Assignment 2: The Scientific Method (online lab) http://www.mhhe.com/biosci/genbio/virtual_labs_2K8/labs/BL_01/index.html Objectives: Scientific Method in Experiments
In this lab you will apply your knowledge of the scientific method in a laboratory setting. You will also demonstrate the use of experimental terminology and design.
General Instructions:
1. Read through all of these instructions before beginning!
2. Go to http://www.mhhe.com/biosci/genbio/virtual_labs_2K8/labs/BL_01/index.html
3. Read the Greenhouse Manual that first appears when you open this webpage. (Note: Once you close the manual window, you can refer back to this information as the Greenhouse Handbook on the shelf.)
4. Read …show more content…
Describe the effects of the different levels of ECB infestations. Were all corn varieties equally effective at controlling the ECB? How do you know?
They all reduced the amount of kernels in the yield. All of the varieties were not equally effective, because the average yield was different every time.
2. If there was no ECB infestation in a certain year, would a farmer gain or lose financially by planting Bt corn? Explain why.
Then one of the 2 bt varieties (bt 123) would not give a good yield, but the other bt variety would give a really good yield.
3. If there was ECB infestation in a certain year, would a farmer gain or lose financially by planting Bt corn? Explain why.
It would depend on the level of ECB infestation. Both levels would lose but if the level of ECB infestation was high, a farmer would lose a lot more that if it was low.
4. What might happen if ECB became resistant to Bt?
Then over many generations there will be more survivors, and the survivors will be highly resistant to …show more content…
Discuss possible benefits and drawbacks of a transgenic organism such as Bt corn.
Benefits:
1. Whomever is growing the corn would not have to pay for pesticides.
2. The yield would increase.
3. A farmer would be in a better financial position.
Drawbacks:
1. The pest insects would, over time become resistant to it; causing more problems to the corn, so the yield would
