Amwoga Khalwale Voltage Amplifier A voltage amplifier is an amplifier that amplifies given voltage for a larger voltage output. It is characterized by a high input impedance and low output impedance. This is useful for reading and adapting small signals such as boosting an audio signal before sending it on its way to speakers. The voltage amplifier … Read more
What Is Epigeal? Epigeal germination is a type of germination whereby the seed leaves or the cotyledons are brought on to the surface or above the soil along with the shoot during germination. This is usually due to rapid elongation and curved-like shape of the hypocotyl. This change in the shape or curvature of the … Read more
Virtual Circuits Virtual circuit (VC) is a means of transporting data over a packet switched computer network in such a way that it appears as though there is a dedicated physical layer link between the source and destination end systems of this data. Before the data transfer begins, the source and destination identify a suitable … Read more
Enzymes Enzymes are biological molecules typically proteins that speed significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve as a wide range of important functions in the body, such as aiding in digestion and metabolism. Some enzymes help break large … Read more
Joint Photographic Experts Group (JPEG) JPEG is an acronym for ‘’ Joint Photographic Experts Group”. It’s a standard image format for containing lossy and compressed image data. Despite the huge reduction in file size JPEG images maintain reasonable image quality. This unique compression feature allows JPEG files to be used widely on the internet, computers … Read more
What Is SN1 Reaction? The SN1 reaction is a substitution reaction in organic chemistry. ‘’SN’’ stand for ‘’nucleophilic substitution’’ and ‘’1’’ says that the rate-determining step is unimolecular. Thus, the rate equation is often shown as having first-order dependence on electrophile and zero-order dependence on nucleophile. This relationship holds for situations where the amount of … Read more
DNA is a two-stranded molecule. One strand of DNA holds the information that codes for various genes, this often referred to as the template strand or antisense strand (containing anticodons). The other complementary strand is referred to as the coding strand or sense strand (containing codons). What Is Template Strand? Transcription is the process in … Read more
Buffalo A buffalo is a large, bovine mammal found in Africa and Asia. It is usually black or dull black in color. A buffalo is a very robust species. There are two primary species of buffalo: the Water or Asian buffalo (Bubalus bubalis) and the African buffalo (Syncerus caffer). Much like the American bison, the … Read more
Orthographic projection can be described as a method of representing three-dimensional objects, usually by three two-dimensional drawings in each of which the object is viewed along parallel lines that are perpendicular to the plane of the drawing. Oblique projection is a simple type of technical drawing of graphical projection used for producing two-dimensional images of … Read more
What Is Diffusion? Diffusion is a physical process that refers to spontaneous movement of particles from a region of high concentration to a region of low concentration. Concentration refers to how much a particular object or particle is in a given space. Gasses and molecules in a liquid have a tendency to diffuse from a … Read more
