Which of the following is true about photoreceptors?

Biology
1 answer:
Naddik [55]2 years ago
5 0

Answer:

a. Rods absorb light throughout the visual spectrum but confer only gray tone vision.

Explanation:

Rods and cones are the two types of photoreceptors present in the eyes. Rods are responsible for night vision or the vision in dim light. Rods do not provide color vision. Therefore, only black, white, and all shades of gray are seen in dim light.  

In complete darkness, full regeneration of cone photopigments is delayed and the eyes are adapted to the darkness first. Rhodopsin is the pigment of rods. It regenerates more slowly and can detect all the colors of the light but does not provide color vision. Therefore, irrespective of the detection of a much dimmer light, threshold flashes appear gray-white only because only the rods are functioning.

Dvinal [7]

Answer:

Although humans and animals (technically “non-human animals”) may look different, at a physiological and anatomical level they are remarkably similar. Animals, from mice to monkeys, have the same organs (heart, lungs, brain etc.) and organ systems (respiratory, cardiovascular, nervous systems etc.)

Humans have a heart with two atria and two ventricles that pushes blood in one direction. Some animals have hearts similar to humans but, other animals have only one atrium and one ventricle or a cardiovascular system that can push blood in two directions.

Memory for stimulus sequences distinguishes humans from other animals. Summary: Humans possess many cognitive abilities not seen in other animals, such as a full-blown language capacity as well as reasoning and planning abilities.
