Which photoreceptor cells are primarily responsible for allowing you to read a newspaper in a dimly lit room?
a. the blue-sensitive cone cells in the retina
b. the green sensate cone cells in the retina
c. the blue- and green-sensitive cone cells in the retina
d. the rod cells in the retina

The correct answer is: D) the rod cells in the retina.

Explanation:

Rod cells are one of the two types of photoreceptor cells and are located in the retina of the eye (concentrated at its outer edges). These rod cells are used for peripheral and night vision. These photoreceptors are much more sensitive to light than cones, but they do not perceive color and details as well as these other cells.

liquid crystals are matters in a state which have properties between those of conventional liquids and those of solid crystals[1]. liquid crystal is partially ordered and anisotropic. in terms of molecular order, liquid crystal molecules have one-dimensional or two-dimensional long - range order.
