More than 90% on the crust is composed of silicate minerals. Most abundant silicates are feldspars<span> (</span>plagioclase<span> (39%) and alkali feldspar (12%)). Other common silicate minerals are </span>quartz<span> (12%) </span>pyroxenes<span> (11%), </span>amphiboles<span> (5%), micas (5%), and clay minerals (5%).</span>
Explanation:
New ocean crust is formed at the mid ocean ridges. The new crust is then pushed away from the ridge as newer crust comes to the surface. The ocean crust then spreads out enlarging the ocean. The farer away from the ridge the ocean crust is the older the crust
A box full of feathers and the same size box full of rocks. They occupy the same volume but have a different mass.
(A 1 meter by 1 meter by 1 meter cube box full of feathers.

Answer:
Option C, 3′-GTCAAGCCT-5′
Explanation:
The template used for replication synthesizes amino acids with
a) reverse head and tail ends - which means the 5' end will pair up up with the 3' end of the amino acid synthesized by the given template like wise 3' will pair up up with the 5' end of the synthesized amino acid.
b) The pairing of template occurs as per the rule of base pair in which
adenine (A) pair up with thymine (T) and guanine (G) pair up with cytosine(C).
Thus given template 5'-CAGTTCGGA-3' will
synthesise 3′-GTCAAGCCT-5′
Hence, option C is correct
