Explain why a protein might not function properly if some of the smaller units that bond to form the protein chain are changed.

Sample Response: Each protein folds in a certain way, and the resulting 3-D

structure of the protein affects its function. If some parts of the protein are

changed, hydrogen bonds may not form in the same place, or the polarity may

change. As a result, the protein will not fold in the same way and the 3-D structure of the protein will not be the same.

Which of the following is true about the speed of light? it depends on the wavelength.

Movement that is like a t a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. transfers energy from one location to another a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
