- Which of the following periods is the earliest during which animals may have appeared? a. Ordovician period b. Cambrian period c. Ediacaran period d. Cryogenian periodarrow_forwardWhich of the following is an accurate point that supports the idea that the earliest protocells relied first on RNA (not DNA) as inherited information? A. RNA is composed of lipids, and lipids were present on early Earth before the nucleotides that compose DNA were B. RNA is a monomer (unlike DNA), so it is simpler and more likely to have been used by these simple protocells C. DNA would have been too large to fit into the small protocells, but RNA was small enough to fit D. RNA can serve dual roles as both genetic information storage and an enzyme (but DNA cannot do both) ..arrow_forwardFossils found in deeper layers of the Earth generally have ____ 14C than fossils found in the upper layers. a. more c. the same amount of b. less d. different types ofarrow_forward
