A major characteristic of the monocot root is the presence of :

Vascular bundles in monocotyledons are considered closed because:

Select the correct matching in the following pairs:

The chromosomes in which centromere is situated close to one end are:

True nucleus is absent in :-

An organic compound ′X′ having molecular formulaC5H10O yields phenyl hydrazone and gives negativeresponse to the Iodoform test and Tollen′s test. Itproduces n-pentane on reduction. ′X′ could be :-

The reaction is called :-

The species Ar, K+ and Ca2+ contain the same number of electrons. In which order do their radii increase ?

Which of the following pairs of ions are isoelectronic and isostructural ?

Which of the following is the most correct electron displacement for a nucleophilic reaction to take place?

A resitance ′R′ draws power ′P′ when connected to an AC source. If an inductance is now placed in series with the resistance, such that the impedance of the circuit becomes ′Z′, the power drawn will be:

One mole of an ideal diatomic gas undergoes a transition from A to B along a path AB as shown in the figure, The change in internal energy of the gas during the transition is :

Consider 3rd orbit of He+ (Helium), using non-relativistic approach, the speed of electron in this orbit will be [given K = 9 × 109 constant, Z = 2 and h (Planck)′s Constant) = 6.6 × 10-34 Js]

Figure below shows two paths that may be taken by a gas to go from a state A to a state C. In process AB, 400 J of heat is added to the system and in process BC, 100 J of heat is added to the system. The heat absorbed by the system in the process AC will be :

If energy (E), velocity (V) and time (T) are chosen as the fundamental quantities, the dimensional formula of surface tension will be :
