element that burns in nitrogen. It is marvellous in fireworks. Phosphorous is an essential component of living systems and is found in nervous tissue‚ bones and cell protoplasm. Magnesium is an important element for plant and animal life. Chlorophylls are porphyrins based upon magnesium. The adult human daily requirement of magnesium is about 0.3 g

cycle processes are: * Photosynthesis Plants undergo photosynthesis that helps them produce energy and food for themselves. During photosynthesis‚ plants take in carbon dioxide (CO2) and absorb water (H2O) with the help of their roots. The chlorophyll present in the leaves and the energy from the sun‚ helps convert CO2 and H2O into O2‚ sugar and water vapor. Oxygen (O2) is released by the plants as bi-product into the atmosphere. * Respiration Just as plants carry out photosynthesis‚ animals

The Use of Sweeteners and the Rise in Obesity I have selected to discuss the relationship of the sweetener sugar (sucrose) between its consumption and the rise in obesity. There is a problem with the increase in sugar consumption. Sugar both drives fat storage and makes the brain think it is hungry‚ setting up a “vicious cycle‚” according Robert Lustig‚ MD‚ a UCSF pediatric neuroendocrinologist. Obesity is one of the top underlying preventable causes of death in the U.S. The rise of obesity

Biology Major substances: Organic compounds – are compounds that contain carbon and were originally made by living things e.g. carbohydrates‚ lipids‚ proteins‚ nucleic acids Inorganic compounds – are compounds do not contain carbon as a main element Organic compounds | Composition | Function | Proteins | Carbon‚ hydrogen‚ oxygen and nitrogen | Used in the structure‚ storage‚ movement and transport of cells for growth and repair. | Lipids | Carbon‚ hydrogen and oxygen | Stores energy

thus chemical energy is the product. This is different from respiration because respiration transforms chemical energy into energy usable by cells; in this case chemical energy is the source. Photosynthesis occurs in the chloroplasts‚ using the chlorophyll inside of the chloroplasts‚ while respiration occurs in the mitochondria. Photosynthesis produces oxygen as a by-product‚ while aerobic respiration requires oxygen to even work. Photosynthesis produces NADPH2 in its workings‚ while aerobic respiration

energy from sunlight to produce sugar‚ which cellular respiration converts into ATP‚ the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy‚ is associated with the actions of the green pigment chlorophyll. Most of the time‚ the photosynthetic process uses water and releases the oxygen. Cellular respiration allows organisms to use (release) in the chemical bonds of glucose(C6H12O6). The energy in glucose is used to produce ATP. Cells use

ALGAE Algae are eukaryotic organisms that have no roots‚ stems‚ or leaves but do have chlorophyll and other pigments for carrying outphotosynthesis. Algae can be multicellular or unicellular. Unicellular algae occur most frequently in water‚ especially in plankton.
