A
Explanation:
The genome of prokaryotes has no introns hence their mRNA does not need splicing like in eukaryotic cells. Also, because the genome of prokaryotes is not delimited from the cytoplasm by a nuclear membrane, ribosomes can attach to the elongating mRNA during transcription and begin translation. Therefore translation of mRNA occurs concurrently with transcription which cannot happen with eukaryotic cells.
In the nucleus of eukaryotic cells, transcription results to a nascent mRNA which is spliced into a mature mRNA.The mature mRNA has to travel outside the nucleus to the cytoplasm to be translated by ribosomes.

Answer: C). Extraction
Explanation:
Minerals are the inorganic susbtances obtain from the under surface of the earth crust. They are collectively found in the geosphere of earth.
The mineral formation is a long geomorphic process it does not involve any biological activity. After mineral formation mineral extraction is the next step in the resource cycle.
The extraction process involves mining techniques.
Answer:Polymerization, any process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer. The monomer molecules may be all alike, or they may represent two, three, or more different compounds.
