2. In a forest, a storm knocks down a tree exposing
part of the ground to sunlight. What changes could
result from the external factor of sunlight in that
area?
A. Fewer plants will grow near the ground, resulting in
fewer biotic resources for animals near the ground.
B. Tall trees will grow thicker, providing food and
shelter for tree-dwellers.
C. Plants near the ground will grow faster, providing
more biotic resources for animals near the ground.
D. No changes will occur.

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails. b. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. c. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails have other functions, because prokaryotes don't have nuclei.
