Which statement supports this graph?

• The enzyme's activity increases with time

• The enzyme functions best at a specific temperature

• The enzyme works best when multiple enzymes are present

• The enzyme works well in humans especially in the blood cells

A scientist collected data of various concentrations of radon. The scientist concluded that radon was found two seasons the year. Based on the graph, which statement defends the scientists' conclusion

• Radon concentrations were found throughout the summer and winter

• There were no concentrations of radon found throughout the year

• Winter and summer radon concentrations decreased the same in each location

• None of the statements defend the scientists' conclusion

If I need to examine the whole body of a butterfly, which microscope would I use?

• Transmission electron microscope

• Scanning electron microscope

• Compound/Light microscope

• Dissecting microscope

What piece of evidence is found on this graph?

• Higher temperatures work well with this enzyme

• The enzyme activity is directly influenced by the temperature

• The enzyme only functions at 5 degrees Celsius

• The enzyme only functions at 62 degrees Celsius

Which description is represented by this graph

• The product decreases and then increases over time

• The product increases then decreases over time

• The product remains stable over time

• The product increases and then becomes stable over time

What is a valid conclusion about the enzyme activity?

• pH changes the role of their function in the immune system

• Each enzyme has a specific pH that it operates at its best

• Enzymes do not work at a pH higher 9

• pH has no effect on enzyme activity
