Which of the following does not have optical isomer?

The temperature dependence of rate constant $(k)$ of a chemical reaction is written in terms of Arrhenius equation $k=A e^{-E_{\alpha} / R T}$. Activation energy $\left(E_{a}\right)$ of the reaction can be calculated by ploting

Agranulocytes are

Equipment used for the measurement of growth in plants is known as :

Acid hydrolysis of sucrose is a

The number of atoms present in unit cell of a monoatomic substance of simple cubic lattice is:

According to Einstein?? photoelectric equation, the plot of the kinetic energy of the emitted photo electrons from a metal Vs the frequency, of the incident radiation gives straight line whose slope

Okazaki is known for his contribution to the understanding of

Abscisic acid is known as the stress hormone because it

Polyembryony is observed in plants like Mango. Nucellar cells develop into the embryos. Which of the following is true?

A wire of length $L$ metre carrying a current of $I$ ampere is bent in the form of a circle. Its magnetic moment is,

A wire of length L, area of cross section A is hanging from a fixed support. The length of the wire changes to $L_1$ when mass M is suspended from its free end. The expression for Young?? modulus is:

A wire of length $l$ carries a steady current. It is bent first to form a circular plane loop of one turn. The magnetic field at the centre of the loop is $B$. The same length is now bent more sharply to give a double loop of smaller radius. The magnetic field at the centre caused by the same is

When a substance ' $A$ ' reacts with water, it produces a combustible gas ' $B$ ' and a solution of substance ' $C$ ' in water. while another substance ' $D$ ' reacts with solution of ' $C$ ' to produce the same gas $B$ on warming while ' $D$ ' can produce gas ' $B$ ' on reaction with dilute $H _{2} SO _{4}$ at room temperature. ' $A$ ' imparts a deep golden yellow colour to a smokeless flame on Bunsen burner. Identify 'A', $' B$ ', ' $C$ ' and ' $D$ ' respectively are

Which of the following is a function of ethylene?

A transformer with efficiency 80% works at $4\, kW$ and $100\, V$. If the secondary voltage is $200\,V$, then the primary and secondary currents are respectively
