Answer:
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.
Where air pollution is not especially severe, predators have much more impact on leaf-beetle populations than parasites do
The pH scale is from 1-14 and if the water is on 7, it would make it a neutral substance (C).
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
