To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(5) + 32\)
\(F° = {45 \over 5} + 32\)
\(F° = 9 + 32 = 41\)
During digestion, after proteins are broken down where does the undigested food go next?
stomach |
|
large intestine |
|

Food is mixed with gastric acid and pepsin in the stomach to help break down protein.
Which of the following is the correct order for types of radiation from lowest to highest frequency?
infrared waves → microwaves → ultraviolet light |
|
visible light → ultraviolet light → radio waves |
|
microwaves → radio waves → visible light |
|
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.
The respiratory and circulatory systems are similar in that they:
transport nutrients |
|
add carbon dioxide |
|
transport oxygen |
|
deoxygenate blood |
Like the respiratory system, the circulatory system serves to transport oxygen throughout the body while removing carbon dioxide. In addition, the circulatory system transports nutrients from the digestive system.
