What Is Grafting? Grafting is the technique of connecting two pieces of living plant tissue together in such a way that they will unite and subsequently grow and develop as one composite plant. In grafting, two plant sections, the stock and scion are very crucial. Stock/rootstock is the rooted plant upon which a branch of … Read more
Zygotic Meiosis Zygotic meiosis is meiosis of a zygote immediately after karyogamy which is the fusion of two cell nuclei. This way, the organism ends its diploid phase and produces several haploid cells. These cells divide mitotically to form either larger, multicellular individuals or more haploid cells. Zygotic meiosis takes place in some lower plants … Read more
Inflorescence can be broadly classified based on the following: Number and position of flowers Sequence of flower development The nature of inflorescence branching However, the common classifications of inflorescence are Racemose and cymose. Others include: Cyathium Verticillaster Hypanthium What Is Racemose Inflorescence? Racemose is a type of inflorescence in which the main axis of flower … Read more
Allowance Allowance is a concept very similar to tolerance but is different in the sense that allowance refers to tolerance in dimension that is deliberately given to a metal during the process of manufacture and design. This is a planned deviation from the standard that is intended to allow for compensation should there be any … Read more
What Is Silicon Controlled Rectifier (SCR)? A silicon Controlled Rectifier is a 3 terminal and 4 layer semiconductor current controlling device. It is mainly used in the devices for the control of high power. Silicon Controlled Rectifier is also referred to as SCR diode, 4-layer diode, 4-layer device or Thyristor. It is made up of … Read more
Paramagnetism Paramagnetism is a form of magnetism whereby some materials are weakly attracted by an externally applied magnetic field and form internal induced magnetic fields in the direction of the applied magnetic field. Materials or substances that display Paramagnetism are referred to as paramagnetic. Some compounds and most chemical elements are paramagnetic under certain circumstances. … Read more
In the motors or generators, both the parts like rotor and stator play a key role. The main disparity between them is that the stator is an inactive part of the motor whereas the rotor is the rotator part. What Is A Stator? The stator is the stationary component of electromagnetic circuits. In different configurations, … Read more
What Is Uninterruptible Power Supply (UPS)? An Uninterruptible Power Supply (UPS) is a component that allows an electronic device to keep running for at least a short time when the primary power source is lost. UPS devices also provide protection from power surges. A UPS contains a battery that ‘’kicks in’’ when the device senses … Read more
Wind occurs because of horizontal and vertical differences (gradients) in atmospheric pressure. Accordingly, the distribution of winds is closely related to that of pressure. Near the Earth’s surface, winds generally flow around regions of relatively low and high pressure –cyclones and anticyclones respectively. Cyclones A cyclone is a large scale air mass that rotates around … Read more
What Is Aldehyde? Aldehyde can be described as any group of organic compounds in which a carbon atom shares a double bond with an oxygen atom, a single bond with a hydrogen atom and a single bond with another atom or group of atoms (designated R in general chemical formulas and structure diagrams). The carbon … Read more
