The table shows data about the percentages of gases in air inhaled and exhaled. The gases are oxygen (O2), nitrogen (N2), and carbon dioxide (CO2). Which of these conclusions can be made from the data in the table?
A. Cellular respiration produces nitrogen
B. Cellular respiration uses oxygen
C. Cellular respiration produces carbon dioxide
D. Photosynthesis produces oxygen
B. Cellular respiration uses oxygen
B. Cellular respiration uses oxygen and C. Cellular respiration produces carbon dioxide
Yes, both B. Cellular respiration uses oxygen and C. Cellular respiration produces carbon dioxide can be concluded from the data in the table. The percentage of oxygen in inhaled air is higher than in exhaled air, indicating that oxygen is being used during cellular respiration. The percentage of carbon dioxide in exhaled air is higher than in inhaled air, indicating that carbon dioxide is being produced during cellular respiration.
To determine which of these conclusions can be made from the data in the table, you would need to provide the table or data. Please provide more information so that I can assist you further.
To determine which conclusions can be made from the data in the table, we need to analyze the percentages of gases inhaled and exhaled.
First, let's identify the gases in question:
- Oxygen (O2): Essential for respiration and used by cells.
- Nitrogen (N2): An inert gas that makes up a significant portion of the air we breathe.
- Carbon dioxide (CO2): A waste product of cellular respiration.
Now, let's compare the percentages of these gases inhaled and exhaled based on the data in the table:
Inhaled (%) Exhaled (%)
- Oxygen: 21 16
- Nitrogen: 78 78
- Carbon dioxide: 0.04 4
From this data, we can draw the following conclusions:
A. We cannot conclude that cellular respiration produces nitrogen since the percentage of inhaled and exhaled nitrogen remains the same (78%).
B. We can conclude that cellular respiration uses oxygen. The percentage of inhaled oxygen is higher (21%) than the exhaled percentage (16%), indicating that oxygen is being utilized by the body's cells during respiration.
C. We can conclude that cellular respiration produces carbon dioxide. The percentage of inhaled carbon dioxide is very low (0.04%) compared to the exhaled percentage (4%), suggesting that carbon dioxide is a waste product produced during cellular respiration.
D. The table does not provide information about photosynthesis. So, we cannot conclude that photosynthesis produces oxygen from the given data.
Therefore, based on the data in the table, the correct conclusion is B. Cellular respiration uses oxygen, and C. Cellular respiration produces carbon dioxide.
