When white light passes through a prism, the deviation is maximum for
When phenol reacts with phthalic anhydride in presence of $H _{2} SO _{4}$ and heated and hot reaction mixture is poured in $NaOH$ solution, then product formed is
What is common between chloroplasts, chromoplasts and leucoplasts?
Two heater wires, made of the same material and having the same length and the same radius, are first connected in series and then in parallel to a constant potential difference. If the rates of heat produced in the two cases are $H_s$ and $H_p$ respectively, then $H_s /H_p$ will be
Three point charges $+q,-2 q$ and $+q$ are placed at points $(x=0, y=a, z=0),(x=0, y=0, z=0)$ and $(x=a, y=0, z=0)$, respectively. The magnitude and direction of the electric dipole moment vector of this charge assembly are
The magnifying power of a compound microscope increase with
The flame colours of metal ions are due to
During the life-cycle, Fasciola hepatica (liver fluke) infects its intermediate host and primary host at the following larval stage respectively
When the velocity of projection of a body is made $n$ times, its time of flight becomes $n$ times. Range of projectile does not depend on the initial velocity of a body.
Tropylium cation is aromatic in nature.
The only property that determines its aromatic behaviour is its planar structure.
The magnetic field produced by a current carrying solenoid is independent of its length and cross-sectional area. The magnetic field inside the solenoid is uniform.
The colour of the green flower seen through red glass appears to be dark. Red glass transmits only red light.
: The alternating current lags behind the e.m.f. by a phase angle of $\pi / 2$, when AC flows through an inductor. : The inductive reactance increases as the frequency of $A C$ source decreases.
Replication and transcription occur in the nucleus but translation occurs in the cytoplasm. m RNA is transferred from the nucleus into the cytoplasm where ribosomes and amino acids are available for protein synthesis.
Nuclear endosperm is formed by subsequent nuclear division without wall formation. Coconut is an example of such endosperm, where the endosperm remains nuclear throughout the development of the fruit.
Maize is an albuminous seed. Endosperm is completely absorbed by its growing embryo.
Interferons are a type of antibodies produced by body cells infected by bacteria. Interferons stimulate inflammation at the site of injury.
