Arthropods invaded land about 100 million years before vertebrates did so. This most clearly implies that

#Unit 9. Diversity of Life Forms
  1. arthropods have had more time to co-evolve with land plants than have vertebrates.
  2. extant terrestrial arthropods are better adapted to terrestrial life than are extant terrestrial vertebrates.
  3. ancestral arthropods must have been poorly adapted to aquatic life, thus experienced a selective pressure to invade land.
  4. vertebrates evolved from arthropods.

N2 combines with hydrogen to form ammonia under elevated temperature (about 200°C) and high pressure (about 200 atmospheres) and in the presence of a metal catalyst (usually iron). The extreme conditions are required to overcome the high activation energy of the reaction. This nitrogen fixation reaction, called
