4. #1 More Information Feedback Loops.. Positive Feedback ENHANCES a condition. For example:  If polar ice melts then dark ocean water can heat up, so more polar ice melts, so ocean water heats up more, and so on…. Negative Feedback REVERSES a condition. For example:  You are hot; you sweat and it cools your body..  You are hungry; you eat and you are no longer hungry…  You are thirsty; your urine is dark yellow and not much in volume (your body is conserving water)

5. Question 8 The predators that eat the tussock moth will have less food, lowering their population. Then the next level up on the food will have less food, and overall the entire food web will be less healthy because the moth is missing. The insecticide will kill other insects besides the tussock moth, which will eliminate food sources from the food web for upper level consumers, leading to a less healthy food web overall.

6. Question 8 One unintended consequence of using insecticides is that they will kill off another forest insect, the crane fly, which keeps mosquito populations down. This will damage the food web because organisms will be less healthy from being fed on by mosquitoes. Another unintended consequence of using insecticides is that they will kill pond insects. This will reduce the food supply for fish and that will provide less food for organisms higher on the food chain. Etc., etc.

7. Questions 9-11 9. D (the parents only have recessive alleles, so babies do, too.) 10. C 11. B

8. Question 12 One reason that the greenhouse model is unreliable is that greenhouses trap heat, so the air temperature would not be similar to natural air temperature that moths live in. Therefore, you couldn’t truly gauge the affect of normal air temperature changes on moths. Another reason it is unreliable is there is no weather conditions inside a greenhouse, like wind and precipitation, which would naturally change the weather conditions outside. Therefore, the moths aren’t exposed to their normal air temperature fluctuations and their survival can’t be accurately studied.
