Students have asked these similar questions
Organisms that interact serve as agents of _________on one another. This results in___________ , which is the process by which species evolve adaptations to one another.
In a population of amphipods(small aquatic crustaceans), individual choose mates that have similar body size to themselves. This viloates the assumption of ______________ because an evolutionary mechanism, __________________, is operating in the population. ( name the relevant Hardy-Weinberg assumption and the evolutionary mechanism)
Which of the following best explains the connection between increased competition and the evolution of a species by natural selection?
Individuals migrate to another area in order to avoid competition for limited resources in the current ecosystem.
Individuals that have traits that allow them to outcompete others survive better and produce more offspring.
Individuals must become stronger to compete for resources, and this increased strength is passed on to the next generation.
Individuals that must compete for limited resources are more likely to have diseases that cause mutations.

- The process in which populations accumulate adaptations over time to become more suited to their environments is called ____________ . It is considered the unifying concept of ____________ , which is the study of life.arrow_forwardImage Source: Leigh Torres, Oregon State University Every year, gray whales migrate from feeding grounds in the Gulf of Alaska to breeding grounds off the coast of Mexico. Marine biologists are especially interested in monitoring the population of 'resident' gray whales off the Oregon Coast who skip this journey and instead spend much of the time in cooler waters. Whales have distinct markings on their flukes (i.e. tails) that can be used to identify individuals. Researchers catalog 23 unique flukes during the first week of May. During June, they resample the same area and find 39 total whales, of which 5 were already cataloged. Using the mark-recapture method, how many resident whales make up this resident population? Record your answer to the nearest whole number.arrow_forwardIn a species of water snake has populations on the mainland and on an island, snakes are regularly washed from the mainland to the island where they become part of the breeding population on the island. For the island population, this violates the assumption of ______________________ because the evolutionary mechanism of________________ is present.arrow_forward
- A niche is loosely defined as an organism's role in its environment, which can include factors like, feeding preference, nesting behaviors, mating behaviors, method of obtaining prey, and local habitats. Considering Gause's law, conduct research on the California Red Legged Frog and the Northern Pacific TreeFrog (use wiki or other google search). Create a chart that compares the two with regard to their niche or their lifestyle that may explain how these two native frogs have evolved to coexist in the same ecosystem.

Keeping Gause's law in mind, do some research on the California red-legged frog and the North Pacific tree frog (use wiki or another Google search). Create a chart comparing the two with respect to their niche or lifestyle that can explain how these two frogs can co-exist in the same ecosystem.arrow_forwardMale frogs commonly attract females of the same species using a unique, species-specific call (or "song"). Mónica, an ecologist, notices that there are two closely-related species of frogs living in the pond in her backyard. However, these species never interbreed because it appears that females are only attracted to the call of their own species. This is an example of _________________. a. Ecological isolation b. Hybrid inviability c. Gametic isolation d. Transpecies isolation e. Behavioral isolationarrow_forward
- on the african savanna warthogs regularly visit a group of banded mongooses. the warthog lies down and the banded mongooses pick off parasites and bugs off of the warthog. the end result is the band mongooses get a free meal and the warthog gets cleaned. what kind of species interaction is this and why?arrow_forwardYou 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…arrow_forwardRead this quote from Charles Darwin (from Origin of Species). What is he describing? "Thus, I can understand how a flower and a bee might slowly become, either simultaneously or one after the other, modified and adapted to each other in the most perfect manner, by the continued preservation of all the individuals which presented slight deviations of structure mutually favorable to one another." An interaction network. A predator/prey cycle. O Coevolution. An obligate mutualism.arrow_forward
- Imagine that you are a scientist studying species interactions in Kruger National Park, South Africa. Today, you are observing a pride of lions in the southeast quadrant of the park. Two lionesses brought down a large adult wildebeest. The adult females fed for approximately 20 minutes. Their cubs appeared interested in feeding but were largely kept away from the kill by the adult lions. A clan of hyenas drove the lions from the carcasses and fed for approximately 30 minutes. Two male lions drove the hyenas from the carcass, killing a female hyena. The male lions ate most of the kill; vultures fed on remains.1.
