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.

Explanation:
Two genetically identical daughter nuclei.
The true statement about the relationship between true moss sporophytes and gametophytes is: (d) Sporophytes are parasites of gametophytes.
Sporophyte is the part of the life cycle in plants where the plants are asexual and in diploid phase of their life. The plants produce spores during this stage. In vascular plants sporophyte is the dominant stage of life.
Parasites are the organisms that live inside or outside an organism and depend upon that organism for their food as well. Apart from extracting food, the parasites also provide some kind of harm to the host they live in. Sporophytes are called parasites because they directly developed from the fertilized egg in archegonia.
The given question is incomplete, the complete question is:
Considering that the mature sporophytes of true mosses get their nutrition from the gametophytes on which they grow, and considering these generations as individual plants, what is true of the relationship between true moss sporophytes and gametophytes?
a. Sporophytes are endosymbionts of gametophytes.
b. Sporophytes are mutualists of gametophytes.
c. Sporophytes are commensalist of gametophytes.
d. Sporophytes are parasites of gametophytes.
