Question 5:
Prebyopia like Hypermetropia is far-sightedness i.e. ability to see far objects but not near objects and can be corrected by using Convex Lens.
Bifocal is used for correcting both visions defects of near-sightedness and far-sightedness.
Question 10:
Pepsin breaks food protein into Peptides which futher are broken into Amino Acids by Trypsin.
