Textbook Question
Chapter 14, Problem 1AAATB
Unless handled properly by living systems, oxygen can be quite damaging to cells. Imagine an ancient nucleated cell that ingests an oxygen-using bacterium. In an environment where oxygen levels are increasing, why might natural selection favor a eukaryotic cell that did not digest the bacterium but instead provided a “safe haven” for it?

You are discussing the choice of the “oil-eating” bacteria that you will use to clean the affected area from the oil spill and your team wants to know whether the Kalba sea constitutes a natural habitat for these bacteria.
Formulate a hypothesis stating why or why not the Kalba sea area can be considered a natural habitat for such bacteria. Support your answer by discussing the role of evolution in contributing to the survival and thriving of “oil-eating” bacteria. Explain how and why these bacteria acquired these characteristics

- Which statement best explains why a third domain, Archaea, was added to the original two domains of Bacteria and Eukarya? Question 10 options: Scientists discovered that eukaryotes are unicellular. Scientists discovered that some prokaryotes live in extreme environments. Scientists discovered that eukaryotes have cell walls. Scientists discovered that some prokaryotes have cell walls.arrow_forwardYou discover a new species of bacteria that grows in aquatic environments with high salt levels. While studying these bacteria, you note that their internal environment is similar to the salt concentrations in their surroundings. You also discover that the internal salt concentrations of the bacteria change as the salt concentration in their environment changes. The new species can tolerate small changes in this way, but dies from large changes because it has no mechanism for altering its own internal salt levels. What type of homeostatic mechanism is this species using to regulate its internal salt levels? regulation integration assimilation conformationarrow_forwardWhich of the following statements supports the concept of the endosymbiotic theory? A. Proteins may be trafficked within the endomembrane system. B. Ribosomes are present in the cytoplasm of prokaryotic cells and eukaryotic cells. C. Chloroplasts have many features in common with bacteria. D. Mitochondria can fuse together to form larger organelles within eukaryotic cells.arrow_forward
- Name of the group of microorganisms that completely changed the evolution of life on Earth. - Why can we say that this group contributed to the delimitation of the limits of life? What is their ecological role? - How did these organisms contribute to the evolution of eukaryotic cells and metabolisms? - How did these organisms contribute to the establishment of life in extraterrestrial (out-of-water) environments?arrow_forwardWhat are the eons in which the following events occur? Origin of Earth. Oxygen appeared in the atmosphere Prokaryotic cells Single cell eukaryotes Multicellular eukaryotes Animals Plantsarrow_forwardHere is the question: What was the likely source of the raw material incorporated into the first life forms? I believe it is carbon, but I don't know why it is carbon. What I mean is, why is carbon considered the thing that makes something alive? Why are eukaryotes and prokaryotes simply considered alive just because they have carbon. Would that mean that carbon is alive because carbon has carbon? I would appreciate an anwser because I'm really trying to understand everything I run across. I love educating myself and I'm on a quest for knowledge. Thanks guys!arrow_forward

What advantages and disadvantages are there to an all brain/all muscle body plan? Would this organism benefit from specialized tissues? Why or why not? Consider actual organisms that may be similar in nature with a limited number of specialized tissues/cells. Would you be worried about this organism causing global extinction? Why or why not? Why do you think that the biologist consultant who worked on this film chose an organism which has uniformity in the tissues? Imagine a re-make of this movie.
