Answer: A. True.

Explanation:

The AIDS virus may constantly change it's form in the host body by mutating. The body immune system becomes unable to produce antibodies which can fight against these mutated cells.

Also, the vaccination used for the purpose of immunization will not be able to combat will the causative agent in the body of the host. As the vaccine contains the microbe which can fight against the virus present in the body. But as the virus is changing it's form the microbe may not be able to compete with the virus. Hence, the use of vaccine will become useless.

3) Orthoptics is a specialty affiliated with the eyecare profession that main focus is on strabism (wandering eye)

4) Electroretinography (ERG) is an eye test that measures retinal activity

5) Aphakia is the loss of the eye's lens due to surgical intervention

6) Cornea - front part of the eye

2) Tympanometry - Tympanometry is a test that is used to assess the state of the middle ear and eardrum mobility which is called tympanic membrane and conductive bones by generating changes in the ear canal's air pressure.

3) Orthoptic - Orthoptics is a specialty affiliated with the eyecare profession that main focus is on strabism (wandering eye), amblyopia (lazy eye) and eye movement disorders treatment and non-surgical management.

4) Electroretinography -  Electroretinography (ERG) is an eye test that measures retinal activity (the part of the eye that detects light).

5) Aphakia  -  Aphakia is the loss of the eye's lens due to surgical intervention, such as a perforating wound or ulcer, or congenital defect in cataract surgery.

6 ) Cornea - The part cornea is the clear front of the eye containing the iris, pupil and anterior chamber.
