Question 1

The state government, despite its efforts, finds its resources and legislative powers inadequate to contain the crisis effectively and seeks broader intervention. In this context, which of the following mechanisms could enable the Union Parliament to legislate on a subject typically falling under the State List to address this public health emergency?

B. The Rajya Sabha passes a resolution by a two-thirds majority declaring it necessary in the national interest. — Article 249 allows Parliament to legislate on a State List subject if the Rajya Sabha declares, by a two-thirds majority, that it is necessary or expedient in the national interest.

Question 10

Which of the following statements regarding the stereochemistry of drugs is most accurate?

Accepted Answer

C. Stereoisomers can exhibit different pharmacokinetic profiles and pharmacodynamic effects. — Stereoisomers, especially enantiomers, can interact differently with chiral biological targets (receptors, enzymes), leading to different pharmacokinetic profiles (absorption, distribution, metabolism, excretion) and pharmacodynamic effects (activity, potency, side effects). Enantiomers do not always have identical activity; one enantiomer is often more active, or they might have different activities. Diastereomers are not mirror images and are not superimposable.

Answer

A. Enantiomers always have identical pharmacological activity and potency.

Answer

B. Only racemic mixtures are therapeutically active, never pure enantiomers.

Answer

D. Diastereomers are mirror images of each other and are superimposable.
