Q3. The number of chromosome and the amount of DNA are changed in
Answer : Option A
Explaination / Solution:
S phase marks the period during which DNA synthesis or replication takes place. During this time the amount of DNA per cell doubles. If the initial amount of DNA is denoted as 2C then it increases to 4C.and even in anaphase the chromosome numbers are changed.1
Q4. Magnitude of displacement of a particle is
Answer : Option C
Explaination / Solution:
The maximum possible value for displacement is the distance travelled, so it cannot be of a greater value than distance (path length).
The magnitude of the displacement is always less than or equal to the distance traveled. If two displacements in the same direction are added, then the magnitude of their sum will be equal to the distance traveled.
Q5. The activity of the iron catalyst used in Haber’s process is adversely affected due to presence of
Answer : Option D

Q9. The importance of the elastic behavior of materials is
Answer : Option D
Explaination / Solution:
More the elastic a material is , more it has the property to regain its original position which is required in construction works.
Q10. Host cell membrane can be made permeable by
Answer : Option B
Explaination / Solution:
CaCl2 can be used to make the bacterial cell a permeable cell, and by introducing these cells (after CaCl2 being placed into the mixture of bacterial cells), a plasmid for ampicillin resistance can be transformed into the bacteria. The standard method for making the bacteria permeable to DNA involves treatment with calcium ions.
