The amount of tectonic plate movement is measured using Global Positioning System (GPS) satellites and a network of GPS receivers. This technology allows scientists to measure plate movements as small as a few millimeters per year.

Answer from: anastasiasam8996

The Earth's lithosphere is differentiated into small fragments of plates that float on and travel autonomously over the mantle, and the majority of the seismic activity of the Earth takes place at the boundaries of these plates. These plates are known as tectonic plates. In order to determine the movement of plates, scientists can use a combination of satellites and lasers. By focusing lasers on the ground with the help of satellites, the scientists can find the Earth's plates movements, which are as small as a single centimeter per annum.

correct answer is a. and d.

Answer from: Quest

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
