Question

QUESTION 17 A new pest insect species has started attacking plant crops around San Jose. Fortunately, there is a possibility that a new pesticide might be effective. There is a danger, of course, that application of the pesticide may lead to evolution of pesticide resistance in the insects. Which of the following need to be true for this to occur? The population must currently have some individuals that are pesticide resistant. Pesticide resistance must be exaptive. Pesticide resistance must be inheritable. (a) and (c) All of the above. QUESTION 18 A simple survey of natural organisms today shows a range of complexities of functioning eyes, from extremely simple/reduced eyespots and reflecting pigment cups, to the much more complex single-lens chambered eyes and compound eyes. What is problematical about considering the vertebrate single-lens chambered eye the "pinnacle of evolution"? In terms of functionality, every form of the eye, from simple to complex, serves its required function. From an engineering perspective, there are objective a number of objectively better or more complex eye designs than the vertebrate one. Simple eyes could have arisen by chance alone but not more complex ones. All of the above. (a) and (b) QUESTION 19 It is extremely unlikely that humans will have evolved as a result of the COVID-19 pandemic at least in terms of immunity, because: We have not developed a vaccine. There is no inheritable variation in sensitivity or resistance to COVID-19 infection. Social distancing restricts the ability of the virus from spreading to all humans. Humans have mostly stopped evolving. The human population is too large and too widespread to evolve. QUESTION 20 Which of the following facts provides the clearest evidence for common rather than separate ancestry? The coelacanth fish looks almost indistinguishable from fossils in 200-million-year-old rocks Most primates have tails, which seem to be important for their survival Diverse cactus species are found in the American deserts, but none occur in African or Asian deserts Some orchid flowers are very well suited to pollination by particular kinds of insects Whale flippers and dolphin flippers have a similar bone arrangement and are used for a similar function
