After a volcanic eruption, lava flowed over an area and then cooled to form a thick layer of new rock. One thousand years later, a thriving forest with diverse flora and fauna is found in that area, even though evidence suggests that several large forest fires have occurred. Which statement best describes what happened?

A.) Secondary succession occurred, followed by several primary successions.
B.) Only secondary successions occurred.
C.) Primary succession occurred, followed by several secondary successions.
D.) Only primary successions occurred

C. Primary succession occurred, followed by several secondary successions.

Explanation:

Primary succession only occurs from bare rock and soil (caused by the volcano eruption in this case). When plant life suffered from forests fires, life was still left behind to continue growth, so these would be considered secondary successions.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

gold i'm pretty sure i might be wrong
