Decrease a person ability to hear because pinnae funnel sound into the ear canal and if its enlarge example swollen, the tunnel will be more narrower for sound to pass
C. Decrease a person’s ability to hear because pinnae funnel sound into the ear canal
Explanation:
In mammmals, especially humans, the pinna also known as auricle is a large fleshy cartilage outer structure of the hear which is situated on the lateral aspect of the head. The pinna direct sound waves toward the auditory canal. Although the pinna may direct sound into the auditory canal but this portion of the ear is not vital for hearing.
The only main importance of the auricle is just to capture sound, the most important aspect of the outer ear is the ear canal itself, if the ear canal is not open, hearing will be dampened.

When a plant cell is placed in a solution with a lower water potential it will lose water osmotically and plasmolyze.
During the process of osmosis water moves from a region of higher water potential to a region of lower water potential.
<u>Loss of water by the plant cells makes it to shrink or reduce in size and consequently, the plasma membrane pulls away from the cell wall, producing plasmolysis.</u>
