Based on the graph, which of the following is a function of the respiratory system?
A.
to deliver oxygen to cells for cellular respiration at different rates so that different amounts of energy can be made when needed
B.
to detect changes in the outside world through nerve impulses and send these impulses throughout the body
C.
to increase the breathing rate during heavy activity so that more carbon dioxide can be absorbed by respiratory cells
D.
to decrease a person's heartbeat during heavy activity and decrease the flow of blood to areas that will pool with blood
C. to increase the breathing rate during heavy activity so that more carbon dioxide can be absorbed by respiratory cells
Jeremy buys a value pack of cheese crackers that contains 42 1/2
ounces of crackers. He divides this into servings of 1 1/4
ounces each. What is the total number of servings Jeremy can make from the value pack?
To find the total number of servings Jeremy can make from the value pack, we need to divide the total number of ounces in the value pack by the number of ounces per serving.
The value pack contains 42 1/2 ounces of crackers, which is equal to 42 + 1/2 = 42.5 ounces.
Each serving is 1 1/4 ounces.
To divide 42.5 ounces by 1.25 ounces per serving:
42.5 / 1.25 = 34
Therefore, Jeremy can make a total of 34 servings from the value pack of cheese crackers.
Based on the given options, the function of the respiratory system that best matches is option C.
C. to increase the breathing rate during heavy activity so that more carbon dioxide can be absorbed by respiratory cells.
The respiratory system is responsible for exchanging gases with the environment, and during heavy activity, an increase in breathing rate helps to supply more oxygen to the cells and remove additional carbon dioxide produced during increased cellular respiration.
To determine the correct answer, we need to understand the function of the respiratory system and analyze the information provided in the given options.
The respiratory system is responsible for the exchange of oxygen and carbon dioxide between the body and the external environment. It allows oxygen to enter the body and be delivered to cells for cellular respiration, where energy is produced. It also removes carbon dioxide, a waste product of cellular respiration, from the body.
Let's analyze each option in light of this information:
A. "To deliver oxygen to cells for cellular respiration at different rates so that different amounts of energy can be made when needed" - This statement accurately describes one of the primary functions of the respiratory system, which is to deliver oxygen to cells for cellular respiration at different rates depending on the body's energy needs. This option aligns with the function of the respiratory system and is a potential correct answer.
B. "To detect changes in the outside world through nerve impulses and send these impulses throughout the body" - This statement does not accurately describe the function of the respiratory system. The respiratory system is primarily involved in gas exchange and is not responsible for detecting changes in the outside world or sending nerve impulses throughout the body. Therefore, B is incorrect.
C. "To increase the breathing rate during heavy activity so that more carbon dioxide can be absorbed by respiratory cells" - This statement accurately describes another function of the respiratory system. During heavy activity, the body's demand for oxygen increases and the breathing rate increases to deliver more oxygen and remove excess carbon dioxide. This option aligns with the function of the respiratory system and is a potential correct answer.
D. "To decrease a person's heartbeat during heavy activity and decrease the flow of blood to areas that will pool with blood" - This statement does not accurately describe the function of the respiratory system. The respiratory system is primarily involved in gas exchange and does not directly control the heartbeat or blood flow. Therefore, D is incorrect.
Based on the above analysis, we can conclude that options A and C are functions of the respiratory system. However, to determine the correct answer, we would need more context or additional information.
