Question

name these structures:
a. ____________________
b. ____________________
name these processes:

1. ____________________
2. ____________________
3. ____________________
4. ____________________

Explanation:

• A: The structure labeled A is a host cell. Viruses (like bacteriophages) attach to and infect host cells.
• B: The structure labeled B is a virus (specifically a bacteriophage, as indicated by its shape which is typical for viruses that infect bacteria).
• 1: The process of a virus attaching to a host cell is called adsorption.
• 2: Once attached, the virus injects its genetic material into the host cell. This is the injection process.
• 3: Inside the host cell, the viral genetic material takes over the host's machinery to replicate viral components. This is the synthesis and assembly process.
• 4: Newly formed viruses are released from the host cell. This is the release process (often by lysis of the host cell in the case of bacteriophages).

Answer:

A. Host cell
B. Virus (Bacteriophage)

1. Adsorption
2. Injection
3. Synthesis and Assembly
4. Release
