1. Define ecology. Identify the two features of organisms studied by ecologists. Ecology is the scientific study of the interactions between organisms and the environment‚ which in turn determine both the distribution of organisms and their abundance. Ecologists study how interactions between organisms and the environment affect phenomena such as the number of species living in a particular area‚ cycling of nutrients in a habitat‚ and the growth of populations. 2.

MATHEMATICAL MODELLING OF MICROWAVE HEATING OF FOOD By M . SHIVA KUMAR ( 04AG1008 ) Under the guidance of PROF. SURESH PRASAD ABSTRACT • The use of microwaves in the food industry is attributed to the lower time needed to increase the temperature of foodstuffs compared to the traditional heating methods. •However‚ the heating is not uniform and the products show hot and cold spots. • In order to analyze the behaviour of foods heated by microwave oven‚ a mathematical method was developed

Effects of Microwave Apparatus on Food and Humans Hikaru Sugimori A microwave is a kitchen appliance that cooks food by dielectric heating. This is done by using radiation to heat water and other polarized molecules within the food. Using the microwave‚ people can buy pre-cooked foods at convenient stores and cook them in the microwave at home in a matter of minutes. Microwave ovens became widespread in the 1970s and 80s‚ and today‚ 90% of American households have a microwave. Microwaves are a very

MYP Science One World Essay : Microwave Oven Word Count : 1‚325 Imagine what life was like before the microwave oven was created. Time would be wasted in reheating certain foods when using a stove to reheat. As it takes a long time to preheat a stove‚ which is what was used before the microwave oven to reheat food. Using a traditional stove also tends to create a more stressful environment when being used because of the heat that builds up in the area making it uncomfortable. This does not exist
