Classification of matter • All the objects and substances that we see in the world are made of matter. • This matter can be classified according to whether it is a mixture or a pure substance. • A mixture is a combination of two or more substances‚ where these substances are not bonded (or joined) to each other and no chemical reaction occurs between the substances. Examples of mixtures are air (a mixture of different gases) and cereal in milk. • The main characteristics

holds the soil particles together. When the leaves from the plant of the Giant Miscanthus falls onto the ground it is decomposed into humus. Organic matter releases many plant nutrients as it decomposed into the soil‚ including nitrogen (N) and Phosphorus (P). This concept of organic matter benefits and holds a great impact on Giant Miscanthus. Therefore‚ the practices of crop management contribute to

Vitamins and Minerals Vitamins and minerals are essential nutrients that every cell needs. Vitamins can function like hormones or as antioxidants. Minerals are essential to important bodily functions such as producing energy‚ growing‚ and healing. Minerals are required for fluid balance‚ development‚ nervous system maintenance .Minerals and vitamins‚ function as coenzymes and participate in enzymatic reactions in the body. Vitamin and mineral deficiencies can affect the brain many different ways

A Comparison of the Effects of Three GM Corn Varieties on Mammalian Health Bs Biology 1-1 Dr. Arsenio Abstract We present for the first time a comparative analysis of blood and organ system data from trials with rats fed three main commercialized genetically modified (GM) maize (NK 603‚ MON 810‚ MON 863)‚ which are present in food and feed in the world. NK 603 has been modified to be tolerant to the broad spectrum herbicide Roundup and thus contains residues of this formulation. MON 810 and

need our help. As a result of the pollution Lake Erie contained high levels of phosphorus and nitrogen. Since Lake Erie has such high levels of phosphorus and nitrogen it’s known as the “dead sea”. Factories cause some of the pollution; most of the pollution is caused from fertilizer on fields‚ agricultural runoff‚ and city sewer plants. “As a result of these pollutants‚ Lake Erie contained increased levels of phosphorus and nitrogen‚ which contributed to eutrophication a process that encourages the
