Which 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)

Since 1735, the Linnaean classification system has been the basic system for all taxonomy in biology. Which statement best explains the reason for changing how organisms are classified today?
A. Organisms are evolving at a faster rate than in the past
B. More diverse and complex organisms are being discovered
C.  There are more organisms today than there were in the past
D. New information about the genetics of species is being discovered
