–Answer The study of the functions, properties, and behaviors of cells, including their physical and chemical characteristics.
–Answer maintaining a stable environment despite changes through differ- ent mechanism (MULTIPLE factors)
–Answer mechanism that brings everything back to set point and maintains stability ex. regulating body temp and blood sugar levels
–Answer mechanism that amplifies the effects of a change instead of reversing it.ex. blood clotting and releasing oxytocin during childbirth which stimulates muscle contractions and make childbirth quicker

–Answer process where organisms adjust to ONLY ONE factor through temporary physiological changes.ex. sweating 1 / 2
