In a population of fish, there is substantial variation in fin length phenotype. If a fish is raised in an environment with high predator pressure, that fish will develop a smaller tail at adulthood as long tail: make them easier to catch. If a fish is raised in an environment with low predator pressure, that fish w develop a longer tail as greater length increases swimming speed and the threat of predators is low. Further, eggs from short tailed parents when raised with low predator pressure develop long tails. Eg from long tailed parents when raised with high predator pressure develop short tails. The tail length ifferences observed in this scenario are a product of evolutionary change by natural selection. True False

The rough-skinned newt, which lives in western North America, stores a poison in its skin and is avoided by predators. However, several populations of garter snakes have undergone one or a few mutations that enablethem to tolerate the toxin, and these snakes eat the newts with no ill effects. How has natural selection affected this predator–prey relationship? Based on what you have learned about evolutionary arms races, predict what may happen to the newts and the poison-resistant garter snakes over time.
The evolution of beak size in the various species of Galpagos finches is associated with their (a) songs (b) diets (c) body sizes (d) predators (e) none of the preceding
Among a population of tadpoles, the correlation coefficient for size atmetamorphosis and time required for metamorphosis is −0.74. On thebasis of this correlation, what conclusions can you draw about therelative sizes of tadpoles that metamorphose quickly and those thatmetamorphose more slowly?
Some fish in a murky underground lake have lighter scales than the others. This makes it slightly harder for the lighter fish to escape detection by predators, but most light-colored fish live long enough to reproduce. A natural event separates the dark-scaled fish from their light-scaled cousins, and as a result, a new species of dark-scaled fish emerges. Which statement accurately describes the scenario?
Ancestors of the beach mouse mayhave exhibited variations in their coat color. Because of the prevalence of visualpredators, the better-camouflaged (lighter) mice in the beach habitat may havesurvived longer and been able to produce more offspring. Over time, a higher andhigher proportion of individuals in the population would have had the adaptation of lighter fur that acted to camouflage the mouse in the beach habitat.
You are surveying of the turtle species identifies several breeding populations in different habitats across the island. After a very warm summer of 2020, you observe that the hatchlings from low-elevation nests are mostly males, whereas hatchlings from higher elevations have an equal female-to-male sex ratio. As a bit more background, temperature influences the sex ratio in some turtle species, a phenomenon called temperature-sex determination (TSD). With this knowledge, you hypothesize this new turtle species exhibits TSD, and that eggs incubated at low elevations during the warm year experienced a high enough embryonic temperature to skew the sex ratio. To test this, you collect 20 newly laid eggs in early 2021 & take them back to the lab to conduct an experiment to test your hypothesis that this species exhibits TSD. Assume you know the average nest temperature in the wild, and you have access to multiple incubators Design an experiment to test the hypothesis that this turtle…
Prey animals may use distraction displays when a predator is nearby.What selective pressures do these prey animals exert on predators?Explain why distraction displays may become more convincingthrough evolutionary time.
Conservation biologists have altered the evolution of salmon populations in captive-breeding programs. Wild female salmon tend to produce fewer large eggs because the large eggs contain more nutrients for the off spring, giving each individual a greater chance to survive. After just a few generations, however, captive-bred females now lay greater numbers of small eggs. Suggest a possible adaptive advantage for many small eggs in the captive-bred environment. What would you predict regarding the reproductive success of captive-bred females released in the wild?
Living things that are well adapted to their environment survive and reproduce. Those that are well adapted don't survive and reproducer. An adaption is any characteristics that increase fitness,which is defined as the ability to survive and reproduce. What characteristics of the mice is an adaptation that increased their fitness?
A region of the canary forebrain shrinks during the nonbreedingseason and enlarges when breeding season begins. This change isprobably associated with the annual(A) addition of new syllables to a canary’s song repertoire.(B) crystallization of subsong into adult songs.(C) sensitive period in which canary parents imprint on newoffspring.(D) elimination of the memorized template for songs sung theprevious year.
Almost all birds starved during the dry season depicted here. What type of selection would have been present if only the intermediate-beaked birds had survived (instead of the small- and large-beaked birds)?
Female mimicry by males occurs in many species. For example, in the Broadley’s flat lizard (Platysaurus broadleyi), some males have the brown coloration of females while others are far more colorful (Whiting et al. 2009). Female mimics do secure some matings in the territories of their larger, more colorful rivals. Why are the bigger males (and those of the marine isopod Paracerceis sculpta) ever fooled into tolerating a female mimic? Why do female mimics occur in any species if the mating success of these individuals is lower than that of the bigger territorial males? Don't write from any online source..
