  A patient presents with conductive hearing loss following a middle ear infection. Imaging reveals restricted movement of the small bones connecting the tympanic membrane to the inner ear.

A patient requires a corneal transplant following severe damage to the eye. The ophthalmologist explains that corneal transplants are among the most successful types of organ transplants. Which of the following characteristics MOST contributes to the high success rate of corneal transplants? A. The cornea has no blood vessels, reducing immune system exposure to donor antigensB. The cornea contains high levels of regenerative stem cells that rapidly replace donor tissueC. The cornea is surrounded by a thick capsule that prevents immune cell entryD. The cornea is primarily composed of cartilage, which is poorly recognized by immune cellsE. All of the above  

   A patient closes their eyes and is asked to raise one arm.
