Veterans and Agent Orange: Health Effects of Herbicides Used in Vietnam : Committee to Review the Health Effects in Vietnam Veterans of Exposure to
Product Description
Have U.S. military personnel experienced health problems from being exposed to Agent Orange, its dioxin contaminants, and other herbicides used in Vietnam? This definitive volume summarizes the strength of the evidence associating exposure during Vietnam service with cancer and other health effects and presents conclusions from an expert panel…. More >>
Anyone know anything about PHOTOSYNTHESIS?
The test-tubes shown were set up by a student to test the effect of light on the process of photosynthesis. All test-tubes contain water and bromothymol blue. (note that bromothymol blue is a chemical indicator that changes colour from blue to yellow in the presence of carbon dioxide.) The student used a straw to bubble carbon dioxide gas through each test-tube until the mixture of water and indicator turned to yellow. Equal-sized pieces of freshwater weed were added to test-tubes A and B. The test-tubes were stoppered, and black plastic was wrapped around test-tube B. All test-tubes were exposed to a light source for a period of 24 hours.
test-tube A: with aquatic plant
test-tube B: with aquatic plant and black plastic wrapped around
test-tube C: with light source
QUESTIONS
- Which test-tube represents the control? Explain.
- What hypothesis was the student testing?
- Describe the colour change, if any, in each test-tube after 24-hour period that would support the hypothesis. In each case explain the expected results.
If anyone can answer any of these questions, it would be greatly appreciated.
