question 13 (2.5 points)
the seed plants became dominant during the late _ when the climate became _.
cambrian; wetter
carboniferous; drier
carboniferous; wetter
cretaceous; drier
cretaceous; wetter

Explanation:

During the late Carboniferous period, the climate became drier. Seed plants, which are better adapted to drier conditions compared to some other plant types (like many non - seed plants that rely more on moist environments for reproduction), became dominant. The Cambrian is too early for seed plants to be dominant. The Cretaceous is a later period when angiosperms (a type of seed plant) further diversified, but the key transition to seed - plant dominance in terms of the described climate change (drier) occurred in the Carboniferous.

Answer:

Carboniferous; drier
