What type of photoreceptor cell allows us to see gray tones in dim light, and provides our peripheral vision

Rods.

Explanation:

There are two types of photoreceptor cells, the cones, and the rods.

The cones adapt our vision to bright light and allow us to see colors. On the other hand, rods photoreceptors make us see in the dark and do not perceive many colors; that is why we can not distinguish colors in the dark. Also, they provide peripheral vision since they are on the external edges of the retina.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.
