It seems like you've accidentally combined multiple questions into one. Let's break them down:

1. "Why are viruses considered to be non-living?" Viruses are considered non-living because they cannot replicate by themselves. They need a host cell to reproduce. They are also too small to be seen under a light microscope, but this is not the reason they are considered non-living. Viruses do contain proteins and genetic material.

2. "Which of the following structures are never found in viruses?" Viruses do not have a nucleus or a cell membrane. They do have a protein coat and genetic material.

3. "What is the name for this life cycle?" The life cycle where viruses infect a host cell, replicate their DNA and protein coats, and then cause the host cell to burst is called the lytic cycle.

4. "Which of the following statements about the lysogenic life cycle is not true?" The statement that is not true is "It is associated with the symptoms of infection". In the lysogenic cycle, the virus integrates its DNA into the host's DNA and does not cause symptoms. The virus can later enter the lytic cycle, which does cause symptoms, in response to certain triggers.
