Convergent evolution involves the independent evolution of similar traits in different species due to similar environmental pressures. The correct matches are:
Therefore, the correct option is (1): A-III, B-IV, C-II, D-I.
The current passing through the battery in the given circuit, 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
