The pharynx forms the food substance into balls and then pushes it into the a. mouth b. small intestine c. esophagus d. stomach

c.) polymerase chain reaction

age range would be the answer

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
