is less than the partial pressure of water vapour in the air.  Unlike hygroscopy, however, deliquescence involves absorbing sufficient … Read more

What Is Polyp? Polyp is one of two principal body forms occurring in members of the animal phylum Cnidaria. The polyp may be solitary, as in the sea anemone, or colonial, as in coral, and is sessile (attached to a surface). The upper, or free, end of the body, which is hollow and cylindrical, typically has a mouth surrounded by extensible tentacles that bear … Read more

What Is Catabolism? Catabolism is a metabolic process used for breakdown of complex or large molecules (such as polysaccharides, lipids, nucleic acids and proteins) to simple small molecules (such as monosaccharide, fatty acids, nucleotides and amino acids, respectively). During the catabolism process energy is released from the bonds of the large molecules being broken down. … Read more

What Is Cell Wall/Plasma Membrane? The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment. The cell membrane consists of a lipid bilayer, including cholesterols (a lipid component) that sit between phospholipids to maintain their fluidity at various temperatures. The membrane … Read more

Measurements of physical quantities are expressed in terms of units, which are standardized values. There are two major systems of units used in the world: SI units (also known as the metric system) and English units (also known as the customary or imperial system). English units were historically used in nations once ruled by the British Empire and are still widely used in … Read more

In ecology, Primary Productivity is the rate at which biomass is produced by organisms which converts inorganic substrates into complex organic substances. Biomass is simply the amount of matter that’s stored in the bodies of a group of organisms. Productivity can be defined for any trophic level or other group, and it may take units of either energy or biomass. Primary production … Read more

What are Volts? Volts are the base unit of voltage and measure the potential difference between two points. This unit of electric potential shows the difference in the electrical circuit. It refers to the electrical pressure inside a circuit and is measured in volts. When the volts increase then the current will increase as well.  … Read more

What is galvanisation? Galvanisation or galvanization (or galvanizing as it is most commonly called) is the process of applying a protective zinc coating to iron or steel, to prevent rusting. The most common method is hot dip galvanizing, in which steel sections are submerged in a bath of molten zinc. Galvanization helps extend the life of steel parts by forming … Read more
