Document Summary
This exercise allows 35 minutes for 14 questions. Most questions have a straightforward structure with a single correct answer for full marks. However, there are two types of questions in which more that one answer may be correct: Type 1 questions are structured as was shown in lecture 8 with 5 possible combinations of correct answers to choose from (a 1, 2, & 3; b 1 & 3; c 2 & 4 etc. Type 2 questions may have more than one correct answer and you must pick all correct answers to get full marks. Part marks are available but there is a penalty for choosing incorrect answers. (e. g. two correct + one incorrect = 0. 5 marks. ) The anti-retroviral drug azt is effective in treating people newly diagnosed with hiv. However, after hiv patients have used azt for several months, the virus becomes resistant. The miller urey experiment was a huge breakthrough in our understanding of the origins of life.
