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.

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 of the following is an example of sympatric speciation?Group of answer choicesA population of butterflies prefers oranges. At some point, part of the population develops a preference for bananas. Eventually, the two groups no longer interact to the point that they no longer breed.A population of squirrels is split when a valley is formed, splitting their habitat into two. The valley prevents the squirrels on both sides from meeting and interbreeding.Two populations of fish compete for the same resources in a pond. After several years, the two populations of fish begin mating with one another and produce hybrids.None of these
