1 In a person with myopia nearsightedness light from a dista

1. In a person with myopia (nearsightedness), light from a distant object is brought to a focal point.? A) on the retina B) in front of the retina C) behind the retina

2. The three types of cone cells absorb _, , and wavelength of light.
A) red, yellow, blue B) red, yellow, purple
C) red, blue, yellow D) red, blue,green

3. Sound waves pass through this canal on their way toward the eardrum.
A) cochlear duct B) external acoustic meatus
C) semicircular canal D) auditory tube

4. The middle ear .
A) contains the actual organs of hearing (the cochlea) and equilibrium (the vestibular apparatus)
B) conducts sound waves through a canal toward the tympanic membrane
C) carries and amplifies the vibrations of sound waves across three little bones

Solution

1.The correct answer is: B) in front of the retina.

Reason:In myopia,light focusses in front of retina.

2.The correct answer is:D) red , blue ,green

Reason:There are three types of cone cells :red, blue and green that absorb red,blue and green wavelength of light.

3.The correct answer is :B) external acoustic meatus.

Reason:External acoustic meatus is a tube that runs from outer ear to middle ear and passes the sound waves through it,

4.The middle ear is :C) carries and amplifies the vibrations of sound waves across three little bones.

Reason: Vibrations are mainly amplified and carried across the three tiny bones or ossicles named as malleus,incus ,stapes.
