If you use more than one independent variable at a time, and will observe a change, you will not know which variable contributed to a changed result.
Kinetic energy is best described as the energy of motion, energy of position, or the energy of electrical change.
Answer:
The Rules of Protein Structure. The function of a protein is determined by its shape. The shape of a protein is determined by its primary structure (sequence of amino acids). The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.
The sequence and number of amino acids is different (each protein has a unique sequence and arrangement of amino acids).
