Unit 1: pHIntroduction to Biology and Basic Chemistry
within Biology
pH and Living Systems Lab Guiding Questions
• Why is pH important to biological systems?• How is pH related to water?• How is pH related to ions?• How can the concentration of ions within a solution be
determined by knowing the pH?• Is a slight change in the pH within a living system or
within their environment harmful or significant? WHY or WHY not?
Interdependence
• How does this lab demonstrate the interdependence between organisms (biotic factors)?
• How does this lab demonstrate the interdependence between organisms (biotic factors) and their environment (abiotic factors) ?

Metabolism
• Think about the biochemical processes mentioned in the introduction of the pH and Living Systems Lab. Organisms require and energy and raw materials. Chemical reactions within living systems transform energy and raw materials.
