Bio unit 3 pt 4 Questions and Answers Already Graded A Select only the best answer. The moth was harder for predators to see Select all that apply. 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? 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? the peppered moth would be less camouflaged (easier to see) Choose one hypothesis. 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? the typica form became less frequent Select only the best 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. How many years into the future does this simulation go? 100 How many generations have passed by the time the simulation is complete? over 100 Which type of moth is currently the most common in the population? white Which moth variety is the least common in the population? 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. Fill in the blanks to summarize the effects of increasing the number of factories. factories increase soot become darker Do you want to know what else you can control? yes Alright, what do you want to know more about? adding predators Once you're ready to move on, set the predation rate to 25%, play the simulation, and then hit "Next". Fill in the images to complete the story below. 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. What happens to the number of black moths? 184 Fill in the images to complete the story below. 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? 630 447 71 85 What percentage of the moths were carbonaria forms? 85 If all of the carbonaria moths that were not recaptured were eaten, what percentage of the carbonaria forms survived? 28 Select only the best response. was supported Match the graphs to the form of the peppered moth that would exhibit the change shown in an industrial area. 1. first graph= Insularia 2. second graph= Typica 3. third graph= Carbonaria Select all that apply. 1. The carbonaria (black) form became less frequent.2. The typica (white) form became more frequent. According to Kettlewell's experiment, which of the explanations below most likely contributed to the decline of the darker-colored moths? Less soot in the air produced lighter trees, making the darker moths stand out. Should this study have even been questioned? Select only the best answer. Yes. Scientific studies should be able to stand up to scrutiny. What should be done to address these concerns? Select only the best answer. Further studies Remembering that Kettlewell's hypothesis was that birds would prey more on forms which stood out in the environment, what did Majerus' study say about Kettlewell's initial hypothesis and conclusions? The criticism was valid or justified. Kettlewell's conclusion was supported. How many rabbits are there at the beginning? How many of those rabbits are female? If the female has a 12-kit litter, how many rabbits are there after 30 days? If half the kits are female, how many females are there after 30 days? Before the first kits are mature and able to have children, the original female can have five litters. How many rabbits would there be with the 2 original rabbits and the five 12-kit litters? 2 1 14 7 62 enter only a number 146 enter only a number 302 Enter only one number in each blank. 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. 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? 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? It starts fast, slows down, then levels out. What do you think the horizontal line on the graph represents? Select only the best 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. 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. predation Which trait represents an adaptation for the hummingbird? Select only the best answer. long
