What is genetic engineering ? Give an application of genetic engineering ? |
|
Answer» genetic engineering ?Genetic engineering, also called genetic modification or genetic manipulation, is the direct manipulation of an organism's genes using biotechnology. Give an application of genetic engineering ?In medicine, genetic engineering has been used to mass-produce insulin, human growth hormones, follistim (for TREATING infertility), human albumin, monoclonal antibodies, antihemophilic factors, vaccines, and MANY other drugs. In RESEARCH, organisms are genetically ENGINEERED to discover the functions of certain genes. |

Balance the above chemical equation |
|
Answer» a balanced chemical equation?Answer:- A chemical equation which has an equal NUMBER of atoms of each element in the reactants and products is called a balanced equation.Why is it necessary to balance a chemical equation?Answer:- The chemical equation must be balanced. If we do not balance the equation, it would be creating or losing atoms. This will be against the law of CONSERVATION of mass. According to law of conservation of mass, total mass of the reactants before the chemical reaction must be equal to the total mass of products after the chemical reaction. In other words, atoms can neither be CREATED nor be DESTROYED during the chemical reaction. Therefore, the number of atoms of each kind in the reactants must be equal to those in the products. |

Answer» 1. Brass2.The green coating is of copper hydroxide and copper carbonate. Brass is an "alloy" of copper and zinc metal in a certain proportion. ... This process is CALLED corrosion which is one of the types of oxidation reaction in which metal oxidized to hydroxide, oxides or carbonates.3.Tin4.nickel–iron alloy5.Aluminum and its alloyIt is used to prepare lining of milk cans and milk pails. This metal does not taint the milk, it is a soft metal. Durability is reduced because the metal is impure.6. Alloys commonly used for electrical soldering are 60/40 Sn-Pb, which melts at 188 °C (370 °F), and 63/37 Sn-Pb used principally in electrical/electronic work. This mixture is a eutectic alloy of these metals, which: has the lowest melting point (183 °C or 361 °F) of all the tin-lead alloys.7. The alloy is duralumin and its constituents are aluminium and copper with traces of manganese and magnesium.8.In addition to aluminium, the main materials in duralumin are copper, manganese and magnesium.9.it is a mixture of mercury and another metal, used especially to fill holes in teeth.gold and silver MINING since it amalgamates10.Gold is the most malleable and ductile of all known metals. A single ounce of gold can be beaten into a sheet measuring roughly 5 meters on a side. Thin sheets of gold, known as gold leaf, are primarily used in arts and crafts for gilding.11. 22-karat gold is 91.6% gold 12.Corrosion is a natural process that converts a refined metal into a more CHEMICALLY stable form such as oxide, hydroxide, or sulfide. There are several factors influencing the rate of corrosion including diffusion, temperature, conductivity, type of ions, pH value and electrochemical potential.Metal Type. One simple WAY to prevent corrosion is to use a corrosion resistant metal such as aluminum or stainless steel. ...Protective Coatings. The application of a paint coating is a cost-effective way of preventing corrosion. ...Environmental Measures. ...Sacrificial Coatings. ...Corrosion INHIBITORS. ...Design Modification.13.

What is genetic engineering ? Give an application of genetic engineering ? Don't google it! follow me |
|
Answer» tion:GENETIC engineering is the process of modifying an organism’s DNA to introduce NEW, desirable traits. Many organisms, from bacteria to plants and animals, have been genetically modified for academic, medical, agricultural, and industrial purposes. While genetic engineering has definite benefits, ethical concerns surround modifying humans and our food supply.Application of genetic engineering:An important application of recombinant DNA technology is to alter the genotype of crop plants to make them more productive, nutritious, rich in proteins, disease resistant, and less FERTILIZER consuming. Recombinant DNA technology and tissue culture techniques can produce high YIELDING cereals, pulses and vegetable crops.Some plants have been genetically programmed to YIELD high protein grains that could show resistance to heat, moisture and diseases.Genetic engineering plays significant role in the production of medicines.Microorganisms and plant based substances are now being manipulated to produce large amount of useful drugs, vaccines, enzymes and hormones at low costs. Genetic engineering is concerned with the study (inheritance pattern of diseases in man and collection of human genes that could provide a complete map for inheritance of healthy individuals. |
