In your own words, describe the evidence that supports these explanations. (Minimum of 2 complete sentences.)The endosymbiotic hypothesis for the origin of chloroplasts from gram-negative prokaryotes is supported by all of the following lines of evidence except: the presence of enzymes for the light-dependent and the dark reactions of photosynthesis the presence of circular DNA resembling that of photosynthetic eubacteria the presence of mRNA, tRNA, and rRNA similar to that of the cyanobacteria their use of mitosis rather than binary fission during cell division the presence of 70s ribosomes, consisting of 30s and 50s ribosomal subunits

(a) Describe the coevolutionary pattern that systematists look for (b) Name the evolutionary mechanism that causes the phylogeny of hosts to be similar to the phylogeny of their symbionts. (c) Name 2 phenomena that cause a phylogeny of hosts and a phylogeny of their symbionts to come to differ. (d) Some tapeworm groups found in modern marine mammals evolved long before their hosts. Describe how the phenomenon of mass extinctions explains this.In the pictures below, identify the arrowed reproductive structures of microscopic cyanobacteria based on the following descriptions: Akinetes are dormant structures larger than the vegetative cells, are rich in food reserves, and have thick walls. Most filamentous cyanobacteria develop akinetes in adverse conditions (e.g., winter, dry periods). When favorable conditions return, they germinate and produce new filaments. Hormogonia are short pieces of filaments consisting of 5–15 trichomes that fragment and develop into new filaments. Heterocytes (or heterocysts) are multicellular structures that have a thick and massive sheath, formed by members of the Nostocales. It is the location of the enzyme nitrogenase for nitrogen fixation, the conversion of nitrogen gas into ammonium and then amino acids. They may be intercalary or terminal in position and may germinate from either end or both the ends to give rise to new filaments. Non-filamentous cyanobacteria generally produce spores…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.

Thank you.In the early 1930s, G. F. Gause carried out a series of experiments using two species of ciliated protists (Paramecium), which are single-celled eukaryotic protozoans. The protists were cultured together and separately, with the bacteria being the single food source. The results are shown in the figure below. (a) Based on figure, identify and explain the interaction that is taking place between P. caudatum and P. aurelia. (b) Clam shrimp, a natural predator to P. caudatum, is introduced to the culture containing both P. caudatum and P. aurelia after 24 days. Predict the impact that the clam shrimp will have on the culture and the populations. Justify your prediction.
