Chapter 14, Problem 7CT
Corals are colonial marine animals that feed by filtering small microbes from seawater in tropical oceans worldwide. Biologists have discovered that the cells of most corals are hosts lo microscopic algae called zooxanthellae. Design an experiment to ascertain whether corals and zooxanthellae coexist in a mutual, commensal, or

A group of environmentalists is studying the effects of recent commercial zoning to wildlife acreage on the biodiversity of a rural county. The group noted a steady decline in the population of animals, while bacteria and other protists remained constant. Which statement best discusses the reasons for the steady decline of animals as opposed to the protists?
A. Bacterial growth is usually not affected by environmental changes because of asexual reproduction.
B. The animals could not adapt to the new environment.
C. Bacteria lived in areas that were not affected by the zoning
D. The animals became susceptible to human and environmental harm.
The following are actual mutualistic partnerships that involve a protist and a host organism; which
is the exception?
Trichomonas and humans
Cellulose-digesting gut protists and wood-eating termites
Protists living in hypersaline /anoxic waters always associated with bacteria
Algae and certain foraminiferans
Photosynthetic dinoflagellates and reef-building coral animals

- In the early 1930s, G. F. Gause carried out a series of experiments using two species of ciliated protists (Paramecium), which are single-celled eukaryotic protozoans. The protists were cultured together and separately, with the bacteria being the single food source. The results are shown in the figure below. (a) Based on figure, identify and explain the interaction that is taking place between P. caudatum and P. aurelia. (b) Clam shrimp, a natural predator to P. caudatum, is introduced to the culture containing both P. caudatum and P. aurelia after 24 days. Predict the impact that the clam shrimp will have on the culture and the populations. Justify your prediction.arrow_forwardWhy do hydras have varying colors?
