“Watermelon snow” in Antarctica is caused by a species of photosynthetic green algae that thrives in subzero temperatures (Chlamydomonas nivalis). These algae are also found in high-altitude year-round snowfields. In both locations, UV light levels tend to be high. Based on what you learned in this chapter, propose an explanation for why this photosynthetic alga appears reddish-pink.

- Dinoflagellates are unicellular, marine protists. Dinoflagellates are bioluminescent, but only at night. During the day, they carry out photosynthesis similar to other autotrophs. At night, however, they bioluminesce every time they are disturbed. They are often seen in the wakes of ships at night. While the reason for this bioluminescence is not fully understood, many scientists concur that it is a form of self-defense. If small fish begin to feed upon the protists, the protists will begin to bioluminesce. These flashes of light in the dark water can alert larger fish and draw them towards the small fish, upon which they prey. By making the small fish vulnerable, the dinoflagellates are able to protect themselves. Based on the information above, a researcher decides to design an experiment in which she is testing how long it takes for dinoflagellates to recover after different amounts of disturbance. She maintains 10 containers of dinoflagellates with similar temperature, salinity and…arrow_forwardDinoflagellates are unicellular, marine protists.

- Clostridium botulinum is a strict anaerobe; that is, it is killed by the molecular oxygen (O2) present in air. Humans can die of botulism from eating foods in which C. botulism is growing. How does this bacterium survive on plants picked for human consumption? Why are home-canned foods most often the source of botulism?arrow_forwardWhich of the following statements is correct for bothblue-green algae and bacteria ?(a) Both show anaerobic respiration.(b) Both have chlorophyll pigment.(c) Both are devoid of true nucleus.(d) None of the above Please try to break the solutions into as many steps as practically possible and the steps should come one by one and they should be short and crisp and plagiarism-free.arrow_forwardIn 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_forward
