- 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 eukaryotearrow_forwardAfter 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.arrow_forwardOrigin of life BACTERIA EUKARYA ARCHAEA Low-GC Gram-positives High-GC Gram-positives Hyperthermophilic bacteria Origin of- mitochondria Hadobacteria Cyanobacteria Spirochetes Chlamydias Proteobacteria -Origin of chloroplasts All eukaryote phyla Thaumarchaeota Crenarchaeota Korarchaeota Euryarchaeota Nanoarchaeotaarrow_forward

- Which of these characteristics is NOT shared by bacteria and archaea? Group of answer choices presence of plasma membrane absence of membrane-bound organelles presence of peptidoglycan in cell wall absence of a nucleusarrow_forwardPenicillin inhibits bacterial growth by preventing the cross-linking during peptidoglycan synthesis. Why does penicillin not inhibit growth of archaeal cells? Group of answer choices Most archaeal cells have a cell wall, but it is not composed of peptidoglycan. Archaeal cells do not have a cell wall. Penicillin is unable to penetrate the lipid outer membrane that blocks access of penicillin to the peptidogycan crosslinking enzymes. Pencillin is unable to penetrate the S layer to reach the peptidoglycan layer underneath.arrow_forwardWhich of the following do Prokaryotes and Eukaryotes NOT have in common? Select all that apply.
