: 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.
In collateral vascular bundles, phloem is situated towards inner side. In monocot stem, cambium is present.
F particles are present in the inner mitochondrial membrane. An electron gradient formed on the inner mitochondrial membrane, forms ATP
Colloidal solutions are stable but colloidal particles do not settle down. Brownian movement counters the force of gravity actively on colloidal particles.
Ciliated epithelium is present in the inner lining of trachea and large bronchi. Ciliary movement propel the mucus and foreign particle towards the larynx.
Bleaching powder reacts with dilute acids to evolve chlorine. The chlorine liberated by the action of dilute acids on bleaching powder is called available chlorine.
An electric motor will have maximum efficiency when back emf becomes equal to half of applied emf. Efficiency of electric motor depends only on magnitude of back emf.
