11. Why do scientists assume that experimental results can be reproduced? A key assumption in science is that nature behaves in a consistent manner.
12. What did Anton van Leeuwenhoek discover? He discovered a world of tiny moving objects, which he called "animalcules," in rainwater, pond water, and dust.
13. What did John Needham conclude from his test of Redi’s findings? He concluded that the little animals in a bottle of broth could only have come from the juice of the broth.
14. What did Spallanzani do to improve upon Redi’s and Needham’s work? He boiled two containers of broth, assuming that the boiling would kill any microorganisms that were present.
15. How did Pasteur settle the spontaneous generation argument? He designed a special flask to show that as long as broth was protected from microorganisms, it remained free of living things.
Explanation:
It is possible that the error is due to patient’s neck was extended too far.
There are certain rules for the patient positioning during the open-mouth technique. For example, patient’s shoulders should be at equal distances from the image receptor to avoid rotation and the head should be positioned so the skull and the lower margin of the upper incisors are perpendicular (90 degrees) to the image receptor.
