- Which of the following traits is more associated with an Opportunistic (Equilibrial) species? Which of the following traits is more associated with an Opportunistic (Equilibrial) species? A. Short maturation time B. Producing offspring at many different times over the course of life C. Producing a lot of eggs at one time D. High juvenile mortality E. High level of parental carearrow_forward1. Sea urchins are broadcast spawners that release clouds of sperm/eggs into the water column. However, the ability to successfully fertilize the egg by the sperm is restricted to very specific gametic proteins that inhibit cross species fertilization. This is an example of a a.

- A. In terms of the barriers in place that keep species separate, explain whether song recognition is a prezygotic barrier or a post-zygotic barrier. B. Explain which type of isolating mechanism this wouldbe once you determine the barrier type. C. Discuss why song would be a barrier to mating with another species and having the incorrect song might change your fitness potential.arrow_forwardWhich of the following terms best describes the biological scenario where species that look similar in allopatry look different in sympatry? a. Character displacement b. Tempo c. Fusion d. Post-zygotic barriersarrow_forwardWhich of the following situations has revealed that mutualistic interactions can evolve from prior parasitic relationships? A. Yucca plants are pollinated only by moths of the genus Tegeticula; however, some of the moth species 'cheat" by laying eggs on seeds without pollinating the plant. B. Large-sized lice of the genus Columbicola tended to live on larger species of pigeons. Body size matching had a significant effect on the ability of lice to escape defensive preening by the host bird. C. The nonvenomous yellow-eyed salamander has the same coloration as the toxic California newt. Related nontoxic salamanders which do not mimic the newts are prone to attacks by predators. D. Glochidion trees and Epicephala moths are in an obligate mutualism with each other. Significant cospeciation led to an increase in diversity of the two species.arrow_forward
- Multiple choice (one answer is correct) a.

Giraffes are approximately 6’ tall and weigh 150 lbs at birth. b. Wild giraffes begin mating at 6-7 years of age. c. Newborn giraffes are capable of coordinated walking within an hour of birth, and running within 24 hours of birth. d. Giraffes rarely give birth to twins.arrow_forwardAn orchid species has flowers that resemble and smell like female bumblebees. The flower attracts male bumblebees, which attempt to mate with the flower. They get a package of pollen attached to their body, which they then deliver to another orchid flower of the same species. Which of the following statements about this is correct? a. this is an example of mullerian mimicry b. this is an example of batesian mimicry c. this appears to be a different type of mimicary rhat does not fit either mullerian or batesian model d. no answer text providedarrow_forward

Group of answer choices a. high levels of sexual selection b. external fertilization c. carnivorous larvae d. type III survivorship curve e. cytoplasmic determinantsarrow_forwardWe learned from hermaphroditic snails in New Zealand and C. elegans that populations that are undergo both sexual and asexual reproduction in the same population can alter the frequency of outcrossing resulting in changes in genetic diversity. Identify the statement that accurately reflects a real result. a. Sexual reproduction prevents the ability of snails and worms to coevolve with their parasites. b. Sexual reproduction frequency increases in the presence of a stressor, like pathogens and parasites. c. Asexual reproduction is favored when there are pathogens and parasites in the environment. d. Asexual reproduction enables the Red Queen hypothesis to play out and enable the pathogen to win.arrow_forwardThe twofold cost of sex model by John Mynard Smith explains how - A. asexual females can become predominant in a population. B. anisogamy results in sexual reproduction. C. sexual individuals can produce genetically variant offspring. D. asexual females invest as much in offspring as the sexual females.arrow_forward
