<u>Answer:</u>
<em>If no other changes occurred emigration would have a negative impact on the population density of a group of organisms.
</em>
<u>Explanation:</u>
<em>Emigration is the movement of a part of population out of an area into a new area. </em>It has a negative impact on the population of the old area and positive impact on the population of the new area.
Population density is the population per unit area that is population per square kilometer.
Thus population density will also be negatively affected by emigration. <em>Hence an area that previously was densely populated might become a sparsely populated area due to emigration. </em>
Answer:
Protostomes: Protostomes may be defined as the organisms in which mouth develops first from the blastopore. These organisms shows the determinate and spiral cleavage. The coelum may be defined as the solid mass of the cell that are derived from the mesoderm.'
Deuterostomes: Deuterostomes may be defined as the organisms in which naus develop first from the blastopore. These organisms show indeterminate cleavage and coelum is derived from the archenteron.
Triploblast : Both protostomes and deuterostomes are triploblastic animals,
None of them is diploblastic in nature.
