Which phrases describe non-foliated rocks? Check all that apply.

a. have grains in parallel layers
b. have randomly arranged grains
c. include quartzite and marble
d. tend to split along their bands
e. form from crystallized magma

The correct answer is option b.

Explanation:

The rocks present deep underneath the crust of the Earth, which get transformed by the effect of chemical procedures, pressure, and temperature are known as metamorphic rocks. One of the kinds of metamorphic rocks is the non-foliated rocks that get produced by the igneous interventions.  

The minerals present within the non-foliated rocks get produced by the process of crystallization, these rocks possess atoms, which are held very close to each other, and the outside composition of the rocks do not possess any form of layering or band. Hence, one can say that these rocks possess grains that are arranged randomly. Some of the examples are quartzite, marble, etc.  

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
