Question

living and non living things
a scientist studies an object under a microscope. after careful study, the scientist concludes that the object does not represent a living organism. which of the following would best justify the scientists conclusion?
a. the object cannot move on its own
b. the object shows no signs of reproduction.
c. the object contains no evidence of cells.
d. the object does not appear to be growing or developing.

Explanation:

The cell - theory states that all living organisms are made up of cells. Lack of cells is a definitive sign that an object is non - living. Movement (A) is not a conclusive characteristic as some living things like plants don't move on their own. Reproduction (B) and growth/development (D) are important characteristics of life, but the absence of cells is a more fundamental indicator.

Answer:

C. The object contains no evidence of cells.
