Which of the following is the correct order for types of radiation from lowest to highest frequency?
microwaves → radio waves → visible light |
|
infrared waves → microwaves → ultraviolet light |
|
visible light → ultraviolet light → radio waves |
|
radio waves → visible light → gamma rays |
The electromagnetic spectrum covers all possible wavelengths and frequencies of radiation. From lowest frequency (longest wavelength) to highest frequency (shortest wavelength) radiation: radio waves → microwaves → infrared waves → visible light → ultraviolet light → X-rays → gamma rays.
In the pancreas, lipase converts fat to:
glycerol and fatty acids |
|
complex carbohydrates |
|
amino acids |
|
simple sugars |
The acids produced by the pancreas contain several enzymes that aid in digestion. Lipase converts fat to glycerol and fatty acids. Pancreatic amylase breaks down complex carbohydrates into simple sugars. Trypsin converts polypeptides (the building blocks of protein) into amino acids.
