Read each of the scenarios below. Then, select the option that best represents a scenario illustrating natural selection.A In a population of birds, those with larger beak sizes are better able to crack open tough seeds, providing them with a food source during periods of scarcity. Consequently, the average beak size in the population decreases.B In a population of flowers, those with a particular color variation attract more pollinators and produce more offspring. As a result, the proportion of flowers with that color variation decreases over generations.C In a population of rabbits, those with longer legs are more successful at outrunning predators and are more likely to survive and reproduce. Over time, the average leg length in the population increases.D In a population of fish, those with brighter colors are more easily spotted by predators, leading to higher mortality rates. As a result, the proportion of fish with bright colors increases over time.

Suppose in a population of a single bird species, natural selection favors medium-sized beaks. Birds with very small beaks cannot break open the seeds they feed on; birds with large beaks cannot reach into the fruit to get the seeds at all. Natural selection in this case results inA.stabilizing selection.B.convergent evolution.C.adaptive radiation.D.disruptive selection.

Natural selection requires genetic variation, competition for limited resources, overproduction of offspring, and unequal reproductive success.The subset of finches that is capable of eating large seeds, while many others eat small seeds, is an example of which requirement?Multiple Choiceoverproduction of offspringgenetic variationunequal reproductive successcompetition for limited resources

Which is a correct statement about the evolutionary changes in the medium ground finch studied by Peter and Rosemary Grant?Multiple choice question.Climatic variation impacts seed size, which is a selective force on the competitive abilities of the birds.Climatic variation impacts seed nutritional content, which is a selective force on hatchling survival.Climatic variation impacts seed size, which is a selective force on beak size.Climatic variation impacts seed size, which is a selective force on the ability of birds to tolerate toxins.

Which changes would most likely limit the growth of a plant-eating animal population? Select four options. The number of predators decreases. Steady rainfall increases the number of plants. A spring freeze kills many plants. The number of predators increases. A harmful plant disease spreads through the area. A harmful animal disease spreads among the population.

Imagine you are studying a population of finches over time and observe an increase in average beak size over many generations. This is an example of ______________ selection.Group of answer choices
