they appear in embryonic development.
Mesoderm, Blastula, Zygote, Gastrula

What is the difference
between a coelom and a
pseudocoelom?
A coelom is a true body cavity that only
makes contact with mesoderm.
General for 600
Predict the result if an 8-cell arthropod
embryo splits into two 4-cell embryos.
Both parts would die. Because arthropods are
protostomes, the fate of each cell at the eight-cell
stage has already been determined, so the two
half-embryos cannot each form whole new
embryos.
Invertebrates for 200
A parasite has two different host species during its
life cycle. How does one determine which host is
the primary host?
The primary host is the one in which sexual
reproduction (specifically fertilization) takes place.
