Nearly all changes to Earth suppressed the formation of life. Changes to the climate, oceans, land, and atmosphere had little effect on multicellular organisms because they were so diverse. Enviromental changes produced new niches and opportunities for adaptation. Correct! Correct! There is no evidence that changes to the environment contributed to evolution. 1 / 1 pts Question 2 What is the current scientific understanding of how life originated on Earth? Life appeared on Earth brought here from a different solar system. Early cells were extracted from igneous rock. Biomolecules were put together following a blueprint until a cell formed. Living systems formed by lawful self-assembly. Correct! Correct! 1 / 1 pts Question 3 What does "eukaryote" mean?
C. Complex, multicellular organisms D. Both B and C Correct! Correct! A. Simple, single-celled organisms B. Complex, single-celled organisms 1 / 1 pts Question 4 What evidence do scientists have that biomolecules (such as amino acids) can self-assemble? Scientists have no evidence; it is an untested hypothesis. Scientists have demonstrated in the lab that biomolecules can self- assemble under conditions like those on early Earth. Correct! Correct! Amino acids are encoded in self-assembling DNA regions. Scientists have put amino acids together, following blueprints. 1 / 1 pts Question 5 What is the current scientific understanding of how biomolecules appeared on Earth? Biomolecules formed by lawful self-assembly. Correct! Correct! Amino acids were brought here from a different solar system. Early amino acids and biomolecules were extracted from igneous rock.
