9. Surtsey is an island located south of Iceland that was formed by a volcanic eruption. Surtsey first
appeared in the 1960s. Ecologists documented the stages of succession as found below
A. Dwarf willow trees begin to grow on the island.
B. Mosses, lichens, and plants that are adapted to be dispersed by the wind or sea and able to grow in
the sand appear on the island.
C. Vascular plants included sea lyme grass and oyster plants appear
D. The lava and sand formation that resulted from the eruption are barren with few nutrients
Write the correct order of the letters A-D above to best represent the order of succession:

Correct Order:

D. The lava and sand formation that resulted from the eruption are barren with few nutrients.

C. Vascular plants included sea lyme grass and oyster plants appear.

B. Mosses, lichens, and plants that are adapted to be dispersed by the wind or sea and able to grow in  the sand appear on the island.

A. Dwarf willow trees begin to grow on the island.

Explanation:

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

the denominator has a very specific role.
