Grade 10 :: DNA, RNA, and Genetics by MarcBeinder
What is the role of hydrogen bonds in the structure if DNA?
  1. to code for proteins
  2. to synthesize proteins
  3. to separate the strands

Grade 10 :: Evolution by PMISIAS
How can temporal isolation lead to speciation?
  1. If two populations do not like each other, this may lead to the formation of a separate species
  2. If two populations reproduce in different ways, this may lead them to become separate species
  3. If two populations are separated by a geographic barrier, this will cause them to reproduce with other members of their own species which may them to become separate species
  4. If two populations reproduce at different times, they are unlikely to reproduce with each other which may cause them to become separate species
