Amwoga Khalwale What Is A Colloid? A colloid is a homogenous non-crystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance. A common method of classifying colloids is based on the phase of the dispersed substance and what phase it is dispersed in. Colloids include: gels, sols, aerosols and emulsions. … Read more
While both belong to the Enterobacteriaceae family, Salmonella and Shigella harbor distinctive characteristics that set them apart in terms of transmission, symptoms, and epidemiology. Characteristics of Salmonella Salmonella species are predominantly motile enterobacteria found in the digestive tracts of humans and animals especially reptiles. Food and water can also be contaminated with the bacteria if … Read more
Plant movements do exist. Plant use movements as an adaptation to escape or minimize injury from harmful external factors or move towards scarce resource or otherwise secure food. For example, the primary root moves downward where it can obtain water and mineral nutrients from deep down while the shoot moves upward to be exposed to … Read more
What Is Recursion? Recursion is a method of solving a problem where the solution depends on solutions to smaller instances of the same problem. The approach can be applied to many types of problems. Recursion is used in variety of disciplines ranging from linguistics to logic. The most common application of recursion is in mathematics … Read more
Sols can be defined as colloidal systems with solid as dispersed phase and liquid as dispersion medium. Lyophobic sol and Lyophilic sol are the only types of sols. Lyophilic sols commonly described as liquid loving sols have a greater affinity for solvent. These sols are prepared easily by shaking or warming the dispersion phase in … Read more
A Proportionate counter is an instrument for detecting and measuring the intensity of ionizing radiation. It is similar to a Greiger Mueller counter but operates at a lower potential difference such that the magnitude of the discharge is directly proportional to the number of gas molecules ionized by the detected particle. This may permit the … Read more
Gas solid chromatography and Gas liquid chromatography are both the main types of Gas chromatography. In both methods, either liquid or solid is used as a stationary phase whereas gas is used a mobile phase. Gas solid chromatography entails passage of a mixture of volatile compounds with differential migration through a column containing solid stationary … Read more
What Is logical Address? A logical address also referred to as a virtual address, is an address of something generated by the central processing unit (CPU) while a program is running. Usually, the operating system or some other programs uses base addresses as a measure to find addresses. In this case the base address refers … Read more
A covalent bond also referred to as a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electrons are pairs are referred to as shared pairs or bonding pairs and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent … Read more
What Are Loops? Looping in programming language is a feature which facilitates the execution of a set of instructions/functions repeatedly while some condition evaluates to be true. A program executes the sequence of statements many times until the stated condition becomes false. A loop consists of two parts, a body of a loop and a … Read more
