Answer:
Rate and depth.
Explanation:
Breathing may be defined as the process of intake of oxygen and exhalation of carbon dioxide. The inhalation and exhalation depends on the partial pressure of gases, atmosphere and pressure of alveoli.
The breathing rate can be changed easily by increasing or decreasing the time of inspiration and the expiration. This changes the volume of oxygen and carbon dioxide in the body. The depth of breathing is controlled by the respiratory center present in the brain. The stimulation of the accessory muscles may increase the thoracic volume change and alters the breathing depth.
Thus, the answer is rate and depth.

Answer:
B
Explanation:
Chemoreception is a physiological process where an organism reacts to a chemical stimulus in their environment.
Pheremones are chemical substances that organisms release into their environments as a form of communication.
Pheremones bind to chemoreceptors which causes a response once the nervous system of the bee has analyzed and identified the chemical substance. The bee can then react with further communication.
