Biology Dissolved Oxygen and Aquatic Primary Productivity Purpose: To measure and analyze the primary productivity of natural waters of laboratory cultures using screens to simulate the decrease of light with increasing depth. Background: Dissolved oxygen (DO) is how oxygen is measured. Oxygen is required in cellular respiration‚ so it is very important for aquatic life. When more oxygen is consumed than is produced‚ dissolved oxygen levels decline and some animals could die if they do not move

Water is a chemical compound with the chemical formula H2O. A water molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure‚ but it often co-exists on Earth with its solid state‚ ice‚ and gaseous state (water vapor or steam). Water also exists in a liquid crystal state near hydrophilic surfaces. Water is considered a purifier in most religions. Major faiths that incorporate ritual washing (ablution) include Christianity

of an Unknown Liquid (2-butanol) Through Fundamental Analysis Lee Billips Department of Chemistry‚ Shippensburg University‚ 1871 Old Main Drive. Shippensburg‚ PA‚ 17257. Abstract: The identification and characterization of unknowns are an important part of organic chemistry. It is fundamental to know experimental methods to deductively identify compounds (1) . The determination of unknown #6 (2-butanol) was identified by a series of test; first taking the boiling point (94-96 C)‚ performing

We can sell it now for 230‚000; in two years it will probably be worth 90‚000. The new machine will save us 125‚000 per year in operating costs. The tax rate is 38% and the discount rate is 14%. Suppose we recognize that if we do not replace the computer now‚ we will be replacing it in two years. Should we replace now or should we

1. Using figure 4 only‚ comment on the characteristics on the urban landscape shown. Suggest how it could be improved. (7 marks) Using figure 4‚ it would appear that densely built shacks – which also appear poor quality - are evidence of shanty town development. Because this area appears so tightly built together (and therefore isolated from the rest of the city)‚ as shown in the bottom of the photograph‚ it will likely have contributed issues such as poor sanitation – whilst also suffered from

Early History of Electric Power Date Event Pictures 1800-1819 Early electric experiments were performed with DC. In 1800‚ Alessandro Volta published a description of a silver/zinc battery‚ acknowledging that he did not know how it worked. In 1807‚ Humphry Davy constructed a practical battery (the picture will be immediately familiar to anyone who works with UPS systems)‚ and demonstrated both incandescent and arc light. • Volta’s famous bi-metalic frog twitch (I did this one myself as a boy..

Question: Do all liquids diffuse in the same way? Purpose: The purpose of this experiment was to find out if all liquids diffuse in the same way. Hypothesis: If different liquids diffuse‚ then the process will not be the same because liquids are made up of different molecules‚ with different densities‚ the diffusion will take longer/shorter than others. Materials: 1 plastic dropper with rubber top (medicine dropper) 3 glass beakers (400mL) 1 graduated cylinder (500mL) 4 drops of red
