Question

If an object on mars appeared to move and react to stimuli what other characteristics would make it live?

Answer 1

move how? react how?

Answer 2

self replication

Answer 3

Characteristics of living things:

Homeostasis

Organization (made of at least one cell)

Metabolism

Growth

Adaptation

Response to stimuli

Reproduction

Answer 4

There are a lot of basic definitions of life:

* It must be able to reproduce

* Movement

* Energy conversion

* Growth

I think there are a couple more I can't think of. An object must have all of these characteristics to be alive. The absence of one indicates it is not alive. For example a rabbit reproduces, it moves, it converts food into energy and it grows. Therefor it is alive.

In comparison, just because a solar panel converts energy doesn't mean its alive because it deosn't reproduce or anything.

Answer 5

oxygen and water
