Match List I with List II:
Choose the correct answer from the options given below:
To remember these components:
• Centromere plays a key role in cell division,
• Cilium aids in cell movement,
• Cristae are structures within mitochondria,
• The cell membrane is composed of a phospholipid bilayer.
The correct matches are:
(A) Centromere is involved in Cell division (II).
(B) Cilium is involved in Cell movement (III).
(C) Cristae are found in Mitochondrion (I).
B Cell membrane consists of Phospholipid Bilayer (IV).
Thus, the correct matches are: \(A - II, \quad B - III, \quad C - I, \quad D - IV\)
Consider a water tank shown in the figure. It has one wall at \(x = L\) and can be taken to be very wide in the z direction. When filled with a liquid of surface tension \(S\) and density \( \rho \), the liquid surface makes angle \( \theta_0 \) (\( \theta_0 < < 1 \)) with the x-axis at \(x = L\). If \(y(x)\) is the height of the surface then the equation for \(y(x)\) is: (take \(g\) as the acceleration due to gravity)
A constant voltage of 50 V is maintained between the points A and B of the circuit shown in the figure. The current through the branch CD of the circuit is :
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 :
