- Why is water measure in pharmaceutical products essential? answer at your own words and answer should be to the point, not any irrelevant wordsRearrange the jumbled letters in each number to form the correct word. The following words are the different stages that are found in the water cycle.Imagine you are testing water samples from a local pond for pollutants. Your lab instructor sees the results of your dissolved oxygen test and remarks that your water sample has the same dissolved oxygen level as water found near the seafloor of a dead zone. What is the dissolved oxygen level of this water sample? 650-700 ppm 350-360 ppm 80-90 ppm 7-9 ppm 2-3 ppm

Which zone has the lowest Dissolved Oxygen? c. Which zone has the highest Biological Oxygen Demand? d. Which zone shows the greatest change in Dissolved Oxygen? Types of organisms Normal clean water organisms Trash fish Fish absent, : (carp, gar. : fungi, sludge (Trout, perch, bass, mayfly, stonefly) Trash fish (carp, gar,: leeches) worms, bacteria (anaerobic) leeches) 8 ppm Dissolved 8 ppm oxygen (ppm) Biological oxygen demand Decomposition Septic Zone Rec very Zone Clean Zone Clean Zone Zone B C 近Distinguish between a transfer and a transformation. Give examples using the hydrological cycleWith the aid of a diagram, propose and explain a pH control system to maintain pH at 5 in a fermentor/bioreactor.
- Mentions the advantages of membrane bioreactors in water treatmentA flask containing an aquatic plant in water is placed next to a light. A sensor that detects the amount of dissolved oxygen is placed in the flask, and the light is set on a timer to run on a 12-hour-light, 12-hour-dark cycle for 48 hours. Explain how the amount of dissolved oxygen will change in the flask during the 12-hour-light cycle Support your explanation using information about the processes that are occurring in the flask.Explain how the amount of dissolved oxygen will change in the flask during the 12-hour-dark cycle.
