The part of the curve in shaded area a has a steeper slope than the part of the curve in area b. true each shaded area on the x axis represents a 5 mm hg range in partial pressure of oxygen. true each shaded area on the y axis represents a 10% range in o2 saturation of hemoglobin. false if the partial pressure of oxygen in the blood dropped from 25 to 20 mm hg, the percent o2 saturation of hemoglobin would decrease to about 25%.

what's the question?

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics

the alkaline earth metals (beryllium (be), magnesium (mg), calcium (ca), strontium (sr), barium (ba), and radium (ra)) are a group of chemical elements in the s-block of the periodic table with very similar properties: shiny. silvery-white. hopefully this ? i didn't fully understand the question
