How are forams useful for researchers to study changes in ocean temperature over time? What are mixotrophs? What is endosymbiosis and why is it consider to be the source of eukaryotic diversity? Why are we confident this only happens once? What is primary and secondary endosymbiosis? Was there another endosymbiotic event that led to a third lineage? What group of organisms possesses a structure that might suggest this possibility and what is the structure? Why is the structure question different from the ancestor of other plastids? What are diatom blooms and why are they of particular interest to climate change scientists?
Why do some biologists describe the mitochondria of diplomonads and parabasalids as “highly reduced”?
Carotenoids in algae have evolved through primary and secondary endosymbiosis. provide a well-constructed phylogenetic tree to show where carotene, neoxanthin, zeaxanthin, violaxanthin, fucoxanthin, and lutein arose in the macrophytic, multicellular groups of algae. add descriptive and informative title to it
