The endosymbiont theory offers an explanation for how eukaryotic cells could have obtained mitochondria and chloroplasts through a symbiotic relationship with prokaryotic cells that changed over time. What structural feature of prokaryotic cells might you expect to have changed before any endosymbionts could be acquired by eukaryotic cells?

Classify each statement as to whether it represents a piece of evidence that supports the endosymbiont theory of the evolution of mitochondria and chloroplasts from prokaryotes. Some organellar genes have migrated to the nucleus. Evidence for the endosymbiont theory Does not support endosymbiont theory Some organelle proteins are encoded in the nucleus. Organelles do not have flagella. Mitochondrial rRNA genes are most similar to the rRNA gene of a bacterium. Organelle translation is inhibited by antibiotics that inhibit prokaryotic translation...

What is mutualistic symbiosis? How does mutualistic symbiosis relate to the endosymbiont theory? Which 2 organelles could be the result of endosymbiosis? What specific evidence is used to show how these organelles could have once been independent prokaryotic cells?

1. Explain the distinction between the cytosol and the cytoplasm of a cell? Tell whether lysosomes, mitochondria, ribosomes and DNA are part of the cytosol or the cytoplasm or both. Do bacteria have a cytosol or a cytoplasm? 2. Describe the Endosymbiotic Theory and list the evidence that supports it. 3. Explain why ribosomes cannot be visualized with a light microscope but can be easily detected with an electron microscope. 4. Describe the chemistry of carbon atoms. Tell about their...

1. Consider the thrifty phenotype hypothesis of health disparities. a. Briefly explain what this theory suggests and some of the evidence supporting this theory. b. Use the four key graphs in Grossman model to illustrate how the thrifty phenotype hypothesis can explain socioeconomic disparities in health (draw or create the graphs). For each graph, include a brief written explanation. c. Suppose you are a policymaker charged with reducing health disparities. If you believe the thrifty phenotype hypothesis is the root...
