Question

Quizplus · Accepted Answer

Silicon is chemically similar to carbon, which is the basis of all known life on Earth. While silicon-based life has not been discovered, the similarity in chemical properties suggests that it may be possible. The other choices are not scientifically supported reasons for the possibility of silicon-based life. Silicon is chemically similar to carbon, which is the fundamental element for all known life on Earth. This similarity suggests that silicon could potentially be used as a basis for life as well.
