It takes seven seconds for the pupil to adapt once again to dark conditions after getting exposed to headlight glare.
The pupil of the eye refers to the black circle at the midpoint of the iris. The pupil functions mainly to monitor the amount of light getting inside the eyes, to make sure that to much light does not blanch out the visions in extremely bright light conditions, and to capture as much light as possible in dim light conditions.
Answer:A submitter of a premarket notification submission (510(k)) must demonstrate to the Food and Drug Administration (FDA) that the “new device” is “substantially equivalent” (SE) to a legally marketed predicate device. This guidance is intended to help 510(k) submitters demonstrate substantial equivalence. This guidance does not add new regulatory requirements for submitters, it does not change the 510(k) premarket review standard nor does it create extra or new burdens on what has traditionally been submitted in 510(k)s. FDA developed this guidance to improve the predictability, consistency, and transparency of the 510(k) premarket review process. Furthermore, this document is intended to serve as an aid for evaluating the benefit-risk profile of a new device in comparison to the predicate device.
Answer:

Explanation:
Movement of molecules is very important to maintain a healthy cell environment because some molecules are required by the cell for its growth and development. Some molecules moves inside the cell environment through a semi-permeable membrane such as glucose, oxygen, potassium etc while on the other hand, some molecules are removed from the cell which are waste materials such as carbondioxide etc. If these waste materials are not removed from the cell, it greatly damaged the cell.
