Red queen hypothesis D. unpredictability model
Which of the following is not a mutualistic relationship? a. a shark using an aquatic cleaning station b. a helminth feeding from its host c. a bumblebee collecting pollen from a flower d. bacteria living in the gut of humans
An experiment was designed to analyze the metabolic rate of several bird species. A single bird was isolated in a chamber, and the amount of respired carbon dioxide was measured for 30 minutes. During this time, the heart rate of the bird was also measured. The table shows the average amount of carbon dioxide after three trials. Based on this data, which of the following species would you predict to have the smallest body mass? A - All species will have equal masses. B - Species A will have the smallest body mass due to its heart rate being the lowest. C - Species A will have the smallest body mass due to its exhaled carbon dioxide being the lowest. D - Species D will have the smallest body mass due to its exhaled carbon dioxide and heart rate being the highest.
Which of the following statments about properties of life is false? A) Organisms have the ability to respond to stimuli from the enviroment B) Orangisms have unchanging, constant internal enviroment C) Organisms have the ability to take in energy and use it D) Organisms have the ability to produce
Which of the following statements is not true of an ecological niche?a. A niche includes the physical environment, such as climate and water availability.b. A niche includes predators and parasites.c. Niche overlap may help to drive evolution.d. Two species cannot have overlapping niches.
Which 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.
