A. Cells are metabolically active and proliferate: This occurs during the G1 phase of the cell cycle, where the cell grows and prepares for DNA replication. A-II
B. DNA replication takes place: This occurs during the S phase (synthesis phase). B-IV
C. Proteins are synthesized: Protein synthesis occurs throughout the cell cycle but is particularly active during the G1 and G2 phases. C-I, and since G1 has already been assigned then it should be G2 making it C-I
D. Cells at the non-dividing stage with metabolically active cells: This describes the G0 phase, a non-proliferating stage where cells remain metabolically active but do not proliferate. D-II
A sphere of radius R is cut from a larger solid sphere of radius 2R as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is : 
AB is a part of an electrical circuit (see figure). The potential difference \(V_A - V_B\), at the instant when current \(i = 2\) A and is increasing at a rate of 1 amp/second is:
Three identical heat conducting rods are connected in series as shown in the figure. The rods on the sides have thermal conductivity 2K while that in the middle has thermal conductivity K. The left end of the combination is maintained at temperature 3T and the right end at T. The rods are thermally insulated from outside. In steady state, temperature at the left junction is \(T_1\) and that at the right junction is \(T_2\). The ratio \(T_1 / T_2\) is
