Chlorophyll clip_image002Outline the role of photosynthesis in transforming light energy to chemical energy (including raw materials needed for this process) Photosynthesis occurs in all green plants and is the beginning of nearly all food chains therefore a source of life to all living organisms. It is the process where plants transform light energy from the sun into chemical energy. By using light energy trapped by chlorophyll (light absorbing pigment)‚ plants combine carbon dioxide and

The Holy One of Israel‚ part 1 - - The Eternality of God “What is the toughest experience that you have ever been through?” A.W. Tozer “What comes to our minds when we think about God is the most important thing about us . . . I believe that there is scarcely an error in doctrine or a failure in applying Christian ethics to life that cannot be traced back finally to imperfect thoughts about God . . . If we would bring back spiritual power to our lives‚ we must begin to think of God more nearly

Acid Rain Air pollution is one of the most common outcomes of the combustion of fossil fuels. A common air pollutant that is released is sulphur dioxide and nitrogen oxides. This is because when coal and fuels obtained from crude oil are burned‚ sulpur and nitrogen is released into the atmosphere‚ which is eventually joint with the oxygen in the air to produce sulfur dioxide and nitrogen oxide. When these gases are emitted in sufficient quantities‚ it reacts with the water and oxygen in the atmosphere

Acid Rain Acid rain occurs when Sulphur Dioxide (SO2) is released into the atmosphere by electricity generation‚ motor vehicles‚ factories and by wildfires and volcanoes. Once released‚ the sulphur dioxide reacts with water to produce sulphuric acid. This has a pH of approximately 2-3 pH. This has a dramatic effect on water dwelling wildlife. Most water dwelling creatures can’t withstand water more acidic than pH 5. This causes the mass loss of life of animals such as trout‚ perch‚ frogs and mayflies

Executive Summary Part One: Paradigms And Principles Inside-Out Steven Covey studied over 200 years of writing about success. While studying these writings he began to recognize a distinct pattern surfacing. He found these writings attributed success to either Character Ethic or Personality Ethic. The majority of the literature of in the first 150 years focused on the philosophy referred to as Character Ethic. The foundations for success are based upon integrity‚ humility‚ fidelity‚
