- Evolutionary microbiologists developed a theory about a common ancestor for all eukaryotic cells. Below is a model of the theorized changes during the origin of eukaryotic cells. Prokaryotes are not capable of phagocytosis, or engulfing outside particles by creating a pocket in the cell membrane. Which of the following changes in early prokaryotes could be predicted to result in the emergence of eukaryotic organisms? A - the development of genetic transfer mechanisms in prokaryotes B - the evolution of predatory or parasitic relationships in prokaryotes C - the emergence of collections of cells functioning together in prokaryotes D = the expansion of internal structures to support larger individual cells in prokaryotesarrow_forwardmake a drawing of a phylogenetic tree that contains all 3 domains of life. The tree should include at least three different animals, two plants, chemoheterotrophic bacteria, photoautotrophic bacteria, chemoheterotrophic archaea, thermophilic archaea and fungi. Identify both primary endosymbiosis events on the tree and draw a line to connect it to the organism that would become the future organelle.arrow_forwardBased on genes from mitochordrial DNA the most accepted tree of life includes three domains.

- The theory of the endosymbiotic origin of mitochondria and chloroplasts was first proposed by the biologist Lynn Which of the following statements provides support for the theory of endosymbiosis? 1. All the genes found in chloroplasts are homologous to genes found in the nucleus of eukaryotic cell. 2. Mitochondria contain their own ribosomes. 3. Proteins need a targeting sequence to be imported into a chloroplast. 4. Mitochondria can generate a proton gradient and harness it to synthesize ATP. O A. 1, 2 and 3 B. 1 and 3 C. 2 and 4 D. 4 only E. All of 1, 2, 3 and 4 are correct.arrow_forwardExplain why the answer is correct. For eukaryote cells to evolve into new types of eukaryotic organisms, which of the following would one expect to occur? The correct answer is E a) these cells have evolved because they have different DNA because of mutations b) Their endoplasmic reticulum is synthesizing new and/or different proteins. c) These specialized cells activate new genes to synthesize new proteins. d) these organisms have new characteristics because they have acquired new genes. e) all of these are truearrow_forwardUnder the endosymbiotic theory for the origin of the eukaryotic cell. The ancestor of mitochondria and chloroplasts original became part of mutualism with a larger host cell. Which of the following best explains this mutualism? A) The mitochondria and chloroplasts provided specialized reproduction as part of the proto-germ line while the larger host cell provided energy for growth and reproduction. B) The mitochondria and chloroplasts provided gene products that could be used by the larger host cell for improved parasitization. C) The mitochondria and chloroplasts provided molecular energy in return for protection by the larger host cell. D) The mitochondria and chloroplasts produce toxins that the larger cell utilized to defend itself from other cells mutually increasing the defense of all those involved.arrow_forward
