1. Why are viruses considered nonliving but bacteria are considered living? Give two reasons. (1 point)
mezya [45]

Answer:the virus simply can't replicate. Viruses fail the second question for the same reason. ... Finally, a virus isn't considered living because it doesn't need to consume energy to survive, nor is it able to regulate its own temperature.Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.

Explanation:

Viruses, like bacteria, are microscopic and cause human diseases. ... Viruses also lack the properties of living things: They have no energy metabolism, they do not grow, they produce no waste products, and they do not respond to stimuli. They also don't reproduce independently but must replicate by invading living cells.
