Solution Steps

Step 1: Identify the Data in the Infographic's Graph

The infographic's graph is a pie chart showing the elements in the human body as a percentage of total mass. The elements and their percentages are:

  • Oxygen: 65%
  • Carbon: 18%
  • Hydrogen: 10%
  • Nitrogen: 3%
  • Other elements (including Ca, P, K, S, Na, Cl): 4%
Step 2: Analyze the Bar Graphs

There are three bar graphs below the pie chart. We need to determine which of these bar graphs present the same data as the pie chart.

Step 3: Compare Each Bar Graph to the Pie Chart
  • The first bar graph shows the elements in the human body with the same percentages as the pie chart: Oxygen (65%), Carbon (18%), Hydrogen (10%), Nitrogen (3%), and Other elements (4%).
  • The second bar graph shows the big four elements (Oxygen, Carbon, Hydrogen, Nitrogen) as 96% and other elements as 4%. This does not match the pie chart exactly.
  • The third bar graph shows a single bar for elements in the human body, which does not provide the same detailed breakdown as the pie chart.

Final Answer

The first bar graph presents the same data as the infographic's pie chart, thus allowing the same conclusions to be drawn.
