The chemical formula for the major component of palm kernel oil is CH3(CH2)14CO2H. The chemical formula for the carbohydrate glucose is C6H12O6. Which statement best describes these macromolecules as foods?
Glucose is a better energy source because it is the only one that can be broken down by living things.
Palm kernel oil would provide a quicker energy source than glucose because it has more carbon atoms that can be used.
Glucose is the only one that would provide energy to living things because it is a key product of respiration.
Palm kernel oil would provide more energy than glucose because it contains more carbon bonds, which release energy when broken.

1.   what is light?

light is an electromagnetic wave visible to the human eye. 

2. what is a reflection?

the rebounding of a light ray when it hits a mirror.

3. what is the incident ray?

contacts the surface of an object.

4. what is the reflected ray?

bounces off a reflective surface.

5. what is the normal ray?

perpendicular to the surface of a mirror.

6. what is the angle of incidence?

an angle formed by the incident ray and the normal.

7. what is the angle of reflection?

an angle formed by the reflected ray and the normal.

8. what is refraction?

(bending.)

9. what is a converging lens?

bring together light rays that pass through.

10. what is a diverging lens?

spreads out light passing through.

11. focal point?

the real point where the refracted rays meet when the incident rays run parallel.
