Carbon Footprint The term “carbon footprint” refers to the amount of carbon dioxide we emit into the air every year. C02 is produced by many sources and is the gas responsible for Global warming and alarming changes in our climate. As we use our resources‚ the negative impact on our environment increases. The more C02 emitted in the air the more our ozone layer is affected. C02 is a natural gas and is always being emitted and absorbed to and from the air. There is a certain amount of carbon

DNA Structure Monday‚ 15 April 2013 9:01 AM - DNA = Deoxyribonucleic acid DNA is a double-helix: it has two strands that twist around each other Each strand is made of single units call nucleotides It has a sugar-phosphate backbone Bases join the two strands by hydrogen bonds ○ These bases are cytosine‚ guanine‚ adenine and thymine. - Complementary base pairing is a key idea in genetics: C pairs with G‚ and T pairs with A. - Each strand of DNA can be millions of base pairs in length and is

Abstract: This project looks at how the temperature of an experiment can affect its reaction time. The purpose of this experiment is to determine if dissolving reactions are affected by waters temperature. I believe that if the H2O temperature increases‚ then the Alka-Seltzer tablet will dissolve faster because the hot water molecules will move faster colliding with the tablet particles. Water will be the independent variable due to the fact is will always stay in its same form throughout the

Dissolution Rates of Paracetamol in Different Temperatures Rowan Boreham and Cameron Matheson Introduction Panadol Rapid Soluble‚ is paracetamol based a medical drug that treats pain and discomfort associated with headache/tension headache‚ migraine‚ toothache‚ muscular aches‚ cold and flu symptoms‚ sore throat and menstrual pain (Medsafe‚ 2012). While there are other recognised sources of pain relief‚ Panadol has been widely recognized as a being of a high standard treatment for pain. There for

Hypothesis The optimum temperatures of Alcalase and Savinase will be different. Above and below their optimum temperatures activity will decrease. Biological explanation This investigation is designed to look at the effect of temperature on the activity of the proteases Alcalase and Savinase. By the end of it I hope to know the optimum temperature of both proteases. The substrate I am going to use during the experiments is the protein gelatin‚ which is a translucent‚ colourless‚ brittle solid

When (if ever) should we trust our senses to give us truth? If there is an answer to this question the logical process would be to analyse the critical parts and define key area’s within the argument; and then begin the process to create a logically structured argument that can act as our response or answer (but to what level of certainty?). Our senses are based on our perception‚ our ability to use our combined senses to understand and interact with our environment. Using information from our

gradual increase in temperature that is from 15 Celsius to 22 Celsius of the Earth’s surface that has worsened since the industrial revolution Over the past two decades the effect has become more marked. Considerable evidence exists that most of this warming has been caused by human activities... that’s to say we have altered the chemical composition of the atmosphere through a buildup of greenhouse gases – primarily carbon dioxide‚ methane‚ and nitrous oxide. this is what the carbon footprints calls

The Respiratory Rate of Goldfish Affected in Lower Water Temperature Introduction: Temperature is a key influence that can change the respiratory rate of an ectothermic animal: Carassius auratus (commonly known as a goldfish). The respiration of a goldfish will change depending on certain factors. First‚ goldfish are exothermic‚ as are all fish. Their body temperature is determined largely by the temperature of the surrounding water. They absorb energy from the water (and to a far lesser extent
