- Which of the following explains why protists are considered a paraphyletic group? A Protists are prokaryotic. B Protists cannot be a monophyletic group because their morphology and behavior are so variable. C Protists lack a common ancestor. O D The MRCA of the protists also gave rise to plants, animals, and fungi. O E Choices B and D are both correct.arrow_forwardOscillatoria is a thread-shaped Cyanobacteria, while Spirogyra is a thread-shaped Protist. Make a table the difference!arrow_forwardCompare the phylogenetic tree of protists with the secondary endosymbiosis theory which proposes how photosynthetic protists evolved. Are both reconcilable? Explain.arrow_forward
- A parasitic protist has been isolated and is on a microscope slide. How could you determine whether it belongs to te Apicomplexans or Excavata supergroup? Look for spores which would indicate Excavata Look for flagella which would indicate Excavata There is no way to distinguish based on structural characteristics. Look for flagella which would indicate Apicomplexansarrow_forwardIf you were to create an evolutionary tree in which amoebas were included within the kingdom of organisms to which they were the most closely related (rather than with protists, where they are currently placed), where would you put them?arrow_forwardwhy is the kingdom protista not a valid group from an evolutionary perspective?arrow_forward
