A. $F_1$ Particles: These are ATP synthase complexes found on the inner mitochondrial membrane. They are responsible for the synthesis of ATP during oxidative phosphorylation. A-IV
B. Histones: These are proteins that package and order DNA into structural units called nucleosomes. They are associated with chromosomes. B-I
C. Axoneme: This is the central core of cilia and flagella, responsible for their movement. C-II
D. Cisternae: These are flattened, membrane-bound sacs that are the building blocks of the Golgi apparatus. D-II
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 :
