Step by step
Solved in 2 steps
- Which of the following are lines of evidence for endosymbiosis? Inner membranes are similar to plasma membranes of prokaryotes O DNA structure in chloroplasts and mitochondria are similar to that of prokaryotes Mitochondrial ribosomes are more similar to prokaryotic than eukaryotic ribosomes O The DNA found in the nucleus of a eukaryotic cell is very similar to that of prokaryotes.An endosymbiont is any organism that lives within the body or cells of another organism. Each would have performed mutually benefiting functions from their symbirie relationship. Why are the mitochondria considered an endosybiont in an eukaryotic cell ? They have two membranes have DNA sequences that indicate origin from the alpha- prroteobacteria has a means for using oxygen and create ATP can break down glucose for energy O They contain hydrolytic enzymesWhich 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 eukaryote
- Which 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.According to Lynn Margulis's theory of endosymbiosis, bacteria entered large cells either as parasites or as undigested prey as illustrated. All the following are proof that mitochondria and chloroplast evolved from bacteria, except: Endosymbiosis in a nutshell: 1. Start with two 2. One bacterium engulfs the other. 3. One bacterium now lives inside the other. independent bacteria. 4. Both bacteria benefit from the arrangement. 5. The internal bacteria are passed on from generation to generation. O a they each have a double membrane they have chromosomes similar in shape to their host they are the size of bacteria their DNA is different from its hostWhich of the following is not true concerning the mitochondria and chloroplasts and is not evidence in support of the Endosymbiotic Theory? Both divide independently of the eukaryotic cell they are within Both contain their own DNA in a single, circular chromosome Both can survive independently when removed from a eukaryotic cell Both are about the same size as a bacteria
- What types of biological abilities can be combined to create more capable, more complex cells? How does the presecence of different types of ribosomes inside a eukaryotic cell strengthen the endosymbiotic theory? How does chloroplasts and mitochondria found within a cell have two membranes? How does the emergence of endosymbotic theory change the way humans view microorganisms? Will people be comfortable imaginning that the life functions of pants and animals, including their own, are actually dependent on the coexistence of many different microscopic pieces?How does the emergence of endosymbiotic theory change the way humans view microorganisms? Will people be comfortable imagining that the life functions of plants and animals, including their own, are actually dependent on the coexistence of many different microscopic pieces? This question is not answered yetAn infectious disease research group is studying a microbe that can cause infections and gastrointestinal disease in humans, and which can also survive and reproduce in hamsters. A dormant cyst form of the microbe infects human hosts through fecal-oral transmission if they come in contact with hamster droppings and don’t wash their hands before eating. The organism exhibits active, motile morphological forms at other stages of its life cycle. Sexual reproduction (fusion of haploid gametes) occurs in the hamsters; only asexual reproduction occurs in humans. It has a nucleus, but does NOT have a cell wall. This microbe could be which of the following? Protozoan Fungus Bacterium Virus
- Select all of the following that provide evidence about the support to the Theory of Endosymbiosis. U U U Chloroplasts and mitochondria have their own DNA Chloroplasts and mitochondria are present in prokaryotic bacteria Chloroplasts and mitochondria are enclosed in a double membrane Chloroplasts and mitochondria divide by a process that closely resembles binary fission The DNA of chloroplasts and mitochondria is very similar to that of other free-living prokaryotesAfter the glacial retreat at the end of the last ice age, some three-spine stickleback fish (Gasterosteus aculeatus) were isolated in small lakes. A mutation occurred in these fish that resulted in the loss of pelvic spines. Today, all freshwater sticklebacks lack pelvic spines, but are still classified as members of the same species as marine sticklebacks. Scientists collected sticklebacks from both marine and freshwater environments and placed them together in a controlled environment. Which of the following statements describes the effect of the mutation on their ability to interbreed? They should be able to interbreed and produce fertile offspring. They will not be able to interbreed and produce offspring because of hybrid breakdown. They will not be able to interbreed and produce offspring because of mechanical isolation. They should be able to interbreed and produce offspring, but the offspring may experience reduced hybrid fertility.Which of the following statements supports the endosymbiosis theory (select all that apply) Mitochondria are often referred to as the powerhouse of the cell. Mitochondria and chloroplasts have their own ribosomes. The mitochondrial and chloroplast genomes are circular. Mitochondria and chloroplasts have double membranes. Mitochondria and chloroplasts have their own DNA.
