Calculate the quantity (in mmol) of protons that will be released when 2.80 mmol of oxygen bind to deoxyhemoglobin at ph 7.4 and the ph then returns to 7.4, i. e. in going from point a to point b on the curve. step 1: calculate the [hhb]/[hb] ratio at ph 7.4. step 2: calculate the mmol of hhb in 2.80 mmol of deoxyhemoglobin at ph 7.4. step 3: calculate the [hhbo2]/[hbo2] ratio at ph 7.4. step 4: calculate the mmol of hhbo2 in 2.80 mmol of oxyhemoglobin at ph 7.4. step 5: calculate the protons released as the difference between nhhb and nhhbo2.

Air pressure is measured in pascals. for a professional american football game, the ball should be inflated to about 90,000 pascals. scientists studied the effects of air temperature on the pressure inside american footballs by taking these steps: 1. prepare 100 footballs. 2. measure each football's air pressure. 3. divide footballs into 10 groups. 4. place the groups in different lockers cooled to different air temperatures. 5. after 12 hours, remove the footballs from lockers. 6. measure each football's pressure again. 7. compare the new pressures to the starting pressures. what two terms best describe the variable "air pressure inside the football" in this experiment? independent, qualitative independent, quantitative dependent, qualitative dependent, quantitative
