In genetics and biotechnology, metabolic engineering and inheritance dictates that exogenous gene introduction and pathway extension enable trait improvement. Therefore T-type Ca ion channels is correct as it demonstrates metabolic extension and combinatorial biosynthesis, supported by mechanistic studies and conserved across related systems.

Ref: Pierce, Genetics: A Conceptual Approach, 6th Edition, Chapter 3, discusses genotype-phenotype correlation and inheritance patterns providing framework for genetic transmission and metabolic engineering.

When Tetrodotoxin is administered in bathing medium of a nerve fibre during voltage clamp experiments the membrane curre

This outcome reflects quantitative reasoning, where ratio, percentage and series logic determine correct calculation. Option B captures this correctly because it meets mathematical and logical criteria, consistent with textbook descriptions and experimental observations in aptitude and reasoning.

Ref: Agrawal, Quantitative Aptitude for Competitive Examinations, Chapter 5, Logical Reasoning and Probability, covers ratios, percentages, series completion, time-distance and analytical reasoning explaining problem-solving strategies for competitive assessments.

The changes in the electrical potential of a neuron that constitute the action potential occur in the following order

bioenergetics and thermodynamics analysis shows internal energy, enthalpy and pressure-volume work describe evaporation and combustion. Consequently resting potential –> depolarization-> hyperpolarization – > resting potential emerges as the valid choice since it satisfies first law and physiological energetics, aligning with established principles in physiology and thermodynamics literature.

Ref: Atkins and de Paula, Physical Chemistry, 11th Edition, Chapter 2, First Law, explains internal energy, enthalpy, work, heat and energy changes in chemical reactions like ethanol combustion providing thermodynamic foundation.
