, What is the scientific method and why is it important? - ANSWERSprocess for
explaining the world that provides an objective approve to conducting experiments to
see if what you believe is true
What does the scientific method limit? - ANSWERSlimits bias
What are the steps of the scientific method? - ANSWERSobservation
hypothesis
experiment
data
conclusion
True or false
results must be replicated many times before a conclusion is accepted - ANSWERStrue
What forms a general theory? - ANSWERSseveral verified hypotheses
What is homeostasis? - ANSWERSmaintenance of a relatively stable internal
environment that is essential for survival and function of all cells and organisms
Sickness and death are consequences of failing to maintain _____________________.
- ANSWERShomeostasis
How do physiological systems act to maintain homeostasis? - ANSWERSHomeostatic
pathway
sensor
integrating center
effector
What is a sensor in the homeostatic pathway? - ANSWERSdetects deviations in a
condition aware form a specified level (set point)
What is an integrating center in the homeostatic pathway? - ANSWERScontrols the
activity of the effector based on input from the sensor to regulate around a set point
What is an effector in the homeostatic pathway? - ANSWERSmakes appropriate
adjustments to counter the change that often operates via a feedback loop
What is feedback? - ANSWERScontrol center sends signals to effectors making fine
adjustments to stay in homeostasis
