Explanation:

The development of dental radiographs has three stages:

The first is to place the radiograph in developer, the second to wash it in water and the third to fix the image and define it with fixative.

The developer is in charge of giving the contrast to the radiographic image and the radiopaque-radiolucent colors, if the radiographic plate lasts less time or the developer is altered due to misuse / maintenance, it will not look correctly and will have a dim image appearance.

<h2>Homologous</h2>

Explanation:

<em>Two or more species share a unique physical feature,</em> for example, an unpredictable bone structure or a body plan, they may all have acquired this component from a typical predecessor.
Physical highlights shared because of developmental history (a typical progenitor) are said to be homologous.
<em>The front flippers of whales and the forelegs of four-legged vertebrates like canines and crocodiles are completely gotten from the equivalent tribal tetrapod structure.</em>
