Which statement applies to cones?

Hearing aids are more beneficial in conductive deafness than in sensorineural deafness.

The image on the retina is upside down and backward due to bending of light rays.

In hyperopia the far source is focused on the retina with accommodation, and the near source is focused behind the retina.

Which of the following structures is associated with pheromonal reception?

Accommodation permits near vision.

Dual innervation of organs by both branches of the autonomic nervous system allows a fine degree of control over these organs.

Which of the following does NOT occur in a photoreceptor during exposure to light?

Which statement applies correctly to polymodal nociceptors?
