Sample Item Grade 10 TAKS Booklet 4 According to the graph, what partial pressure of oxygen would saturate 67% of hemoglobin in the blood? A B C D 2.8 kPa 5.2 kPa 8.7 kPa 12.4 kPa
Bio/IPC (2)(C) This item demonstrates that students will need to be proficient with reading a graph to collect information. This is just one way the student expectation can be tested.
Sample Item Grade 11 TAKS Booklet 1 The graph shows the increase in a Stentor population. If this trend continues, what will be the approximate size of the Stentor population after 4 weeks? A B C D 325 per 100 mL 348 per 100 mL 401 per 100 mL 454 per 100 mL
Bio (2)(C) This item requires students to recognize a Pattern in data and then make a prediction based on that pattern. Although an answer can be obtained by drawing the curve freehand, an accurate answer can best be obtained by using the changes in slope to predict where the last data point would be found.

Grade 11 April 2004 (5 of 5) 53 The table shows the number of bubbles released by an elodea plant per minute at different light intensities. The rate of bubble release is representative of the photosynthetic rate. Which statement is supported by these data? A The rate of photosynthesis is slowest when elodea produces 7 to 12 bubbles. B Lower light intensity causes a higher photosynthetic rate. C The greatest difference in photosynthetic rate is between the 75 W and 100 W light bulbs. D Light intensity has little effect on the rate of photosynthesis of elodea
