QUESTION 1 While sampling marine plankton in a lab, a student finds a large number of fertlized eggs. The student raises some of the eggs in the laboratory for further study and finds that the blastopore becomes the mouth. The embryo develops into a trochophore larva and coelom. These eggs probably belong to a(n). t eventually has a true gastropod
