The answer would be: <u>Molten material that cooled quickly.</u>
Igneous rocks are formed by the cooling of molten material. So we can cross out the last two choices. The rock has no identifiable crystals so it is most likely an Extrusive igneous rock. They form on the surface where they cool quickly.
Those that form underground are called intrusive rocks. They cool slowly allowing enough time for crystal formation.
He was the first to provide an explanation of evolution supported by evidence.
The first step of protein synthesis is called transcription. The DNA transcription to mRNA is actually the first step of the protein synthesis. During the transcription step the instructions encoded in the DNA of the genes are transcribed into the nucleotide sequence code of a ribonucleic acid (RNA)....
so your answer is Option (A)
A genes dna is transferred to a molecule called an rna in the cell nucleus. Then the Rna assembles the protein and continues until the ribosomes "stop".
Answer:
the process which includes as growth, differentiation, respiration, digestion, and excretion during their life time is life process.
