1. The passage is most probably directed at which kind of audience?
State legislators deciding about funding levels for a state-funded biological laboratory
Scientists specializing in molecular genetics
Readers of an alumni newsletter published by the college that Paul Gross attended
Marine biologists studying the processes that give rise to new species
Undergraduate biology majors in a molecular biology course
2. It can be inferred from the passage that the morphogenetic determinants present in the early embryo are
located in the nucleus of the embryo cells
evenly distributed unless the embryo is not developing normally
inactive until the embryo cells become irreversibly committed to their final function
identical to those that were already present in the unfertilized egg
present in larger quantities than is necessary for the development of a single individual
3. The main topic of the passage is
the early development of embryos of lower marine organisms
the main contribution of modern embryology to molecular biology
the role of molecular biology in disproving older theories of embryonic development
