Answer: D Which of the following is NOT one reason why natural selection was not immediately accepted once it was proposed? A. it faced pressure from churches B. it was not 100% accurate, after all C. Lamarck’s blending theory of inheritance was dominant at that time and few people would challenge it D. it was very radical at that time; people didn’t believe they were relatives with monkeys E. it was not complete: it didn’t explain where variation was created Correct Answer: C Which of the following is NOT a type of biodiversity: A. functional diversity B. species diversity C. ecological diversity D. genetic diversity E. organism diversity Correct Answer: E Which of the following is NOT true: A. the higher the genetic diversity, the higher the potential rate of evolution B. the higher the strength of the selective pressure, the higher the potential rate of evolution C. the longer the generation time, the lower the potential rate of evolution D. the larger the population size, the higher the potential rate of evolution E. the lower the reproductive rate, the lower the potential rate of evolution Correct Answer: D Which of the following is NOT a goal of conservation biology?
