Is a necessary part of the scientific method d. Is often the only way to prove a link between two phenomena e. Can seem to reveal a link between to phenomena when one really does not exist 19.

In other words, the top selfdisciplined students would be in the 5th quintile (or “5” on the axis) below and the lowest self-disciplined students are in the 1st quintile. Answer questions number 21 – 23 using this graph as reference. 21. What is the dependent (response) variable in this observational experiment? a. Final GPA b. Self-discipline c. Both a & b 22. What is the independent (predictor) variable in this observational experiment? a. Final GPA b. Self-discipline c. Both a & b 23. What conclusions can you make from the provided data? a. Self discipline is the primary cause for why a student has a higher final GPA b. Self-discipline is related to obtaining a high final GPA c. Both a & b are true 24. Humans can be_________? a. Carnivores c. Herbivores b. Omnivores d. All of these 25. American Bison consume only plants, so we would say they are ________. a. carnivores c. herbivores b. omnivores d. producers 26.

Technological advancements will allow humans to avoid the consequences of surpassing Earth's carrying capacity. c. The concept of a carrying capacity relates to populations of other organisms but not to human populations. d. If it grows continually, the human population will eventually reach a size too large for our planet's resources. 1. Should a virus be considered a living organism? List three of the characteristics of living things discussed in this course, using a description of virus structure and function explain how this characteristic applies to viruses, and justify whether you thing this means a virus should be considered an organism or not. 2. Explain why mercury levels in a lake may be low enough for you to drink the water safely, yet it would not be safe for you to eat fish caught from the same lake. 3. Draw a biomass graphic utilizing the following organisms: phytoplankton, zooplankton, fish, seal.
