The diagram below shows how hot rock rising up from the Earth's mantle forces its way to the surface to form new sections of oceanic crust at a
mid-ocean ridge. The new crust pushes the older crust away from the
mid-ocean ridge, causing the seafloor to spread. Seafloor spreading
provides evidence for which of the following?
mid-ocean ridge
Lithosphere
Magma
O the law of superposition
the theory of plate tectonics
the theory of natural selection
the law of universal gravitation

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
