- Q1In the 1940s, the scientist J. B. S. Haldane linked many human red blood cell disorders with the tropical regions where malaria occurs. Haldane hypothesized that the widespread presence of these red blood cell disorders as well as traits that protect individuals from malaria were the result of natural selection. Haldane’s hypothesis was later confirmed by the research of A. C. Allison. The resistance to malaria carried by individuals in areas where malaria is widespread is the result of —a vaccine against malariathe individuals’ behavior in avoiding those with the infectionantibiotic medicationsthe individuals’ genetic composition30sB.7.E: Adaptation & Diversity
- Q2The table shows the survival rate of two types of beetles in the same environment over a period of three years. Which statement about the beetles in this environment is best supported by the data?Green beetles are more fit for the environment than brown beetles areBrown beetles undergo a greater number of unfavorable mutations than green beetles doBrown beetles have a shorter life cycle than green beetles haveGreen beetles have a greater gene frequency among their population than brown beetles have30sB.7.E: Adaptation & Diversity
- Q3A prey population consists of individuals with a variety of running speeds. The adaptation that allows some of these animals to run fast would be an example of natural selection if it helps them —survive and undergo mutations in their DNAproduce offspring that run at average speedslower the mortality rates of the populationreproduce and increase the frequency of their genes in the population30sB.7.E: Adaptation & Diversity
- Q4Nudibranchs are marine gastropods that lack shells. Many of these gastropods retain the foul-tasting poisons of their prey and secrete them when threatened. The bright coloration of the nudibranchs warns predators to avoid them. Based on this information, how has adaptation allowed marine gastropods to be successful without a shell?They have bright colors that attract a mateThey find enough food as they move through the marine environmentThey blend in with their environment to hide from their predatorsThey are not attacked by most predators and are able to reproduce successfully30sB.7.E: Adaptation & Diversity
- Q5In the European roe deer (Capreolus capreolus), implantation of embryos after breeding is delayed. The deer breed in July or August but do not give birth until the following May or June. From summer to late December, the embryo rests in a state of dormancy as a 30-cell blastocyst. In late December or early January, the embryo sends a signal that causes the female to release hormones, allowing the embryo to continue to develop normally. Why is delayed implantation an advantageous adaptation for the European roe deer?Delayed implantation allows the mother to continue to breed with other malesDelayed implantation enables the female to give birth to more fawns each yearWithout delayed implantation, the fawns would be born in the winter when food is scarce and the weather is harshWithout delayed implantation, the females would not be able to carry a pregnancy to full term45sB.7.E: Adaptation & Diversity
- Q6Plants have developed many methods of seed dispersal. The table below shows seeds of two different plants. How has the seed dispersal method developed by these plants given them a reproductive advantage?The method reduces the plants’ need for water and other nutrientsThe method reduces the chance that herbivores will consume the seedsThe method lengthens the life cycle of each of these plantsThe method ensures that offspring will be dispersed and reduces competition for resources30sB.7.E: Adaptation & Diversity
- Q7Scientists estimate that there are more than 20,000 species of ants. The species range in size from 1 mm long to 38 mm long and live in most environments. The diets of ants range from flowers and seeds to fluids from their own larvae. Ants have been able to successfully inhabit so many different environments because their populations have been able to —fill niches usually occupied by mammalsoccupy habitats that have no other life-formsadapt to a variety of habitats and food sourceshybridize with other species of insects30sB.7.E: Adaptation & Diversity
- Q8In Madagascar scientists have discovered a moth, Xanthopan morganii praedicta, that has a 30.5 cm proboscis and feeds from and pollinates Darwin’s orchid, Angraecum sesquipedale. The orchid has a nectar-producing tube that is 27.9 cm long. How is the moth’s proboscis size an adaptation for its environment?The moth can avoid larger animalsThe moth has time to feed during the dayThe moth has little competition for foodThe moth can pollinate other flowers30sB.7.E: Adaptation & Diversity
- Q9Some organisms have genes that improve their ability to survive and reproduce. If the genes also help their offspring survive and reproduce, then which of the following will most likely increase?The frequency of the genes in one individualThe number of genes in one chromosomeThe frequency of the genes in the populationThe number of genes in the species30sB.7.E: Adaptation & Diversity
- Q10A harmless scarlet king snake and a venomous eastern coral snake have similar band patterns, as shown below. For the scarlet king snake, the adaptation of having a banding pattern like the eastern coral snake’s is known as mimicry. The outcome of this adaptation in the scarlet king snake is to —make it easier for the scarlet king snake to attract preyprotect the scarlet king snake from predatorsallow the scarlet king snake to blend in with its environmentmake it easier for the scarlet king snake to interbreed with the other snake30sB.7.E: Adaptation & Diversity
- Q11The white cattail is a hybrid species of plant that is a result of the cross between the broad-leaved cattail and the narrow-leaved cattail. Over time, the white cattail has established itself in the wetlands of Midwestern states. Which of these explains the success of the white cattail?Hybrid species display more adaptations due to their reduced genetic diversity.Inherited traits passed on from parental generations make hybrid species more susceptible to disease.Favorable genes from parental generations provide advantageous characteristics to the hybrid species.Hybridization produces offspring traits that allow different species to survive in extreme environments.60sB.7.E: Adaptation & Diversity
- Q12Adaptations that result from natural selection are expected to increase the fitness of an organism. In terms of natural selection, which of the following best describes fitness?Being able to survive long enough to reach the adult stageBeing able to escape from predatorsBeing able to survive, find a mate, and produce offspringBeing among the strongest organisms in a population60sB.7.E: Adaptation & Diversity
