Answer:
At the "Elongation" or "middle stage" of the translation, the peptide bond is formed.
Explanation:
We know that there are three steps or stages of the translation process. Among these 3, in the elongation stage, amino acids are carried to the ribosome by tRNAs, and then they become linked together to form a chain.
In this stage, at first, methionine-carrying tRNA starts in the middle slot of the ribosome, called the P site. Next to it, a new codon is opened in another slot, called the A site. The A site will be used for the "landing site" for the next tRNA. Once the matching tRNA has arrived in the A site, the formation of the peptide bond happens. This peptide bond connects one amino acid to another. This step transfers the methionine from the first tRNA onto the amino acid of the second tRNA in the A site.

Answer: D. The olivine became the crust and the Iron melting defended the earth to become the core.
Explanation:
Earth was formed after it has went through a molten stage that led to the heavy materials sure as Iron metal moving inward to form the core, and the light materials moves toward the surface to form the crust.
The heat for the melting came from meteorite impacts which is usually very hot, the moon's impact, and the decay of radioactive elements.
Geological activity on the earth is driven from this initial source of heat at the earth's formation until now.
