What Is An Ideal Gas? An ideal gas is a hypothetical gas whose molecules exhibit no intermolecular attractive forces and undergo elastic collision with each other and with the walls of the container. An ideal gas conforms to a particular idealized relation between pressure, volume and temperature referred to as ideal gas law. The ideal … Read more
What Is Single Circulation? Single circulation is a circulation in which blood flows once through the heart in one complete cycle of the body with the blood being pumped through the capillaries of the gills and on to the capillaries of the body tissues. In an open circulatory system, blood vessels transport all fluids into … Read more

What Is Pairwise Sequence Alignment? Pairwise alignment is one of the most fundamental tools of bioinformatics and underpins a variety of other, more sophisticated methods of annotation. The goal of Pairwise sequence alignment is to establish a correspondence between the elements in a pair of sequence that share a common property, such as common ancestry … Read more
A feeding tube is a medical device used to provide nutrition to people who cannot obtain nutrition by mouth, are unable to swallow safely, or need nutritional supplementation. The state of being fed by a feeding tube is called gavage, enteral feeding or tube feeding. Placement may be temporary for the treatment of acute conditions or lifelong in the case of … Read more
Precipitation Titration Titration is a process by which the concentration of an unknown substance in solution is determined by adding measured amounts of a standard solution that reacts with the unknown. Then the concentration of the unknown can be calculated using the stoichiometry of the reaction and the number of moles of standard solution needed … Read more
Hemolysis is the breakdown of red blood cells. Hemolysis is used in the empirical identification of microorganisms based on the ability of bacterial colonies grown on agar plates to break down red blood cells in the culture. When the organism has been grown on blood agar plates, it can be classified with regard to whether or not it has caused hemolysis in the red blood cells (RBCs) incorporated in … Read more
What Are Ferrous Metals? A metal with the descriptor ‘’ferrous’’ means that it has iron in its composition. When the term ferrous metal is used, it also usually implies that iron is a large percentage of the elemental composition. While it is difficult to place the properties of all ferrous metals under one umbrella, there … Read more
Formation of Compression And Rarefactions A longitudinal wave consists of successive compression and rarefaction that is formed due to continuous to and fro motion of a vibrating object. As an object vibrates back and forth, it pushes on neighboring air particles. The forward motion pushes air molecules horizontally to the right and the backward retraction … Read more
Clinical Thermometer A clinical thermometer also referred to as medical thermometer is used for measuring human or animal body temperature. The thermometer consists of a cylindrical bulb which is filled with mercury. A capillary tube of uniform and a fine bore is attached to the bulb.
