Answer 1

QUESTION 7: when an animal cell is placed in a hypertonic solution, the water will move from cell to the extracellular fluid i.e from region of low osmolarity to region of high osmolarity, resulting in shrinking of the animal cell.

Correct answer is (c)

QUESTION 8 :

Protons - 116

Neutrons - 177

QUESTION 9: In the given reaction , sulphur loses 2 electrons and undergoes oxidation.

Correct option is (b)
