Textbook Question
Chapter 24.1, Problem 2CC
WHAT IF? Ø Suppose two bird species live in a forest and are not known to interbreed. One species feeds and mates in the treetops and the other on the ground. But in captivity, the birds can interbreed and produce viable, fertile offspring. What type of reproductive barrier most likely keeps these species separate in nature? Explain.

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.
Please solve
Is this correct??? or is it the other way around

- hi favor to type not handwritten, I can't understand some of the handwritings. thank you!arrow_forwardPlease help me and explainarrow_forwardIti do a cohort study on some new cute animal, and I discover that most of the individuals die at a relatively young age, and only a few live close to the maximum age for the species, what would you predict about the reproductive strategy of this species? O They probably produce relatively few offspring and invest a lot of parental care into each offspring. O They probably produce a lot of offspring, and invest a lot of parental care into each one. O They probably produce a lot of offspring but do not invest much parental care in any individual offspring O They probably produce offspring only after individuals manage to live to close to their maximum agearrow_forward

- I 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_forwardIl Pause e000 What type of reproductive strategy is shown in the model and what is an evolutionary disadvantage of it? O A. Asexual reproduction; organisms that utilize this strategy have increased genetic diversity which increases their ability to adapt to frequent changes. B. Sexual reproduction; organisms that utilize this strategy have increased genetic diversity which increases their ability to adapt to frequent changes. C. Sexual reproduction; organisms that utilize this strategy lack genetic diversity which limits their ability to adapt to frequent changes. D. Asexual reproduction; organisms that utilize this strategy lack genetic diversity which limits their ability to adapt to frequent changes. 757 PM 日 3/22/202 日 e Type here to searcharrow_forwardTopic: 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…arrow_forward
