To determine the two essential components that all viruses have, we need to consider the basic structure of a virus.

1. Nuclear membrane: This is present in eukaryotic cells but is not a component of viruses.
2. Envelope: Some viruses have an envelope, but it is not essential for all viruses. Non-enveloped viruses exist as well.
3. Inner core with nucleic acid: This is a fundamental component of all viruses. They must contain genetic material (either DNA or RNA).
4. Outer capsid: All viruses possess a capsid, which is the protein shell that encases and protects the viral nucleic acid.

Final Answer

The two essential components that all viruses have are:

• Inner core with nucleic acid
• Outer capsid
