Viruses activity

Why are viruses largely considered to be nonliving?

• Because they dont experience the world like living things do.

• Because they dont display ALL the characteristics associated with living things.

• Because they are really just poisonous rock particles.

• Because they dont undergo sexual reproduction.

There have been hundreds of attempts at defining and redefining what it means to be 'alive' in a biological sense. Which of these options are almost always included, according to the video?

• The ability to reproduce

• the ability to metabolize

• the ability to respond to stimuli

• the ability to evolve and change.

Why do you think the bacteria Wolbachia, which live INSIDE the cells of insects, are considered to be more alive than viruses?

Mitochondria, a feature of many organisms cells, are thought to have evolved from bacteria. They have their own DNA, and a lot of the same machinery that Bacteria have. Why do you think they are not considered alive?

Viruses, Viroids, and Plasmids can insert themselves into your DNA. While they are in your DNA, are they a part of you, and alive? Separate from you and not alive? Why or Why not?

Some scientists think that the infective particle of the virus should be considered only part of a life cycle. They likened the virus to a sperm cell, and the host cell that it combined with was the

• Viroplasm

• Virocell

• Nucleocell

• Viroid Cell

"Replicon" theory says that anything that is capable of reproducing independently should be considered alive. Is this a definition too broad?
