Fleming’s left and right hand rules were first discovered and described by John Ambrose Fleming in 19th century. These rules try to explain the relationship between magnetic field, the current and force. These rules only show the direction and do not determine the magnitude of magnetic field, current and force. In practice, Fleming’s Left Hand … Read more

What Is NPN Transistor? NPN is an acronym for Negative, Positive, Negative configuration. NPN transistor is a type of bipolar junction transistor which is composed of three layers, whereby two N-type doped semiconductor materials are separated by a thin layer of P-type doped semiconductor material. In NPN transistor, the majority charge carriers are electrons whereas … Read more

Among the many classifications of sugar, “reducing sugar” and “non-reducing sugar” stand out as two intriguing categories that often confuse both culinary enthusiasts and scientific minds alike. What Are Reducing Sugars? Reducing sugar is any carbohydrate which is capable of being oxidized and causes the reduction of other substances without having to be hydrolyzed first. … Read more

There are two types of transport pathway for the conduction of the water from one region to another. The path followed by the water can be Symplast or Apoplast pathway. The Symplast is the pathway in which the water molecules move through the plasmodesmata region in the cells. The Symplast is the living region present … Read more

Cytokinesis is the part of the cell division process during which the cytoplasm of a single eukaryotic cell divides into two daughter cells.  Cytokinesis can also be referred to as Cytoplasmic division or cell cleavage. In animal cells this is achieved by constriction of the plasma membrane, whereas in higher plants, it is accomplished through … Read more

What Are Homologous Structures/Organs? Many species have similar traits because they are descendants of a single common ancestor. These species developed from a single source and are related to a certain degree despite their current differences. The traits they share are referred to homologous structures. A homologous structure is an organ or body part that … Read more

What Is Stepper Motor? A stepper motor, also referred to as step motor or step ping motor, it is a brushless DC electric motor that divides a full rotation into a number of equal steps. Like all other motors, steppers also have a stator and a rotor, but unlike a normal DC motor the stator … Read more

What Is Caryopsis? The caryopsis is popularly known as a grain, is a specialized type of dry, one-seeded fruit (achene) characteristic of grasses, in which the ovary wall is united with the seed coat, making it difficult to separate the two except by specialized milling process. All the cereal grains except buckwheat have caryopses. What … Read more
