Amwoga KhalwaleWhat Are Stack Data Structure? Stack is an abstract data type that serves as a collection of elements, with two principal operations: PUSH, which adds an element to the collection and POP which removes the most recently added element that was not yet removed. Generally, stacks are based on Last In First Out (LIFO) principle … Read more
Reflection Of Light Light rays change direction when they reflect off a surface, move from one transparent medium into another or travel through a medium whose composition is continuously changing. Reflection of light is the bouncing back of light when it strikes a smooth surface. If the surface is smooth and shiny like glass, water … Read more

What Is A Rheometer? A Rheometer is a laboratory instrument used to measure the way in which a liquid, suspension or slurry flows in response to applied forces. It is used for those fluids which cannot be defined by a single value of viscosity and therefore require more parameters to be set and measured. Types … Read more
A carbohydrate is an organic compound consisting of carbon, hydrogen and oxygen. Carbohydrates are classified into monosaccharides, disaccharides, oligosaccharides and polysaccharides. The monosaccharides are the simplest forms of carbohydrates and are further classified based on the carbonyl group they contain. Accordingly, monosaccharides are the simplest form of carbohydrates and may be subcategorized as Aldoses or … Read more

These plaintext units may be individual letters or characters, letter … Read more
What Is Primary Growth? All plant growth occurs by cell division elongation. Cell division occurs primarily in regions of undifferentiated cells known as meristems. Cell division in the apical meristems and subsequent elongation and maturation of the new cell produces primary growth. Therefore, primary growth can be defined as is growth that occurs as a … Read more
What Is Transpiration? Transpiration is the process by which plants lose water in the form of vapor to the atmosphere through the stomata. Transpiration cools the plant, changes osmotic pressure of cells and enables mass flow of mineral nutrients and water from roots to shoots. Two major factors influence the rate of water flow from … Read more
Periodic Signal A signal is considered to be periodic signal if it completes a pattern within a measurable time frame, called a period and repeats that pattern over identical subsequent periods. A period is defined as the amount of time (expressed in seconds) required to complete one full cycle. Sinusoidal wave, cosine wave, triangle wave … Read more
