Carbon Essays

1. How are isotopes of an element different from one another? How are they the same? (10 points) The isotopes of an element have the same amount of protons, but a different amount of neutrons, so they vary in size. 2. Are mass number and atomic mass the same thing? …

In order to determine the effect of the substrate on the rate of respiration of yeast, Durham test tube method was used in the first experiment. In this method two test tubes was obtain, where test tube one contains distilled H20 with the 7 ml substrate glucose while test tube …

Today, the Earth is getting hotter for many different reasons. Nature or humans can cause this. Global warming is the cause of many natural problems such as forest fires or droughts. However, many people do not know what global warming is. Thus, what we have to do is attempt to …

Recently, “carbon footprint” has become as an extremely famous term that extensively use in the media, particularly, the United Kingdom (Wiedmann and Minx, 2008). This suggests that carbon footprint calculations are greatly needed as climate change is becoming more and more important to the political and collaborate agenda. However, the …

Introduction: Fermentation is a metabolic pathway that produce ATP molecules under anaerobic conditions (only undergoes glycolysis), NAD+ is used directly in glycolysis to form ATP molecules, which is not as efficient as cellular respiration because only 2ATP molecules are formed during the glycolysis. One type of fermentation is alcohol fermentation, …

The movie “An Inconvenient Truth” is not only a mere documentation it is a strong and very passionate message to the people all over the world that our planet is not on a slow progress to imminent doom, but that already all over the world we are experiencing the beginning …

For this experiment we studied an oxidation-reduction reaction of magnesium and hydrochloric acid solution. We compared the experimental measured amount of a product and the amount predicted by the theoretical calculation of a balanced equation: Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g) PROCEDURE First we obtained …

Glaciers are melting. The sea is rising. The highest CO2 levels in 650,000 years. The outlook is bleak. Climate Change, the most worrying environmental threat of our time is starting to unfold. Predictions of fiercer droughts, more severe cyclones, and more frequent floods invade our media and perhaps our consciousness. …

Among the most harmful and dangerous non-metal compunds are nitrogen oxides, sulphur dioxide, carbon dioxide, carbon monoxide, and hydrogen sulphide. These can cause devastating effects to human beings, plants, animals and the environment. Matals are generaly less harmful, although lead is extremely toxic. Hydrogen sulphide is a highly toxic gas. …

Introduction: Photosynthesis is the process by which green plants use the light energy to convert carbon dioxide and water into simple sugar called glucose, which provides a basic energy source for the plant. Photosynthesis occurs in leaves that contain specialized cell structures called chloroplasts. Chloroplasts contain molecules of a green …
