Naseer Awan Genetic Engineering should not be encouraged The population of the world is rapidly increasing every year and it is predicted that it will be doubled in the next fifty years. Ensuring an adequate food supply for this growing population is going to be a major challenge for the world in the coming years. Genetic engineers claim that genetically modified foods have numerous characteristics which can meet this global demand. Although genetic engineering technology in agriculture can

Class X Question 1: Chapter 1 – Chemical Reactions and Equations Science Why should a magnesium ribbon be cleaned before burning in air? Answer Magnesium is very reactive metal. When stored it reacts with oxygen to form a layer magnesium oxide on its surface. This layer of magnesium oxide is quite stable and prevents further reaction of magnesium with oxygen. The magnesium ribbon is cleaned by sand paper to remove this layer so that the underlying metal can be exposed into air. Question

Introduction: A chemical reaction involves the breaking and forming of bonds in order to create the necessary energy required to cause movement. Each reaction is catalyzed (an increase in rate because of a present catalyst) by a specific enzyme. Enzymes are able to denature proteins‚ meaning that a protein loses its original shape by uncoiling‚ giving it a random‚ unstructured shape. The pineapple plant contains bromelain which‚ because of its unique characteristics‚ keeps gelatin from thickening

STATEMENT OF PURPOSE FOR AUTOMOTIVE ENGINEERING What can’t be achieved by the person who is determined? This has been the motto of my life since my childhood. I do believe that if one sets one’s goal high and tends to endeavor inflexible then one’s feet will definitely carry to one’s destination no matter what. It is this belief that has propelled me throughout my academic career in all my accomplishments till today and fuels my passion to study further. My strong and determined will and fervor is
