Which type of metamorphic rock has randomly arranged grains and does not split into layers?
foliated
banded
massive
non-foliated

The correct option is D. Non-Foliated

Explanation:

Metamorphic rocks can be described as thee rocks which are buried deep inside the Earth and due to the extreme conditions deep inside the Earth, the original texture, colour and composition of these rocks has been changed.

Metamorphic rocks contain two basic types:

1. Foliated

These kinds of rock are layered due to the immense heat and pressure present inside the Earth's crust.

2.Non- foliated:

These rocks are not layered.

The correct answer is -  Base pairing rule and DNA.

Explanation:

According to the base pair rule during transcription, along with antisense strand DNA, the RNA was made and the bases of the purines and pyrimidines strands bind together, Uracil paired with the A-strand and the C strand being paired to G-strand in transcription within the nucleus.

Thus, the correct answer in the first line is "Base-pairing rule" while in the second line is "DNA".
