The correct Answer is:
To answer the question "An envelope surrounds the virus in", we need to analyze the viruses mentioned: HIV, TMW, T2, and Lambda phage. ### Step-by-Step Solution: 1. **Identify the Viruses**: The question lists four viruses: HIV, TMW, T2, and Lambda phage. 2. **Understanding HIV**: - HIV (Human Immunodeficiency Virus) is known to have an envelope. This envelope is derived from the host cell membrane and surrounds the viral capsid. - The envelope contains proteins that are crucial for the virus to enter host cells. 3. **Understanding TMW, T2, and Lambda Phage**: - TMW (Tobacco Mosaic Virus), T2, and Lambda phage are types of bacteriophages. - These viruses do not have an envelope; they consist of a protein coat (capsid) that encases their genetic material. 4. **Conclusion**: Based on the characteristics of these viruses, we can conclude that the only virus among the options that has an envelope surrounding it is HIV. 5. **Final Answer**: Therefore, the answer to the question is that an envelope surrounds the virus in **HIV**.
