<p><p>Which of the following best describes the principle of evolution by natural selection?</p> <p>A. Individuals within a population are genetically identical and natural selection occurs randomly</p> <p>B. Individuals within a population exhibit genetic variation and those that are best adapted to their environment survive</p> <p>C. Individuals within a population exhibit genetic variation and those that are least adapted to their environment survive</p> <p>D. Individuals within a population undergo genetic mutation and natural selection occurs randomly</p> <p>E. Individuals within a population exhibit genetic variation and natural selection occurs randomly</p></p>

<div>1. Which of the following risks is the result of random variation in the survival and production of offspring and is especially of concern for a small population? <div>A. Genetic drift</div> <div>B. Environmental stochasticity</div> <div>C. Inbreeding depression</div> <div>D. Demographic stochasticity</div> <div><br></div> <div>2. Imagine you are a marine biologist and you want to estimate the population size of sea otters in your study area. Which of the following method would be the best approach to do this?</div> <div>A. Counts</div> <div>B. Mark-recapture</div> <div>C. Quadrat</div> <div>D. All of the above</div> <div><br></div> <div>3. You captured and tagged 15 otters on Day 1. A month later, you resample the area and catch 30 otters, of which 3 are tagged. What is the estimated total population size?</div> <div>A. 30</div> <div>B. 50</div> <div>C. 125</div> <div>D. 150</div> <div>E. 450</div> <div><br></div> <div>4. If you used a mark-recapture approach to estimate the size of an animal population, but the tags were defective and fell off some of the originally sampled individuals, the method would tend to:</div> <div>A. Underestimate the true population size</div> <div>B. Overestimate the true population size</div> <div>C. Either underestimate or overestimate the true population size, depending on how many individuals lost their tags</div> <div>D. None of the above</div> <div><br></div> <div>5. Which of the following affect population size?</div> <div>A. Birth, death</div> <div>B. Birth, death, immigration, emigration</div> <div>C. Birth, death, immigration, emigration, speciation</div> <div>D. Birth, death, genetic drift</div> <div>E. None of the above</div> </div>
