Accepted Answer

### Question 2 (Compare and contrast virus and cell)
# Brief Explanations:
- **Differences**:
  - **Structure**: Cells (prokaryotic/eukaryotic) have a cell membrane, cytoplasm, and genetic material in a defined region (nucleoid/nucleus). Viruses have a protein coat (capsid) and genetic material (DNA/RNA), no cellular structures (no cytoplasm, organelles, or cell membrane).
  - **Reproduction**: Cells reproduce via cell division (binary fission, mitosis/meiosis). Viruses replicate by hijacking host cell machinery to make viral components.
  - **Metabolism**: Cells perform metabolic processes (respiration, protein synthesis). Viruses lack metabolic activity outside a host.
- **Similarities**:
  - Both have genetic material (DNA or RNA) that carries hereditary information.
  - Both can evolve (mutate) over time.
# Answer:
- **Differences**: Cells have cellular structures (membrane, cytoplasm, organelles), reproduce via cell division, and perform metabolism. Viruses have a capsid + genetic material, replicate by hijacking hosts, and no metabolism outside hosts.
- **Similarities**: Both have genetic material (DNA/RNA) and can evolve.

### Question 3 (True/False)
#### Part (a)
# Brief Explanations:
Antibiotics target bacterial structures (e.g., cell walls) or processes. Viruses lack these targets, so antibiotics do not work on viruses.
# Answer:
a. FALSE; Antibiotics target bacteria (e.g., cell wall synthesis), viruses have no bacterial - like structures, so antibiotics can’t treat viral infections.

#### Part (b)
# Brief Explanations:
Viruses are extremely small (e.g., 20 - 400 nm), while host cells (e.g., human cells ~10 - 100 μm) or organisms (e.g., bacteria ~1 - 5 μm) are larger.
# Answer:
b. TRUE

#### Part (c)
# Brief Explanations:
Prokaryotes are cells (e.g., bacteria) with a cell membrane, cytoplasm, and genetic material in a nucleoid. Viruses are not cells (no cellular structure), so they are not prokaryotes (or eukaryotes).
# Answer:
c. FALSE; Viruses are not cells (no cell membrane, cytoplasm, or cellular organization), so they are neither prokaryotes nor eukaryotes.

#### Part (d)
# Brief Explanations:
Viruses can infect all types of hosts: animals, plants, bacteria (bacteriophages), fungi, and protists.
# Answer:
d. FALSE; Viruses infect animals, plants, bacteria (bacteriophages), fungi, etc.—not just animals.

#### Part (e)
# Brief Explanations:
Viruses have no metabolic machinery to replicate on their own. They need to enter a host cell and use the host’s ribosomes, enzymes, and energy to make new viruses.
# Answer:
e. TRUE

### Question 4 (Lytic cycle illustration guidance)
# Brief Explanations:
- **“The virus attaches to the host cell”**: Draw a virus (small, with a capsid) binding to a receptor on the host cell’s membrane. Label the virus, host cell membrane, and receptor.
- **“The virus inserts its genetic material into the host cell”**: Draw the virus at the membrane, with a channel or the capsid releasing the genetic material (e.g., a strand of DNA/RNA) into the host cell’s cytoplasm. Label the viral genetic material, host cell cytoplasm, and the point of entry.
# Answer:
- For “The virus attaches to the host cell”: Sketch a virus (capsid - shaped) adhering to a host cell (round/oval with a membrane) via a receptor - ligand interaction.
- For “The virus inserts its genetic material into the host cell”: Sketch the virus at the host membrane, with the capsid open and genetic material (e.g., a line representing DNA/RNA) entering the host cell’s interior (cytoplasm).
