- Considering which organelles were created through the endosymbiotic theory, which of the following is NOT something that the host could receive from the engulfing a symbiont? A. the engulfed cell provided the host cell with adenosine triphosphate (ATP) B. the host cell was able to survive anaerobic conditions with the engulfed cell alive C. the engulfed cell provided the host cell with carbon dioxide D. the engulfed cell allowed the host cell to metabolize glucoseMitochondria are thought to be the descendants of certain alpha proteobacteria. They are, however, no longer able to lead independent lives because most genes originally present in their genome have moved to the nuclear genome. Which phenomenon accounts for the movement of these genes? Group of answer choices A. recombination B. conjugation C. translation D. endosymbiosisWhich is a piece of evidence that supports the endosymbiotic theory? Select all that apply. (Group of answer choices) A. many bacteria are resistant to antibiotics B. eukaryotic cells have cell membranes C. mitochondria have their own DNA D. chloroplast DNA is more similar to cyanobacteria DNA than eukaryotic DNA E. ribosomes are present in eukaryotic cells F. mitochondria must divide to multiply, cells can't build them

The endosymbiont hypothesis state that prokaryotes evolved into eukaryotic cells 2. Eukaryotes contain organelles such as mitochondria and chloroplast 3. Organisms develop by a process known as spontaneous generation 4. Bacteria is an example of prokaryoric cwll 5. Prokaryote is a type of cell that has no nucleus and no cell membrane but has cytoplasm
