Question

living and non living things
which evidences below cause scientists to consider viruses as nonliving? choose the two best answer choices.
□ a they contain genetic material in the form of either dna or rna
□ b they do not have a nucleus nor membrane bound organelles
□ c they have no mechanism for reproduction.
□ d outside a living host cell, they have no way to maintain a stable internal environment and cannot move on their own
□ e they do not seek food and obtain energy from food

Explanation:

Living things can reproduce independently, maintain homeostasis, and obtain energy. Viruses lack a self - reproduction mechanism outside a host cell (C), and cannot maintain a stable internal environment or move on their own outside a host (D). Having genetic material (A) is a characteristic of living things, but not sufficient to classify viruses as living. Lack of a nucleus and membrane - bound organelles (B) is not the key determinant for non - living status. Not seeking food and obtaining energy (E) is related to their non - living nature but D and C are more fundamental reasons.

Answer:

C. They have no mechanism for reproduction
D. Outside a living host cell, they have no way to maintain a stable internal environment and cannot move on their own
