Question

viruses - bacteriophages label this diagram of a bacteriophage, choosing from words in the box below. sheath collar nucleic acid spikes tail fiber capsid baseplate

Explanation:

To label the bacteriophage diagram, we identify each structure:

• The purple hexagonal part enclosing the twisted structure is the Capsid (holds nucleic acid). The twisted structure inside is Nucleic acid.
• The ring below the capsid is the Collar. The cylindrical part below the collar is the Sheath.
• The circular structure at the bottom of the sheath is the Baseplate, with projections called Spikes. The thread - like structures from the baseplate are Tail fibers.

From left (top to bottom) and right (top to bottom):

1. Left top: Nucleic acid (inside capsid)
2. Left second: Capsid (hexagonal outer part)
3. Left third: Collar (ring below capsid)
4. Left bottom: Sheath (cylindrical part)
5. Right top: Capsid (hexagonal outer part, alternative view)
6. Right second: Sheath (cylindrical part, alternative view)
7. Right third: Baseplate (circular at bottom of sheath)
8. Right bottom: Tail fiber (thread - like from baseplate)

(Note: The exact labeling may depend on the diagram's specific orientation, but the key is matching the structure names to their visual representations. The words from the box are used to identify each part: Nucleic acid (inside capsid), Capsid (hexagonal shell), Collar (ring below capsid), Sheath (tail tube), Baseplate (bottom of tail), Spikes (projections on baseplate), Tail fiber (fibers from baseplate).)

Answer:

Left (top to bottom): Nucleic acid, Capsid, Collar, Sheath; Right (top to bottom): Capsid, Sheath, Baseplate, Tail fiber (adjust based on precise diagram alignment, but using the terms: Nucleic acid, Capsid, Collar, Sheath, Capsid, Sheath, Baseplate, Tail fiber (with Spikes on baseplate and Tail fibers as the long threads))
