Group of answer choices are smart, social species like vampire bats and parrots, who help non-relatives and get help in return are like ground squirrels who put themselves at risk warning other squirrels, including relatives, of danger like ants, bees and naked mole rats: the workers help their parents and siblings but are sterile 19arrow_forwardSpecies that live in unpredictable habitats are more likely to show traits that are favored by _______. a. r-selection b.

- In populations subjected to high levels of predation a. individuals should invest little in reproduction so as to maximize their survival. b. individuals should produce few offspring and invest little in any of them. c. individuals should invest greatly in reproduction because their chance of surviving to another breeding season is low. d. individuals should stop reproducing altogether.arrow_forwardWhich of the following is NOT an example of an r-selected population? Select one: a. Mosquito lifespan is between 42 and 56 days for females and 10 days for males. b. Minnows spawn 16 to 26 times per year, yielding up to 10 000 eggs per female. c. Houseflies are very tolerant of a wide range of environmental conditions and thus have a broad range of habitat. d. Algae are capable of reproducing asexually and sexually to take advantage on the conditions of the environment.arrow_forwardWhich of these outcomes are examples of reproductive isolation? Select all that apply. Individuals of different species are physically compatible and can engage in sex Hybrid individuals cannot produce offspring Hybrid individuals or their offspring have similar fitness to the original species Reproduction occurs at different times Mating occurs but fertilization does not occurarrow_forward
- Which of the following is associated with the reproductive potential of a species? a. few offspring b. many offspring c. semelparity d. fecundityarrow_forwardBASED ON THIS GRAPH: A small community that is heavily infested with mosquitoes was sprayed weekly with the insecticide DDT for several months. Daily counts providing information on mosquito population size are represented in the graph below. Provide a biological explanation for the changes in the mosquito population over time. Use the terms: insecticide resistance/resistant, natural selection, favorable trait, reproduce, mutation/sexual reproductionarrow_forwardPopulation divergence occurring as a result of females in a species consistently choosing males of a particular color is an example of ecological speciation Haldane's Rule genetic drift sexual selectionarrow_forward
- Which is an example of disruptive selection? Group of answer choices Drug resistance increases with each generation; the resistant bacteria survive, and the nonresistant bacteria get killed off. Swiss starlings usually lay four or five eggs, thereby increasing their chances of more offspring. Over time, Equus developed strength, intelligence, speed and durable grinding teeth. Panay island snails mainly have two different phenotypes, black and white shells.arrow_forwardSelect the three conditions necessary for natural selection.
