O It provided an explanation as to why prokaryotic cells do not have a nucleus. O It provides an explanation as to why bacteria and mitochondria are similar in size. D It provides an explanation of how life today could have originated from a single cell. D It provides an explanation of how prokaryotic and eukaryotic cells use oxygen to work.. 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 EubacteriaOrigin 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 Nanoarchaeota

Phylogenetic tree of the three domains of life inferred from the highly conserved 16s gene.11:40 Commensalistic relationships are hard to define in relation to prokaryotes because O It can be difficult to determine the benefits derived by the prokaryotes O It can be difficult to determine when one species is benefiting while the other is unaffected O Most prokaryotic relationships with multicellular species are parasitic due to the pathogenic nature of prokaryotes O It can be difficult to prove that the prokaryote is not causing harm to the host speciesAll Archaea and bacteria are microscopic, prokaryotic organisms. However, Archaea and bacteria differ in significant ways. Which of the following is the MOST important reason that Archaea and bacteria belong to separate biological domains? O Archaea do not have a nucleus O Archaea are often resistant antibiotics O Archaea often live in more extreme conditions than bacteria O Archaea are found as single cells or colonies

- What are the flaws ? Prokaryotes can live in many different environments. Anerobic organisms need oxygen to survive, while aerobic organisms can survive without oxygen. Autotrophs are organisms that can assemble high energy macromolecules for their energy. Chemotrophs are organisms that capture energy from light. Extremophiles are organisms that grow in extreme conditions like boiling water. Gram-positive bacteria have few layers of peptidoglycan, while gram-negative bacteria have many layers of peptidoglycan and are surrounded by an outer membrane. Harmful bacteria can cause illness like food poisoning. Helpful bacteria can be used in food production to make yogurt. The endosymbiotic theory states that some of the organelles in eukaryotes were once free living prokaryotes. This is supported by the mitochondria and cytoplasm since they have their own DNA and ribosomes. Harmful protists can cause diseases like malaria in humans and downy mildew in plants. Helpful protists can be…I pis Walden Pond 5: While you were collecting your pond samples, you were troubled by the organism seen below, which was continually biting you: Domain and Kingdom?
