The structures are evidence of evolution in that all living things are homologous with a genetic code which is extremely similar though other genetic code exists and then it suggests a common ancestor.
Human harm is considered homologous structures together with bird’s wings, cat’s legs. A human being has bones for example ulna, fingers, and wrist bones that features appear similar to ones in other animals. Bat’s whales have similar homologous structures which demonstrate that these creatures have a common ancestor.
Answer – C.
One advantage of experiments is
that they allow cause and effect to be considered. The freedom to manipulate variables
in experiments gives researchers the ability to observe and examine various cause
and effect relationships that can be produced by a product, theory, or idea.

There are choices for this question namely:
a. cementation of clastic sediments and precipitates from seawater
<span>b. compaction and recrystallization of volcanic material </span>
<span>c. regional metamorphism of sedimentary and igneous rocks </span>
<span>d. contact metamorphism of unconsolidated gravel
</span>
The correct answer is that the bedrock of the Adirondock mountains is formed mainly by regional metamorphism of sedimentary and igneous rocks. The geology of the Adirondock mountains formed around 5 million years ago with rocks over 1000 million years old. At this very ancient age, the sedimentary and igneous rocks in the Adirondock mountains have undergone extensive heat and pressure hence regional metamorphism of the existing sedimentary and igneous rocks.
