8.
Which of the following is not an adaptation that contributes to the success of flowering plants?
A)The dominance of the haploid stage allows development of complex structures.
B)The evolution of pollen allows transfer of sperm from plant to plant without the need of water.
C)The evolution of the seed to protect the embryo and to nourish the young plant.

9.
How does internal fertilization make reproduction more efficient?
