Chapter 1.3, Problem 4CC
WHAT IF? Ø In the deserts of New Mexico, the soils are mostly sandy, with occasional regions of black rock derived from lava flows that occurred about 1,000 years ago. Mice are found in both sandy and rocky areas, and owls are known predators. What might you expect about coat color in these two mouse populations? Explain. How would you use this ecosystem to further test the Camouflage hypothesis?

Topic: NATURAL SELECTION ACTIVITY
Simulate a case of natural selection in a predator-prey situation.
STEP 1 Gather your materials. You should have:
. 1 fork, 1 knife, 1 spoon, and a length of tape (each will be used toestablish the distinct predator "feeding apparatuses")· 4 cups (each will serve as a distinct predator's "mouth")· 3 types of prey (such as popcorn, macaroni, and kidney beans)· 1 clearly delineated habitat (such as a table, a box, or a roped-off areaof ground). 1 timer that allows for counting by seconds (such as a watch or cellphone)
STEP 2 Set up the predators. There is variation in predatory feeding apparatuses in this population. You will choose one of the available predator feeding apparatuses: fork, spoon, knife, or four fingers (with your thumb taped to your hand so that you cannot use it). You will also take a cup, which will represent the predator's mouth. Your goal will be to use your feeding apparatus to collect food and put it inyour mouth.
STEP 3 Set up the…

- Q2.16. When heavily armored marine sticklebacks have invaded freshwater lakes where there are no predatory fish, their populations have evolved lighter body armor. Given what you've learned about evolution, which of the following explanations for why this happens is most plausible? O Young sticklebacks only grow heavy armor when they see predatory fish in their environment. O When sticklebacks don't use their armor, it shrinks. Then they pass lighter armor to their offspring. Concentrated pollutants in freshwater lakes disrupt the sticklebacks' ability to grow armor. O Heavily armored fish grow more slowly and breed later, making armor disadvantageous in these lakes.arrow_forwardI need help identifying which assumption of Hardy-Weinberg equilibrium is most affected, then indicating whether what is being described will act to establish or violate equilibrium, and lastly, whether the statement will increase or decrease that population’s genetic variation. Corals synchronize spawning to occur on a single night during a particular tidal event, such as a spring tide. On that night individuals release sperm and eggs into the water, which then form zygotes. Larvae are carried off by currents and settle elsewhere. What assumption is this breeding style affecting and what will it do to VG of that coral species?arrow_forwardEVOLUTION ASSESSMENT - FINCHES Galápagos Ground Finches Between 1973 and 1978, the population of ground finches (a type of small bird) on the Galápagos Islands decreased. Scientists made observations of the population throughout that time period. They recorded and graphed differences in the distribution of traits over time. The two sets of graphs below come from the data they collected.

- 1) Think back to the example of ovenbird evoluon in South America. Ovenbirds are a diverse family of small, insect-eang birds that live mainly in South America. Different ovenbird species have adapted to rocky ocean shorelines, snowy mountains, scorched deserts and tropical rainforests. Like finches, ovenbirds have a variety of beak sizes and shapes, an important indicator of food preference that makes them ideal for studying evoluon. In ovenbirds, "some [beaks] are long and down-curved, like a scythe, for probing into crevices in tree bark and others have short dagger-like bills." What conclusions did the researchers reach? A) ovenbirds are diverse because they do not share any common ancestors B) ovenbirds because successful because they are not native to the area and could easily colonize the area C) birds have different beaks that help them exploit different resources and avoid competition 2) One ant species from Africa is best at competing for space, but is worse at colonizing a…arrow_forwardName: Date: Galapagos Finch Evolution (HHMI Biointeractive) - https://voutu be/mcM23M-CCog ~16 minutes 1.

A recent study showed that the pigmentation pattern used for camouflage is made by an enzyme K. However, it has been shown that, when compared to the Kk individuals, the KK homozygotes would have a higher chance of dying from pigment overdose before growing up, while the kk individuals can easily fall to predation before becoming adults. In fact, when compared to the Kk individuals, the estimated selection coefficients for KK and kk are 0.25 and 0.5, respectively. You are interested in what would happen to these alleles. At present, you have conducted a population survey and have 1000 larvae in your collection. Among them, 360 are KK, 480 Kkand 160 kk. 1)How many larvae would survive to adulthood a) 170 b) 414 c)583 d)750 e)830 2)Following up the previous question, what would be the KK genotype frequency at the adult? a) 0.090 b) 0.270 c) 0.325 d) 0.360 e) 0.529 3)Following up on the previous question,…arrow_forward
- You want to distinguish between two hypotheses to explain the patterns you see: 1) Males not feeding the young is an adaptation to dimorphism 2) If males don't feed the young in a species, it will allow them to become brightly colored To begin to address this question, map the characters changes in dimorphism and males feeding the young onto each of the trees on the previous page.
