Q2. Apophysis of moss is
Answer : Option A
Explaination / Solution:
The sporophyte of moss is differentiated into three parts – foot, seta and capsule. The capsule in turn is differentiated into 3 regions a) apophysis- the sterile basal portion of capsule, it is in continuity with seta b) theca or body of capsule, which is the fertile region, and c) operculum the apical region of capsule .
Apophysis is rich in chloroplast and thus photosynthetic region of moss , it also provides nutrition to the developing sporangium .

Q7.
A stone thrown from the top of a building is given an initial velocity of 20.0 m/s straight upward. Determine the time in seconds at which the stone reaches its maximum height. g =9.8 m /
Answer : Option B
Explaination / Solution:
Initial velocity u = 20.0 m/s
At maximum height it ll stop
So final velocity v = 0 m/s
Acceleration due to gravity g = 9.8 m/s2
Time taken to reach maximum height = t
We know
v = u + at
=>
[g is taken negative because it is in opposite direction of motion.]
Q8. Wavelength of the wave is the distance between two particles of the medium having a phase difference of
Answer : Option C
Explaination / Solution:
No Explaination.
