Understanding the key concepts of general chemistry is both necessary and beneficial for a broad spectrum of science‚ engineering and healthcare majors. However‚ without some hands-on laboratory experience‚ this understanding is likely to be incomplete

Chemistry plays an important part in studying Biology. It answers some questions that Biology could not explain alone. Questions like: How does an organism convert foods for energy? How do plants use sunlight and water into all the things that cells needed to grow and reproduce? How does the basic unit of life passed through generation to the next? Here are some contributions of Chemistry in Biology: • Within atomic theory‚ chemistry contributes towards biology in the understanding of atoms and elements

was 1.89 per cent and 0.68 per cent‚ respectively. Productivity gains have plateaued raising concerns about food security. All this goes to show that the country now urgently needs a follow up green revolution to the one of the 1960s which led to major breakthroughs in wheat and rice production. The next green revolution has to happen to chase the twin goals of food security and nutritional diet. Without the second revolution‚ which can be postponed at the nation’s peril‚ the supply side’s response

Salt from green beans Name: Ashni Couprie and Dennise Susanto Class: 5c Introduction From previous experiments we ’ve learned that salt is extracted from green beans. To be more specific: salt is extracted from when the beans are cooked in water in which salt has been dissolved. This experiment is based upon the osmoses theory. According to this theory the cell walls of the green beans are what we call a semi permeable membrane. This membrane only lets water through and not the substance

Design Experiment: Enzyme Inhibitors. Research question: What is the effect of adding lead nitrate solution on the activity of amylase enzyme? Aim: To test the effect of adding nitrate solution on the activity of amylase. Background Information: Inhibitors are molecules which repress or prevent another molecule from engaging in a reaction. They are substances that attach themselves onto an enzyme and reduce or prevent the enzyme’s ability to catalyse reactions. Competitive Inhibitors are inhibitors

# 49 Diet The food an animal eat everyday is called diet. Most animals need 7 types of nutrients in their diet: carbohydrates‚ proteins‚ fats + water‚ fibre‚ vitamins‚ minerals. The amount of energy needed is provided mainly by our carbohydrate and fat intake. Your dietary requirements depend on your age‚ sex and activity. - Age: The energy demand increases until we stop growing. While children are growing they need more protein per kilogram of body weight than adults do. - Sex: Generally

Dry Wallum The dry wallum is a harsh environment that is battered by the sun and wind every day and with a base of porous sand; water availability is very scarce and must be conserved. The abiotic factors in the dry wallum are that the area is exposed to high amounts of sunlight which causes a loss of water in the leaves through transpiration. Since the wallum is so dry and hot; bush fires play a major cycle in the dry wallum which the trees have adapted to cope with. The roots of the plant and
