Mixing in diffiation phase

What is phase ?

The respiratory activity in "cell maturation" phase as compared to other phases is

In a stationary wave (A) All the particles of the medium vibrate in phase (B) All the antinodes vibrate in phase © All alternate antinodes vibrate in phase (D) All the particles between consecutive nodes are in phase

An ideal solution is prepared by mixing of A ( P_A^@ = 90 Torr) and B ( P_B^@ = 15 Torr) in which mole fraction of A in liquid phase is 0.6. Then mole fraction of B in vapour phase is [X]xx10^(-1) . Then value of X is

Which phase corresponds to the interval between the mitosis and initiation of DNA replication? (a.) S phase (b.)M phase (c.)G_(1) phase (d.)G_(2) phase

A : G_(2) -phase pre-mitotic phase. R : Chromosomes undergo condensation in this phase.

Two waves arrive at a point in opposite phase , possible phase differences is
