AP 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

Alex Melekos English Research Paper Generation Pill The reality of drug abuse in American culture has fueled FDA restrictions and reforms for decades as more information on drug availability‚ distribution‚ and side effects is released to the public. A trending topic that has gained publicity in the past months is the rate at which doctors prescribe opiates. Drugs such as Percocet‚ OxyContin‚ Vicodin‚ and Roxicodone are synthesized medications that doctors prescribe for the relief of pain

from green beans Name: Ashni Couprie and Dennise Susanto Class: 5c Introduction From previous experiments we ’ve learned that salt is extracted from green beans. To be more specific: salt is extracted from when the beans are cooked in water in which salt has been dissolved. This experiment is based upon the osmoses theory. According to this theory the cell walls of the green beans are what we call a semi permeable membrane. This membrane only lets water through and not the substance that is

You might have thanked the trees for giving oxygen but never phytoplankton. What can they do except try to steal the Krusty Krab formula? Well‚ what if I said that without phytoplankton‚ the entire marine ecosystem collapse‚ an increase of 1/3 accumulation of CO2‚ and oxygen drop up to 50 percent in the atmosphere‚ which will lead to human extinction. Sounds dramatic‚ but it is true. I seriously think that we need to care more about these planktons‚ since they are not unlimited in the ocean‚ and

From a chemical perspective‚ what is oxygen? Identify its atomic number‚ the group it fits into OXYGEN in the periodic table‚ its chemical formula‚ its melting point‚ boiling point and state at room temperature. Oxygen is highly reactive‚ nonmetal‚ oxidising agent that readily forms oxides‚ it is an element. By mass‚ oxygen is the third-most abundant element after hydrogen and helium. The Atomic Number: 8 Group: The chalcogen group Chemical formula: 02 Melting
