I'll work through this biology worksheet step by step.

Let me analyze what's being asked:

Question 1: The table asks to check which characteristics apply to Prokaryotic and Eukaryotic cells for each feature listed.

The features are:
- Can reproduce without host
- Has genetic material
- Membrane-bound organelles
- Cell membrane
- Nucleus

Based on cell biology:

Prokaryotic cells (like bacteria):
- ✓ Can reproduce without host - YES, they can reproduce independently
- ✓ Has genetic material - YES, they have DNA (though not in a nucleus)
- ✗ Membrane-bound organelles - NO, prokaryotes don't have these
- ✓ Cell membrane - YES, all cells have this
- ✗ Nucleus - NO, prokaryotes don't have a nucleus

Eukaryotic cells (like animal/plant cells):
- ✓ Can reproduce without host - YES, they can reproduce independently
- ✓ Has genetic material - YES, they have DNA
- ✓ Membrane-bound organelles - YES, they have mitochondria, ER, etc.
- ✓ Cell membrane - YES, all cells have this
- ✓ Nucleus - YES, eukaryotes have a nucleus

Question 2: Labeling the virus diagram

Looking at the virus structure:
- Label A: Points to the outer protein coat/capsid of the virus
- Label B: Points to the genetic material inside (DNA or RNA)
- Label C: Points to the tail fibers that attach to host cells

For label D, it appears to be pointing to another part of the virus structure, likely the tail sheath or base plate.

Label A is called: Capsid (or protein coat)
Its function: Protects the viral genetic material and helps the virus attach to host cells

Label B is called: Genetic material (DNA or RNA)
Its function: Contains the instructions for making new viruses

Label C is pointing to: Tail fibers
They are important because: They help the virus attach to specific host cells so it can inject its genetic material

Final Answer:

Question 1 Table:

| Characteristic | Prokaryotic | Eukaryotic |
|----------------|-------------|------------|
| Can reproduce without host | ✓ | ✓ |
| Has genetic material | ✓ | ✓ |
| Membrane-bound organelles | ✗ | ✓ |
| Cell membrane | ✓ | ✓ |
| Nucleus | ✗ | ✓ |

Question 2:

Label A is called: Capsid (protein coat)
and its function: To protect the genetic material and help the virus attach to host cells

Label B is called: Genetic material (DNA or RNA)
and its function: Contains instructions for making new viruses

Label C is pointing to: Tail fibers
they are important to attach the virus to host cells
