Question
If Archaean are more closely related to 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 ribosomes are large. C) Archaean should lack cell ribosomes animal cells, how did According to the endosymbiotic of the origin of cells, how did originate? A) from originally free-living B) from the nuclear envelope folding outward and forming C) by secondary endosymbiosis Which statements about protons is true? A) Some proteins use B) some like have hard shells C) Some but have compensating bacterial species living symbiotically. E) All of the above are true. Some green algae (chlorophytes) exhibit of generations. All land plans exhibit alternation of generations. No generations. The connect interpretation of these observations is that A) land plants evolved directly from the green algae that perform B) plants evolved alternation of generations independently of C) alternation of generations cannot be beneficial to charophytes Which of the following was not a challenge for survival of the land plants? A) sources of water B) sperm transfer C) D) animal predation E) absorbing enough light If all fungi in an environment that perform decomposition were to suddenly go then which group of organisms should benefit most, due to the fact that their competitors have been removed? A) plants B) protists C) is to xylem as is to phloem. A) Vascular cambium: cork cambium B) Vessel element; sieve-tube member C) Cortex: pith Which statement about plants is false? A) Seedless vascular plants have microscopic gametophytes. B) Modern gymnosperms and modem angiosperms have pollen that can be transported by wind. C) Modern gymnosperms and angiosperms both have microscopic gametophytes You are given an organism to identify. It has a fruiting body that contains many structures with eight haploid spores lined up in a row. What kind of a fungus is this? A) zygomycete B) ascomycete C)Explanation / Answer
55. B) Archaean ribosomes must be larger than common prokaryotic ibosoms becouse prokaryotic ribosoms are larg.
