If Archaeans are more closely related to eukaryotes than to bacteria, then which of the following is a reasonable prediction? A) Archaean DNA should have no introns. B) Archaean ribosomes should be larger than typical prokaryotic ribosomes because eukaryotic ribosomes are large. C) Archaeans should lack cell walls because animal cells do not have cell walls. According to the endosymbiotic theory of the origin of eukaryotic cells, how did mitochondria originate? A) from engulfed, originally free-living proteobacteria B) from the nuclear envelope folding outward and forming mitochondrial membranes C) by secondary endosymbiosis Which statement about protists is true? A) Some protists use pseudopods as locomotory structures or as feeding structures. B) Some like foraminiferans and radiolarians have hard shells C) Some like mitochondria, but have compensating bacterial species living symbiotically. D) Some fresh water species arc]e autotrophic. E) All of the above are true. Some green algae (chlorophytcs) exhibit alternation of generations. All land plants exhibit alternation of generations. No charophytes (molecularly linked to plants) exhibit alternation of generations. The correct interpretation of these observations is that A) land plants evolved directly from the green algae that perform alternation of generations. B) plants evolved alternation of generations independently of green algae. C) alternation of generations cannot be beneficial to charophytes.
