Answer:
the Hawthorne effect
Explanation:
In conducting an experiment on prison violence, researchers randomly placed cameras in certain cells. The results showed unusually low incidents of conflict between prisoners in areas where cameras were present. This change in the prisoners' behavior as a result of being observed is known as the Hawthorne effect.
The Hawthorne Effect is the tendency for people who are the subjects of an experimental study to make positive adjustment to their behavior that is being evaluated only because it is being studied and not because of changes in the experiment parameters or stimulus.
In this case the prisoners adjusted their behavior because of the presence of cameras not for any other reason.
The crown of the tooth is covered by<u> the enamel</u>, the hardest substance in the body.
The hardest material in the human body is dental enamel, or the hard tissue that covers the outside of the tooth crown.
It is more mineralized and durable than bone and the most heavily mineralized bodily tissue.
Calcium phosphate, a hard mineral, makes up the majority of it.
Dentin is the layer that lies behind your enamel. It is created from mineral-secreting live cells. The pulp, the primary living component of the tooth, is located underneath the dentin.
Dental crowns are caps that are affixed to broken teeth.
When fillings are ineffective, crowns are utilized to preserve, cover, and restore the contour of your teeth.
Metals, porcelain, resin, and ceramics can all be used to create dental crowns.
