Assignment 2 Option 1 1. Introduction Language represents human’s experiences and different fields hold different ways of language using. The language of science actively constructs scientific reality‚ i.e. a way of looking at the world‚ the roles assigned to readers and the way of organizing information (LING337-nominalisation). However‚ science may be presented diversely according to the different intended audience‚ purposes and modes. Three texts chosen in this paper are all concerned with the

be all that is needed in many cases. Artificial saliva or medicine to stimulate the salivary glands is sometimes used. What are the salivary glands? The salivary glands make spit (saliva). Saliva is important in the breaking down of the food that you eat. It makes food moist‚ lubricating it as it passes from the mouth to the gullet. It also contains enzymes in the saliva which break down some of the starch and fat in your food. [pic] There are three pairs of glands that make saliva. From

MULTICELLULAR ORGANISMS The complex multicellular animals and plants perform many different activities in order to exist. More energy is invested in all organisms for their accumulation and distribution of food‚ release of waste matters‚ movement‚ reproduction‚ and coordination of these activities. The different organisms have specialized tissues‚ organs and organ systems that work together for the good of the organisms. Thus the well-being of the whole organism depends on the integration

The ESOPHAGUS is the hollow muscular tube that leads from the mouth to the opening of the stomach. The STOMACH is a hollow muscle that contracts and relaxes to integrate digestive juices with the food causing it to breakdown

these parts help in the digestion of food. Digestions start from the mouth. Firstly‚ ingestion is the process of taking food via the mouth. When the food enters the mouth the food is then chewed‚ mixed with salivary gland‚ which produces and enzyme called salivary amylase. This enzyme breaks the food

Purpose: Cells produce toxic wastes‚ in this experiment hydrogen peroxide‚ and without some sort of molecule to break it down the cell will die‚ along with the organism itself. However with the aid of an enzyme‚ catalase‚ hydrogen peroxide is able to be broken down into an intermediate and thereafter harmless substances water and oxygen. The goal of this lab is to measure the reaction rate of this process in different substances such as a liver‚ a vegetable‚ and breast tissue. By using variables
