Given below are two statements: Statement I: Failure of segregation of chromatids during cell cycle, resulting in the gain or loss of whole set of chromosome in an organism, is known as aneuploidy. Statement II: Failure of cytokinesis after anaphase stage of cell division resulting in the gain or loss of chromosome is called polyploidy. In the light of the above statements, choose the correct answer from the options given below:
In a growing population of a country,
An ionised H-molecule consists of an electron and two protons. The protons are separated by a small distance of the order of angstrom. In the ground state: (a) the electron would not move in circular orbits. (b) the energy would be 2⁴ times that of a H-atom. (c) the electron's orbit would go around the protons. (d) the molecule will soon decay in a proton and a H-atom. Choose the correct option:
The ratio of the radii of gyration of a circular disc to that of a circular ring, each of the same mass and radius, around their respective axes is:
In terms of Bohr radius a₀, the radius of the second Bohr orbit of a hydrogen atom is given by
$4.0 \text{ gm}$ of gas occupies $22.4 \text{ litres}$ at NTP. The specific heat capacity of the gas at a constant volume is $5.0 \text{ J K}^{-1}\text{mol}^{-1}$. If the speed of sound in the gas at NTP is $952 \text{ ms}^{-1}$, then the molar heat capacity at constant pressure will be: ($R=8.31 \text{ J K}^{-1}\text{mol}^{-1}$)

Given below are two statements: Statement I: Mendel studied seven pairs of contrasting traits in pea plants and proposed the Laws of Inheritance. Statement II: Seven characters examined by Mendel in his experiment on pea plants were seed shape and colour, flower colour, pod shape and colour, flower position and stem height. In the light of the above statements, choose the correct answer from the options given below:
An inductor of inductance L, a capacitor of capacitance C and a resistor of resistance R are connected in series to an AC source of potential difference V volts. The potential difference across L, C and R is 40 V, 10 V and 40 V, respectively. The amplitude of the current flowing through the LCR series circuit is $10\sqrt{2}$ A. The impedance of the circuit will be:
If $Z_1$ and $Z_2$ are the impedances of the given circuits (a) and (b) as shown in the figures, then choose the correct option:
The electrostatic force between the metal plates of an isolated parallel plate capacitor C having a charge Q and area A, is
