Classify each item as being associated with light positioning (controlling how and where light strikes the retina) or sensory pr
Brilliant_brown [7]

Answer:

- light positioning: c. Extrinsic muscles; d. Pupil

- sensory processing: a. Photoreceptors; b. Occipital cortex; e. Bipolar cells

Explanation:

Extrinsic (extraocular) muscles are muscles that modulate both eye movement and position, whereas intrinsic (intraocular) muscles are muscles that focus the eye and control how much light enters into the eye. The pupil is the black center of the eye within the iris through which light passes before being focused onto the retina. Photoreceptors are specialized neurons located in the retina that respond to light, converting it into electrical signals that can stimulate biological processes. Photoreceptors in the retina are divided into two categories 1-rods (responsible for vision at low light levels), and 2-cones (active at higher light). Bipolar cells are neurons that transmit signals from the photoreceptors to the ganglion cells, thereby processing light signals received from rods and cones. The occipital cortex is a brain region that represents the visual processing center and contains most of the anatomical region of the visual cortex.

A victim with a foreign-body airway obstruction becomes unresponsive. what is your first course of action
Mrrafil [7]
The answer to this question would be: start doing CPR.

If the victim becomes unresponsive, probably the foreign body completely obstructs the airway and the oxygen level is already too low. Without the victim help, taking out the foreign body will be hard.
In this case, CPR will be the best option since the pressure from chest might push the foreign body away and the CPR can help circulate the blood.
