Question

multiple-choice question
why might the characteristics of life change?
because scientist were wrong
because chemistry changes
because scientist are making new discoveries

Explanation:

Scientists' understanding of the characteristics of life evolves as they make new discoveries (e.g., new organisms or biological phenomena). The first option is incorrect as scientists revise understanding based on evidence, not being "wrong" in a simplistic way. Chemistry changing isn't the primary reason for changes in life's characteristics.

Answer:

C. Because scientist are making new discoveries (assuming the third option is labeled C; if the options are A, B, C with A: Because scientist were wrong, B: Because chemistry changes, C: Because scientist are making new discoveries, then the answer is C. Because scientist are making new discoveries)
