The compound eyes of insects function nest in certain conditions because of the
pigments surround each omitidium
While sampling marine plankton in a lab, a student encounters large numbers of fertilized eggs. The student rears 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 eventually has a true coelom. These eggs probably belonged to a(n)

At which developmental stage should one be able to first distinguish a protostome embryo from a deuterostome embryo?
What distinguishes a coelomate animal from a pseudocoelomate animal is that coelomates
have a body cavity completely lined by mesodermal tissue, whereas pseudocoelomates do not.
In sponges, the non-cellular, protein-rich matrix found between the cellular-based choanoderm and pinacoderm is called

radial to bilateral symmetry
You find a baseball-sized sponge on the beach after a storm. You cute a very thin slice and look at it under a microscope. You find mant interconnected canals with chamber about 1 mm in size lined with flagellated cells. The most likely body plan is

What distinguishes complete metamorphosis from incomplete metamorphosis in insects?
radically different appearance between adults and earlier life stages
The only diploid cell of the life cycle of basiomycetes is produced within the basidium by
Turbellarians lack dedicated respiratory and circulatory systems because
none of their cells are far removed from the gastrovascular cavity or from the external environment
The specialized cells that cnidarians use to capture prey are called

Put the lifecycle of the liver fluke Chlonorchis sinesnsis in order
One major difference between ectomycorrhizae and arbuscular mycorrhizae is
ectomycorrhizae do not penetrate plant roots; arbuscular mycorrhizae penetrate plant roots.
