List I | List II | ||
---|---|---|---|
A | Nucleolus | I | Site of formation of glycolipid |
B | Centriole | II | Organization like the cartwheel |
C | Leucoplasts | III | Site for active ribosomal RNA synthesis |
D | Golgi apparatus | IV | For storing nutrients |
The question involves matching biological components in List I with their functions or characteristics in List II.
List I | List II |
---|---|
Nucleolus | Site for active ribosomal RNA synthesis (III) |
Centriole | Organization like the cartwheel (II) |
Leucoplasts | For storing nutrients (IV) |
Golgi apparatus | Site of formation of glycolipid (I) |
This gives us the pairings:
Thus, the correct answer is: A-III, B-II, C-IV, D-I

4. | Guttation | s. | Ability of water to rise in thin tubes. |
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
