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.
The control would be how much fertilizer you put in. This would be the control because if you put more fertilizer in one plant than the other, the thing helping the plant grow may not be what type of fertilizer but how much fertilizer. <span />
Vestigial organs have long been one of the classic arguments used as evidence
for evolution. The argument goes like this: living organisms, including man,
contain organs that were once functional in our evolutionary past, but that
are now useless or have reduced function. This is considered by many to be compelling
evidence for evolution. More importantly, vestigial organs are considered by
some evolutionists to be evidence against creation because they reason a perfect
Creator would not make useless organs.
I just know this much about vestigial organs, maybe I helped you:))
