Which of the following is not an example of a reflex action? a. quickly withdrawing your hand after touching a hot pan b. passing food through your digestive tract c. blinking your eye when a splinter gets into it

"B.passing food through your digestive tract.
The movement of food through the digestive tract is caused not by a reflex but by peristalsis. Peristalsis is the process by which a series of radially symmetrical contractions and relaxations occur anteriorly along the digestive tract, called peristaltic waves."

The answer to this will be from your lab notes/procedure. it would be best to ask another student who participated in the lab as we do not know what was done, what enzyme or if the temperature is celsius or fahrenheit. if i were to guess though i'd say the rate stopped due to enzyme denturing at high temperature
