Biocheminsider A molecular orbital is an orbital or wave function of a molecule’s electron. The function may be used to calculate the probability of finding an electron within a specified space or to predict the molecule’s chemical and physical properties. Robert Mulliken introduced the term “orbital” in 1932 to describe a one-electron orbital wave function. Electrons around a molecule can … Read more
A steak is a meat generally sliced across the muscle fibers, potentially including a bone. It is normally grilled, though can also be pan-fried. It is often grilled in an attempt to replicate the flavor of steak cooked over the glowing coals of an open fire. Steak can also be cooked in sauce, such as … Read more
A vulva is generally the name for the visible part of what most people just dub “vagina.” It encompasses all the external parts of the female nether regions including the mons pubis (fatty patch perched atop your pubic bone), the labia (inner and outer lips framing the vaginal opening), the clitoris and its protective hood, and more. … Read more
Overview Hybridization (also spelled hybridisation) refers to the process of producing offspring by mating two parents from different varieties or species. It is sometimes used synonymously with crossbreeding, which is defined as the process or the act of producing offspring particularly through mating two purebred individuals but come from different breeds or varieties, (sometimes, even species). … Read more
What are Transgenic Animals? Transgenic means that one or more DNA sequences from another species have been introduced by artificial means. Animals usually are made transgenic by having a small sequence of foreign DNA injected into a fertilized egg or developing embryo. Transgenic animals are animals which have been genetically transformed by splicing and inserting … Read more
The representatives of the phylum Platyhelminthes are commonly known as the flatworms or tapeworms. The word ‘Platyhelminthes’ is derived from the Greek word, ‘platy’ meaning flat and ‘helminth’ meaning worm. They are simple soft-bodied, bilaterian, unsegmented invertebrate animals. The Phylum Platyhelminthes makes up the 4th largest phylum among the animal kingdom. But among the acoelomate … Read more
What Is Iodine Test? The iodine test was first described by J.J Colin and H.F Gaultier de Claubry and independently by F. Stromeyer in 1884. The iodine test is used to test for the presence of starch in a given analyte. The test can be qualitative or quantitative. Objective Of Iodine Test To test for … Read more
What Is Tollens’ Test? Tollens’ test also referred to as silver-mirror test is a qualitative laboratory test used to distinguish between aldehyde and ketone. The test is named after a German chemist, Bernard Tollens who discovered the test. The test involves use of Tollens’ reagent which must be prepared immediately prior to its use as … Read more
What Is Fehling’s Test? The Fehling’s test was developed by German chemist Hermann von Fehling in 1849. It is generally a test for reducing sugars and non-reducing sugars; and also a supplementary to the Tollens’ reagent test. The test can also be used to differentiate between water-soluble carbohydrate and ketone functional groups. Objectives of Fehling’s Test To detect the presence of carbohydrates in a solution. To … Read more
