Answer 1

2) pepsin works under acidic medium, whereas trypsin requires an alkaline medium.

3) x is chlorine. It has group number 17 and period number 3

4)hi=120 cm

f= -20

v=-60

1/v + 1/u = 1/f

-1/60 + 1/u = -1/20

1/u = -1/20 +1/60

1/u = -2/60

u = -30 cm

-v/u = hi/ho

60/-30 = 120/ho

ho = -60 cm
