Suppose you are a biologist trying to discover how DNA copies itself. You grow cells in a culture that contains a special isotope of nitrogen, N-15, which will become part of any new DNA the cell makes. After one generation, you analyze the DNA and find that all the DNA has N-15. You then take those cells and grow them for another generation in a culture with the normal isotope of nitrogen, N-1. You know half of the DNA has only N-15 and half has only N-14. What can you infer from this information about how DNA replicates? Explain your reasoning.

What is a negative externality? Give an example of something with a negative externality and what that negative externality is. Does the externality arise from under- or over-production by the market?  (2pts.)  Using your example of a negative externality, explain why a tax or government regulation might help the economy to reach an efficient production point. (2pts) What is a positive externality? Give an example of something with a positive externality and what that positive externality is. Does the externality arise from under- or over-production by the market?  (2pts.)  Using your example of a positive externality, explain why a government subsidy might help the economy to reach an efficient production point.

IMPORTANT: Keep an eye on the camera view popup window Near the bottom right corner of your Canvas window, you should see a popup window showing your camera view. Make sure to leave that window visible throughout your proctoring session. Do NOT minimize it (if you inadvertently do so, then you can restore it by clicking on “Webcam” on the Honorlock toolbar located at the bottom of the testing window) or obscure it, and continue to ensure that your camera view properly shows all the required items (both hands, exam papers, your face profile, etc.). While some violations may be flagged immediately (e.g., your face not being visible), the system will NOT alert you to most types of violations during the session – instead, those will be flagged during the review of the session’s recording conducted by the proctor and/or the professor. IMPORTANT: Keep an eye on the Canvas timer 3 hours and 15 minutes are allocated for this exam on Canvas, but you must finish writing within 3 hours, with the remaining 15 minutes used for scanning and submitting your work. On the right side of the Canvas window, there is a timer showing “Time Running”. Do NOT hide that timer. Before the timer reaches 15 minutes, you must click on “FINISH UP”, and then the “Next” button below. There will be no separate alert from the system during the session – if you finish up late, then your session will be flagged when the session’s recording is reviewed. Start your solution to each problem on a new page. Remember: you must finish the exam before the timer reaches 15 minutes!     Start your solution to each problem on a new page.
