Answer:
A.) The sexual phase can produce variations within the species
Explanation:
Sexual reproduction allows for the mixing of genes which creates variation. Since asexual reproduction just involves one cell, the daughter cells will be identical to the parent. Thus, no variation is created.

Answer:
The correct answer would be - Characteristics can be lost in evolution.
Explanation:
The new evidence helps in developing a new hypothesis. In this case, new evidence proved that the Chondrichthyes diverged after the evolution of bone had started instead of before the evolution started. This process called atavism where an ancestral genetic trait reappears after having lost. This leads to loss of the traits in the evolution
This can take place by knocking the mutation out to overriding the gene by the old gene or overriding the new trait by the old trait during the evolution period.
