Answer 1

1.) After looking at the illustration you provided, the internal characteristic that I would expect this animal to have is paired organs. This is because it shows two nephridium and two seminal recepticals. The correct answer is B, paired organs.

2.) Present day animals that belong to the earliest group of primates that evolved include New World Monkeys, which live entirely in trees. I believe this is correct because the New World Monkeys split off and that led to chimpanzees and apes. The correct answer is A.
