Select only the best answer. - Correct answer The moth was harder for predators to see Select all that apply. - Correct answer the luna moth would be easier for predators to see than the peppered moth the predator would eat the luna moth What effect do you think this would have on the trees that the peppered moth rested on? - Correct answer the trees would become darker in color What effect would the change in bark color on the trees have on the ability of the peppered moth to camouflage itself? - Correct answer the peppered moth would be less camouflaged (easier to see) Choose one hypothesis. - Correct answer moth population would be darken in color Given the factory-produced soot that covering most surfaces in industrial areas during the time, what pattern did E.B. Ford most likely notice? - Correct answer the typica form became less frequent Select only the best answer. - Correct answer the white form will form the greatest percentage of the population eaten in industrial areas Select the bar representing the percentage of black (carbonaria) moths in the population. Then select the bars for the grey and white moths to see them highlighted in the population. Hit next once you're ready to move on. - Correct answer How many years into the future does this simulation go? - Correct answer 100 How many generations have passed by the time the simulation is complete? - Correct answer over 100 Which type of moth is currently the most common in the population? - Correct answer white Which moth variety is the least common in the population? - Correct answer black To do this, maximize the number of factories and then press the play button on the timeline below. See how this affects the environment over time Once you're ready to move on, hit Next. - Correct answer Fill in the blanks to summarize the effects of increasing the number of factories. - Correct answer factories

increase soot become darker Do you want to know what else you can control? - Correct answer yes Alright, what do you want to know more about? - Correct answer adding predators Once you're ready to move on, set the predation rate to 25%, play the simulation, and then hit "Next". - Correct answer Fill in the images to complete the story below. - Correct answer white trees, light moth, dark tree Now, recreate the Industrial Revolution by increasing the number of factories to the maximum value. Then press the Play button to see what happens to the number of black, grey, and white moths over the course of 100 years. - Correct answer What happens to the number of black moths? - Correct answer 184 Fill in the images to complete the story below. - Correct answer dark tree black moth lightest moth How many total moths were released? How many carbonaria forms were released? What percentage of the moths were carbonaria? What percentage of the moths were carbonaria? - Correct answer 630 447 71 85 What percentage of the moths were carbonaria forms? - Correct answer 85

enter only a number - Correct answer 146 enter only a number - Correct answer 302 Enter only one number in each blank. - Correct answer 530 830 1202 1646 Take a close look at both the old and new models. Then, using the graphs below, decide which graphs best depict these models. - Correct answer graph a Each environment-organism pair has what is called a carrying capacity, the maximum size of the population that can exist in an environment. What characteristics of the environment might limit the carrying capacity of a population? - Correct answer Food Habitat Water These limiting factors also prevent the exponential growth pattern you saw with rabbits and humans from continuing unchecked. The exponential curve gives way to what is called a logistic growth curve, shown at the right. What do you notice about the growth rate, represented by the slope of the line? - Correct answer It starts fast, slows down, then levels out. What do you think the horizontal line on the graph represents? Select only the best answer. - Correct answer carrying capacity Which of these factors below would be part of a niche but not contribute to environmental carrying capacity? Select all that apply. - Correct answer Predators Competing organisms Which of these was a key selective pressure for the peppered moths studied by Kettlewell and Majerus? Select only the best response. - Correct answer predation Which trait represents an adaptation for the hummingbird? Select only the best answer. - Correct answer long
