Answer 1

When the girl opens her eyes in a brightly lit room, her pupils will shrink (constrict). This occurs because the bright light triggers the photoreceptors in her eyes, which sends signals to the muscles around the iris. These muscles then contract to reduce the size of the pupils, allowing less light to enter the eye and helping to protect the retina from excessive brightness. This reflexive response is part of the pupillary light reflex mechanism.
