Acids, Bases and Salts.

Acid An acid is a substance which forms H+ ions as the only positive ion in aqueous solution. Examples:- Hydrochloric acid dissolved in water forms H+ and Cl– ions HCl —> H+ + Cl–   Sulphuric acid dissolved in water forms H+ and SO42- ions H2SO4 —>2H+ + SO42-   Nitric acid forms H+ and NO3– ions when dissolved in water HNO3 —> H+ + NO3–   … Read more

Biotechnology

Biotechnology is defined as the industrial application of living organisms and their biological processes such as biochemistry, Microbiology, and Genetic engineering, in order to make best use of the Microorganisms for the benefit of mankind. Modern biotechnology provides breakthrough products and technologies to combat debilitating and rare diseases, reduce our environmental footprint, feed the hungry, … Read more

Tissue Culture

 Tissue culture Tissue culture, a method of biological research in which fragments of tissue from an animal or plant are transferred to an artificial Environment in which they can continue to survive and function. The cultured tissue may consist of a single cell, a Population of cells, or a whole or part of … Read more

Stem Cell Research

 Stem Cell Research Stem cells are undifferentiated, or “blank,” cells. This means they’re capable of developing into cells that serve numerous functions in different parts of the body. Most cells in the body are differentiated cells. These cells can only serve a specific purpose in a particular organ. For example, red blood cells … Read more

Methods of preparing magnets, molecular theory of magnetism, demagnetization

Methods Of Preparing Magnets Some magnets can be created using any of the following ways below. Induction Stroking Using electricity Since these magnets can be made, they are usually referred to as temporary magnets. Electromagnets are magnets made using electricity and so are called temporary magnet since they only show their magnetic influence when there … Read more

Microbiology

 Microbiology Microbiology is the study of microbes or the living organisms that are too small to be visible with the naked eye. These living things can be seen only with the use of a Microscope. These life forms are called Microorganisms or microbes. Microorganisms include bacteria, archaea, viruses, protozoa, microscopic Fungi and yeasts, … Read more

Molecules

 Molecules Molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance. The division of a sample of a substance into progressively smaller parts produces no change in either its composition or its chemical properties … Read more

Molecular Breeding And Marker Assisted Selection

 Molecular breeding and marker assisted selection Molecular breeding Molecular Breeding or Marker assisted breeding (MAB) is the process of using the results of DNA tests to assist in the selection of individuals to become the parents in the next generation of a genetic improvement program. The choice among various methods of MAB depends … Read more

Introduction And Application Of Genetic Engineering

 Introduction and application of Genetic engineering Genetic engineering Genetic engineering, the artificial manipulation, modification, and recombination of DNA or other nucleic acid Molecules in order to modify an organism or Population of organisms. The term genetic engineering initially referred to various techniques used for the modification or manipulation of organisms through the processes … Read more

Principal of inheritance and variation

Principal of inheritance and variation Inheritance or Heredity is the genetic information passing for traits from parents to their offspring, either through asexual Reproduction or sexual reproduction. This is the process by which an offspring cell or organism acquires or becomes predisposed to the characteristics of its parent cell or organism. Through heredity, variations exhibited … Read more
