ANS: These organisms are most likely part of domain Archaea and kingdom Archaebacteria. Bacteria in this group include organisms that live in extreme environments, such as the ones around hot springs. The trait that positively identifies them as Archaea is that there is no peptidoglycan in their cell walls. PTS: 1 DIF: Bloom s Level E 130. ANS: Both are viral reproductive cycles. In a lytic cycle, the virus causes the destruction of the host cell. In the lysogenic cycle, the viral DNA becomes integrated into the host cell's chromosome after which it is passed on to future generations of the host cell. PTS: 1 DIF: Bloom s Level B 131. ANS: Viruses are not living things. PTS: 1 DIF: Bloom s Level C 132. ANS: Penicillin interferes with the enzyme that links the sugar chains in the bacterial cell wall. Because neither viruses nor animal cells have cell walls, penicillin has no effect on them. PTS: 1 DIF: Challenge 133. ANS: 1. A virus injects its DNA into a bacterium. 2. The viral nucleic acid becomes part of the host chromosome. 3. The viral nucleic acid is inactive but is replicated when the host cell chromosome replicates. PTS: 1 DIF: Bloom s Level C 134. ANS: In the lytic cycle, a virus attaches to a host cell, it injects its nucleic acid into the cell. The host s metabolic machinery makes viral nucleic acid and proteins, and then new virus particles are assembled. The host cell bursts and releases new virus particles. PTS: 1 DIF: Bloom s Level C NAT: LS_4a 7
135. ANS: In the lysogenic cycle, viral nucleic acid enters a host cell and remains dormant. However, the viral nucleic acid replicates along with the host cell s DNA. The viral nucleic acid becomes active and separates from the host cell s genetic material, takes over its function, and reproduces more viruses. The host cell is destroyed as new viruses are released. PTS: 1 DIF: Bloom s Level C NAT: LS_4a 136. ANS: Both plants and green algae have cell walls that contain cellulose. Both groups have the same types of chlorophyll used in photosynthesis. Algae and plants store food in the form of starch; other organisms store food as glycogen and other sugars.
