Living things get energy to do things through photosynthesis‚ food molecule breakdown‚ build up‚ storage‚ and lastly cellular respiration. All of these ideas are the reason that myself and others have energy to do anything and everything. Photosynthesis is one way plants(plants are the main source of energy for all things)get energy to do things. The reactants of this are water‚ carbon dioxide‚ and although light energy is not a reactant‚ it is necessary once the energy from the seed is gone. Carbon

others will separate. Introduction Food is a vital source of energy that is needed for survival‚ without this energy source our bodies wouldn’t be able to function. All food can be broken down into various food groups such as water‚ proteins‚ carbohydrates‚ vitamins‚ fats‚ fibre and minerals. Our bodies need all of these food groups to function with each of them playing a specific role. These food groups are present in our every day food and are taken into our body through a process of digestion

MACROMOLECULS LAB: What are the mystery powders? Period: 4 Asia Enoch Introduction: A carbohydrate is an immediate form of energy in your body. Monomers is smaller than a polymer. For carbohydrate the monomer is sugar and the polymer is a polysaccharides. Carbohydrates are important to our body because we need to use energy. The purpose of this lab is to figure which one is the monomer and which one is the polymer. Hypothesis: If I place two drops of iodine into the mystery powder‚ it

Food labeling has come a long way. It’s surprising but it wasn’t until 1990 that the Nutrition Labeling and Education Act required all packaged foods to include nutritional information. Required categories of nutritional labeling regulations include the ingredients list‚ serving size‚ nutrition facts‚ and daily value standards of nutrients. Additionally‚ if the product wishes to make claims about nutrients and healthfulness‚ they must substantiate them in some way. Nutritional information for non-packaged
