[OU.01] The diagram below shows two electromagnetic waves. Two electromagnetic waves shown side by side. Wave 1 (on the left) shows a very low frequency. Wave 2 (on the right) shows a high frequency. Both waves demonstrate the same amplitude.

Which of these statements best describes the use of the two waves?

Wave 1 is used to image people's bones and Wave 2 is used to transmit cellular phone signals.
Wave 1 is used to destroy cancerous cells and Wave 2 is used to transmit cellular phone signals.
Wave 1 is used to transmit cellular phone signals and Wave 2 is used to destroy cancerous cells.
Wave 1 is used to destroy cancerous cells and Wave 2 is used to detect the location of objects that emit heat.

Match the descriptions / definitions with the term they best describe 1. three dimensional relationship of the different polypeptide chains in a multisubunit protein or protein complex 2. common folding pattern in proteins in which a linear sequence of amino acids folds into a right-handed coil stabilized by internal hydrogen-bonding between polypeptide backbone atoms. 3. the amino acid sequence of a protein 4. a region on the surface of a protein that can interact with another molecule through noncovalent bonding. 5. three-dimensional arrangement of alpha-helices and beta-sheets within a single polypeptide, typically stabilized by a variety of noncovalent bonds, including ionic and hydrogen bonds, and nonpolar interactions / hydrophobic force. 6. the chain of repeating carbon and nitrogen atoms, linked by peptide bonds, in a protein. 7. common structural motif in proteins in which different sections of the polypeptide chain run alongside each other and are joined together by hydrogen bonding between atoms of the polypeptide backbone. 8. portion of a polypeptide chain that has a discrete tertiary structure of its own and can often fold independently of the rest of the chain 9. regular local folding patterns in a protein, including alpha-helix and beta-sheet a. primary structure b. beta-sheet c. protein d. coiled-coil e. polypeptide backbone f. secondary structure g. side chain h. tertiary structure i. binding site j. alpha-helix k. quaternary structure l. protein domain
