Step by step
Solved in 2 steps
- Which of the following observations constitutes evidence that mitochondria evolved before chloroplasts? Mitochondria are aerobic. Chloroplasts are photosynthetic. Aerobic bacteria evolved before photosynthetic bacteria (cyanobacteria). Some protists have separately evolved their own plastids (chloroplast-like structures) through endosymbiosis of cyanobacteria, or even through endosymbiosis of photosynthetic protists. All Eukaryotes have mitochondria; only a subset of Eukaryotes have chloroplasts.In the domain system of classification, prokaryotes are divided into two domains: Bacteria and Archaea. The two domains differ in all BUT one feature. Which feature do they have in common? A. They both thrive in extreme environments. B. They both have prokaryotic cells. C. They both are able to live only under anaerobic conditions. D. They both have identical cell walls.. Which of the following prokaryotic kingdoms is characterized by the absence of a nucleus, the absence of histone proteins, the presence of fatty acids ester-linked to glycerol in their G-3-P cell membrane, and the presence of enzymes for constructing a peptidoglycan cell wall? kingdom Archaeobacteria kingdom Animalia kingdom Fungi kingdom Plantae kingdom Eubacteria
- Which of the following pieces of evidence could support the endosymbiotic theory if found to be true? Traces of peptidoglycan in the cytoplasm in eukaryotes Presence of rRNA in eukaryotes Presence of 80S ribosomes in eukaryotes The discovery of a unicellular eukaryoteThe first appearance of free oxygen in the atmospherelikely triggered a massive wave of extinctions among theprokaryotes of the time. Why?Which of the following organisms is a prokaryote? fungus algae protozoa archaea both archaea and protozoa
- 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.In the domain system of classification, prokaryotes are divided into two domains: Bacteria and Archaea. The two domains differ in all BUT one feature. Which feature do they have in common? Question options: They both have identical cell walls. They both have prokaryotic cells. They both thrive in extreme environments. They both are able to live only under anaerobic conditions.Which of the following do not belong to domain Archaea? (a) prokaryotes that produce methane from carbon dioxide and hydrogen (b) thermophiles (c) halophiles (d) bacteriophages (e) prokaryotes with cell walls that lackpeptidoglycan
- Which of the following provide evidence for an endosymbiotic origin of mitochondria and chloroplasts? Choose all the correct statements. Group of answer choices They are about the same size as free-living cyanobacteria and alpha proteobacteria. The nuclear membrane of eukaryotes is similar to the archaean cell membrane. Organelle genes are often more similar to bacterial genes than those of their eukaryotic host. These organelles have their own circular genomic DNA.A team of scientists study a microorganism that lives in a wetland region. The organism is an obligate anaerobe, and it produces energy using the following reaction: CO2+4H4→CH4+2H2OCO2+4H4→CH4+2H2O In which kingdom does this organism most likely belong? A. Fungi B. Protista C. Archaebacteria D. EubacteriaWhich of the following correctly describes the theory of endosymbiosis. Question 9 options: Mitochondria evolved from a genetic mutation within an ancestral prokaryote. An ancestral prokaryote engulfed another prokaryote that eventually evolved into the organelles we recognize as mitochondria and chloroplasts. Some species of prokaryotes can pick up plasmids left behind by other prokaryotes.
