Correct answer: B. Their envelope is not sensitive to sunlight

  • A. They survive for a short time
  • B. Their envelope is not sensitive to sunlight
  • C. They are tolerant to antibodies
  • D. Envelope is derived from host

Explanation

Enveloped virus is a virus that has an outer wrapping or envelope. This envelope comes from the infected cell, or host, in a process called "budding off." During the budding process, newly formed virus particles become "enveloped" or wrapped in an outer coat that is made from a small piece of the cell's plasma membrane.

About Viruses

Viruses are acellular infectious particles made of genetic material enclosed by a protein capsid, sometimes with a lipid envelope. Their replication depends on a host cell and may follow lytic or lysogenic cycles, so viral structure and reproduction differ fundamentally from those of cellular organisms such as bacteria.
