Biological Molecules Introduction: Without carbon‚ nitrogen‚ hydrogen‚ sulfur‚ oxygen and phosphorus‚ life wouldn’t exist. These are the most abundant elements in living organisms. These elements are held together by covalent bonds‚ ionic bonds‚ hydrogen bonds‚ and disulfide bonds. Covalent bonds are especially strong‚ thus‚ are present in monomers‚ the building blocks of life. These monomers combine to make polymers‚ which is a long chain of monomers strung together. Biological molecules can be

Trees alter the environment in which we live by moderating climate‚ improving air quality‚ conserving water‚ and harboring wildlife. Climate control is obtained by moderating the effects of sun‚ wind‚ and rain. Radiant energy from the sun is absorbed or deflected by leaves on deciduous trees in the summer and is only filtered by branches of deciduous trees in winter. We are cooler when we stand in the shade of trees and are not exposed to direct sunlight. In winter‚ we value the sun’s radiant energy

Analysis: The graph of oxygen uptake vs time taken to run 1.5 miles has a negative linear association. As oxygen uptake increases‚ the time taken to run 1.5 miles decreases. This is can be seen through the gradient which has a value of 0.1705. This means that as the oxygen uptake increases by 1 ml/kg the amount of time taken to run 1.5 miles tends to decrease by approximately 1.7 minutes. The graph has a moderate relationship because the data is scattered in a wide band along the line of best fit

out of carbon. According to Encyclopedia: "The use of special manufacturing techniques results in highly porous charcoals that have surface areas of 300 - 2‚000 square meters per gram. Charcoals are widely used to adsorb odorous or colored substances from gases or liquids." The problem with charcoals is that its production efficiencies are generally low‚ with as much as 60-80% of energy in the wood lost. Adding to this loss is the poor efficiency of many charcoal stoves‚ some as low as 3%. (http://www

Lung cancer is the most commonly diagnosed cancer in the world‚ according to the World Health Organisation. In the UK‚ it ’s the second most-frequently occurring cancer among men (after prostate cancer)‚ accounting for 1 in 7 new cases‚ and the third most-frequently diagnosed cancer in women (after breast and bowel cancer) accounting for about 1 in 9 new cases. However‚ numbers have dropped considerably in recent times‚ by about 16% in the last decade alone. Dr Patrisha Macnair last medically reviewed
