Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Let's evaluate each statement:
(A) "The eukaryotic ribosomes are 80S and prokaryotic ribosomes are 70S" is correct. Eukaryotic ribosomes are 80S, whereas prokaryotic ribosomes are 70S in size.
(B) "Each ribosome has two sub-units" is correct. Ribosomes are made up of two sub-units.
(C) "The two sub-units of 80S ribosome are 60S and 40S while that of 70S are 50S and 30S" is incorrect. The correct sub-units for 80S ribosome are 60S and 40S in eukaryotes, while 70S ribosomes are made up of 50S and 30S sub-units.
(D) "The two sub-units of 80S ribosome are 60S and 20S and that of 70S are 50S and 20S" is incorrect. The sub-units of 80S ribosome are 60S and 40S, and those of 70S ribosome are 50S and 30S.
(E) "The two sub-units of 80S are 60S and 30S and that of 70S are 50S and 30S" is correct. Thus, the correct answer is A, B, E are true.
(B) "Each ribosome has two sub-units" is correct. Ribosomes are made up of two sub-units.
(C) "The two sub-units of 80S ribosome are 60S and 40S while that of 70S are 50S and 30S" is incorrect. The correct sub-units for 80S ribosome are 60S and 40S in eukaryotes, while 70S ribosomes are made up of 50S and 30S sub-units.
(D) "The two sub-units of 80S ribosome are 60S and 20S and that of 70S are 50S and 20S" is incorrect. The sub-units of 80S ribosome are 60S and 40S, and those of 70S ribosome are 50S and 30S.
(E) "The two sub-units of 80S are 60S and 30S and that of 70S are 50S and 30S" is correct. Thus, the correct answer is A, B, E are true.

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)
