Clostridium and other anaerobic bacteria dominate under anaerobic conditions at the bottom. Cellulose from the paper into glucose and that would be a trigger for the bacteria (Clostridium) to take in the glucose and partially break it down

2. At a party‚ Dickson was challenging his friends to see who could hold their breath and dive longest in the pool. Hoping to extend his time underwater‚ Dickson hyperventilates for several minutes before diving into the pool. Shortly after entering the water‚ he lost consciousness and nearly drowned. Explain what might have caused this. Hyperventilation is defined as breathing in excess of the metabolic needs of the body‚ eliminating more carbon dioxide that is produced‚ and consequently‚ resulting

was taken and this was repeated for 5 animals at 15oC and 25oC. The calculated average velocity of the animal was also collated with class results and recorded in a table RESULTS Length-specific O2 consumption rate was shown to be slightly higher in the warmer temperature of 25oC compared to the O2 consumption rate of artemia at 15oC (Figure 1). Contrastingly‚ the opposite applies for velocity‚ with the artemia in the colder environment of 15oC showing faster speeds of movement in comparison to

2 H2O2 → 2 H2O + O2 Although this reaction occurs spontaneously‚ enzymes increase the rate considerably. At least two different enzymes are known to catalyze this reaction: catalase‚ found in animals and protists‚ and peroxidase‚ found in plants. A great deal can be learned about enzymes by studying the rates of enzyme-catalyzed reactions. The rate of a chemical reaction may be studied in a number of ways including: • measuring the rate of appearance of a product (in this case‚ O2‚ which is given

Jonathan Swift was born on November 30‚ 1667 in Dublin‚ Ireland‚ the son of Protestant Anglo-Irish parents: his ancestors had been Royalists‚ and all his life he would be a High-Churchman. In 1673‚ at the age of six‚ Swift began his education at Kilkenny Grammar School‚ which was‚ at the time‚ the best in Ireland. Between 1682 and 1686 he attended‚ and graduated from‚ Trinity College in Dublin‚ though he was not‚ apparently‚ an exemplary student. In 1688 William of Orange invaded England‚ initiating
