What is a eukaryote in terms of how genetic information (DNA) is stored and cellular structures, especially those using filaments and tubules? 2. What evidence is there that mitochondria and chloroplasts have an endosymbiotic origin? 3. Look at the Eukaryote phylogeny in the text. Back in the day, you would have been taught that there were five kingdoms; Animals, (land) Plants, Fungi, Monera (Archaea and Eubacteria) and Protists – the single celled Eukaryotes. What kind of phylogenetic group would Protists be?

Explanation:

Coenocytic is a multinucleate cell which results from multiple nuclear divisions without cytokinesis,with multiple independently dividing nuclei

Mitochondria and chloroplasts are believed to have developed from symbiotic bacteria, specifically alpha-proteobacteria and cyanobacteria respectively

Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms; at some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion

Mixotrophic protists are single celled eukaryotes that can obtain carbon and energy from more than one trophic process (e.g. photosynthesis and phagocytosis)

The ability of protists to combine photosynthetic and heterotrophic nutrition in a single cell is well known

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
