Pupils dilate and constrict in order to allow an adequate amount of light to pass through the retina. Both great or small amount of light will damage retina and vision. For example, if eyes are exposed to eyes suddenly, and pupils do not constrict, a great amount of light will pass to the retina and the vision will be damaged. Similarly, if there is no enough light and pupil do not dilate, a small amount of light will pass to the retina and, again, the vision will be damaged.

Part I

In extension to measuring the amount of light that enters the eye, the pupillary light reflex presents a helpful diagnostic tool. It provides for examining the uprightness of the sensory and motor functions of the eye. if your pupils didn't shut suddenly when abruptly disclosed to light, you'll get a tremendous shot of light (simultaneously with UV rays and other possibly dangerous rays) to your retina, which can severely mess up your vision.

Part II

Without it, we would go blind. If there is not sufficient light and the pupils do not dilate, a small number of light will pass to the retina and the image will be damaged.

can you predict the properties of a compound by knowing the properties of the elements that make up the compound?
MakcuM [25]
No, you cannot determine the properties of a chemical compound by solely knowing the properties of the elements that make up the compound, because in a chemical compound, the properties are completely different and or independent of the chemical and or physical properties of the individual elements used to make up the compound.

-Dominant- [34]

Science must be open and aim for the common good. Scientific advancement is done to provide well-being to the population and to facilitate the way in which this population lives, moves, communicates and reinvents itself. As the population is constantly changing, it is necessary that scientific thinking be open to these changes as well.

Social changes, climate change, behavioral and food changes shape current scientific thinking. The advancement of technology is possible, thanks to the human being's ability to change. We can use several examples that prove the need for scientific thinking to be open to change. Among these examples are the changes in the media, the change in scientific thinking about how the human being should communicate has promoted a breakthrough in the technology that has resulted in smartphones, applications and computers that have so much changed the way we communicate.

Another example is the methods of treating diseases, each time disease becomes stronger, more difficult to treat and more common, scientific thinking has to change to formulate treatments more effective and less devastating.
