While looking at some seawater through your microscope, you spot the egg of an unknown animal. which of the following tests could you not use to determine whether the developing organism is a protostome or a deuterostome?
a) see whether the ectoderm forms the mature animal's skin/exoskeleton or invaginates to form its gut tissue.
b) see whether the pore formed during gastrulation becomes the mature animal's mouth or its anus.
c) see whether the animal exhibits spiral cleavage or radial cleavage during early development.
d) see whether the coelom is formed from a split in the mesoderm or from mesodermal pockets pinched off the gut.

1. seamount a raised footwall block between normal fault creates this 2. syncline break between rocks where a hanging wall rises relative to a footwall 3. hot spring on rolling hills, this a dip between hills 4. volcanic neck created when a block with hanging walls slips down between normal faults 5. caldera underwater volcano that never reaches above sea level 6. horst natural hot water on earth's surface containing many minerals 7. graben underwater volcano whose top is eroded flat by waves 8. crater less than a mile in diameter; looks like a bowl at the top of a volcano 9. guyot magma that filled the central vent that remains after the volcano has eroded 10. reverse fault over 1 mile in diameter; looks like a bowl over a volcano
