Question

1. what is one expected change in the eye as people age?

the lens is less flexible.
the pupil reacts slower.
vessels grow.
fluid increases.

Explanation:

As people age, the lens of the eye loses its flexibility. This is a common and well - known age - related change in the eye. The pupil's reaction time may also slow down slightly with age, but the loss of lens flexibility (presbyopia) is a more prominent and expected change. Vessel growth is not a typical expected change in the normal aging eye in the absence of disease. Fluid increase is also not a normal expected change in the aging eye.

Answer:

The lens is less flexible.
