What Is Tension? Tension is described as the pulling force transmitted axially by the means of a string, a cable, chain or similar one-dimensional continuous object or by each end of a rod, truss member or similar three-dimensional object; tension might also be described as action-reaction pair of forces acting at each end of said … Read more
In digital logic and computing, a counter is a device which stores and sometimes displays the number of times a particular event or process has occurred, often in relation to a clock. The most common type is a sequential digital logic circuit with an input line referred to as the clock and multiple output lines. … Read more
What Are Biodegradable Substances/Waste? Biodegradable substance is a form of substance originating naturally from plant or animal sources, which may be broken down into carbon dioxide, water, methane or simple organic molecules by action of bacteria, fungi and other living organisms by composting, aerobic digestion, anaerobic digestion or similar processes. Biodegradable substances upon braking up … Read more
Most multi-cellular organisms require a mechanism for transporting nutrients throughout their bodies and for removal of waste products. The circulatory system has evolved over time from simple diffusion through cells, in the early evolution of animals, to a complex network of blood vessels that reach all parts of the human body. This extensive network supplies … Read more
Many animals, including humans have two types of chromosomes: Autosomes and sex chromosomes. Sex chromosomes are those that are needed for determining sex (male or female) of an individual. Autosomes are all the rest of the chromosomes that are not needed for sex determination. What Is Autosome? Autosomes are chromosomes that do not carry any … Read more
Disinfection and disinfection are the two common types of decontamination. Decontamination is the process of decreasing antimicrobial presence in an area or on a surface. Sterilization is the process of removing all harmful microorganisms from objects and surfaces whereas disinfection means to eliminate most harmful microorganisms, but this doesn’t include spores. Both procedures (disinfection and … Read more
The structures that enable the formation of spindle fibers are known as centrioles and the organelle that organizes their formation is referred to as centrosome. During mitosis, centrosomes are replicated by duplicating each Centriole. The four centrioles then divide into two centrosomes, each with one Centriole at a right angle to the second Centriole. What … Read more
Homozygous Homozygous describes the genetic condition or the genetic state where an individual has inherited the same DNA sequence for a particular gene from both their biological mother and their biological father. Homozygous allele may be dominant or recessive. An allele is a version of a gene that affects the functionality of the protein produced … Read more
DNA replication is the biological process by which genetic information is duplicated to produce two identical copies of an organism’s genome. DNA replication occurs in all living organisms acting as the basis for biological inheritance. The cell possesses the distinctive property of division which makes replication of DNA essential. DNA is made up of a … Read more
What Is Growth? Growth is the increase in the cell size and number that take place during the life history of an organism. The increase in size and changes in shape of a developing organism depend on the increase in the number and size of cells that make up the individual. Increase in size resulting … Read more
