Answer:
As the variables are not given, let us help with general explanation on manipulated variable.
Explanation:
A manipulated variable is an independent variable. In a scientific experiment, an independent variable can be described as a variable which can change naturally or which is changed by the researcher to check its effect on the dependent variable. The dependent variable is the variable which is under study and being tested.
For example, to check the difference in photosynthesis rate by light, the amount of light will be the independent variable and the rate of photosynthesis will be the dependent variable.
The correct answer is B. Nasal cavity, larynx, trachea, bronchi, bronchioles, alveoli
Explanation
The breath of living beings is divided into two processes, the first is inhalation and the second is exhalation. Regarding the first, it is the process in which the air is taken by the beings to be conducted to their lungs through their noses, passing through the nasal cavity, larynx, trachea, bronchi, bronchioles and finally alveoli where gas exchange occurs. The second process is the opposite, in which the air inside the lungs converted into CO2 is expelled, passing through the same places in an inverted manner, that is, alveoli, bronchioles, bronchi, trachea, larynx and nasal cavity. So, the correct answer is B. Nasal cavity, larynx, trachea, bronchi, bronchioles, alveoli.
