Nutrition :  Nutrition is the process of producing food/intake of nutrients and their further utilisation. * Food of an organisam is made of molecules like carbohydrates, fats and proteins. * Carbohydrates and fats provide energy and proteins are require for body building, repair and maintenance. * Enzymes are biological catalysts used to breakdown complex food substances into simpler ones which cells take up for their growth. 1) Macronutrients  : These nutrients mainly provide energy. E.g: carbohydrates, Fats and Proteins. 2) Micronutrients  : They do not provide energy, but their deficiencies can cause specific diseases and abnormalities. E.g: vitamens and Minerals. Autotrophic   Nutrition : It is the process by which organisms can synthesise organic food materials from inorganic raw materials. * It is the process by which autotrophs take in raw materials from the environment and convert them into stored f...

Coronaviruses   are a group of viruses that causes diseas in mammales and birds. In humans, corona viruses cause respiratory tract infections that are typically mild, such as some vauses the common cold ( among other possible causes, predominantly rihnoviruses), through rarer forms can be lethal, such as SARS, MERS, and COVID-19. Sympotems vary in other species: in chickens, they cause upper respiratory tract disease, while in cows and pigs they cause diarrhea. Disovery of coronavirus  :    Human coronaviruses, first characterized in the 1960s, are responsible for a substantial proportion of upper respiratory tract infections in children. Since 2003, at least 5 new human coronaviruses have been identified, including the  severe acute respiratory syndrome   coronavirus , which caused significant morbidity and mortality.  NL63 , representing a group of newly identified group I coronaviruses that includes  NL  and the...
