As you complete DAY 14 of your daily practice, take a few minutes to analyze your mistakes, revise weak areas, and note down important concepts. Remember, scoring 650+ in NEET UG 2026 isn’t about studying more, it’s about practicing smart and staying consistent every single day. Keep showing up, trust the process, and come back tomorrow for the next set of high-yield questions that will keep you moving forward with confidence and clarity.

ANSWERS & EXPLANATIONS

Ans.1. D. A straight line with negative slope starting at $u$u and decreasing linearly to -u. Since acceleration due to gravity g is constant and downward, we use v = u-gt (taking upward as positive). This linear relation shows that velocity decreases steadily as the stone rises, becomes zero at the top, and then becomes increasingly negative as it falls back. Thus, the velocity-time graph must be a straight line with constant negative slope, not a flat horizontal line.

Ans.2. A. Work and torque. Both quantities share the dimensional formula $[M{L}^2{T}^{-2}]$ since they result from force multiplied by a distance, even though their physical interpretations differ.

Ans.3. B. A straight line with a negative slope starting at u and crossing zero, then becoming negative. In vertical motion under gravity near Earth’s surface, acceleration is nearly constant and downward with value g. 

Ans.4. C. 1.6m. On a smooth (frictionless) incline, the only force component opposing the motion along the plane is the component of weight, mgsinθ.

Ans.5. D. 4000N. From $v^2=u^2+2as$, with the given values, we derived $a=-4{\text{m s}}^{-2}$. Then, using F = ma, the required braking force magnitude is $1000\times 4=4000\text{N}$. This ensures that the kinetic energy of the car is removed over the specified distance without requiring an excessively large force, which would otherwise imply a much shorter stopping distance.

Ans.6. A. The enzyme has high affinity for the substrate. In Michaelis-Menten kinetics, $K_m$ is inversely related to the affinity of enzyme for substrate under certain assumptions. A small $K_m$means that the enzyme–substrate complex forms readily and remains stable enough for catalysis, so high reaction rates can be achieved even at low substrate levels, a key point for NEET biochemistry questions.

Ans.7. D. Ethane. The mechanism involves radical formation from carboxylate ions, decarboxylation. Two such radicals couple to produce ethane, a saturated molecule. Any unsaturated products like alkenes are minor or arise from different conditions, so the main expected product for NEET-level questions is ethane.

Ans.8. A. The amine has one fewer carbon than the amide. The mechanism involves formation of an N-bromoamide, followed by rearrangement where the alkyl or aryl group migrates from carbonyl carbon to nitrogen, and the carbonyl carbon is lost as a carbonate or carbon dioxide equivalent. As a result, a primary amine is formed whose carbon chain is shorter by one carbon, making this reaction useful for stepping down carbon chain length in synthetic sequences.

Ans.9. C. The change in internal energy is zero. In a cyclic process, the system’s thermodynamic state after a complete cycle is the same as at the beginning, so all state functions, including internal energy, return to their initial values.

Ans.10. C. From n=2 to n=1

Ans. 11. C. RBCs will shrink and become crenated due to exosmosis. When the extracellular fluid is hypertonic, water leaves the cells to balance osmotic pressure, causing them to shrink and distort in shape. This passive water movement is driven by osmotic gradients and does not involve active pumping of salt by the RBCs.

Ans.12. A. Mitosis produces genetically identical daughter cells, while meiosis generates genetic variation. Meiosis fosters variation by including synapsis, crossing over, and random assortment of homologous chromosomes, whereas mitosis preserves genetic identity across cell generations.

Ans.13. B. Lichen stage → Moss stage → Herbaceous stage → Shrub stage → Forest. Lichens are pioneer species that can colonize bare rock, secrete acids, and contribute to soil formation. Mosses follow, further trapping dust and moisture to deepen the soil layer. Then, herbaceous plants (grasses and herbs) establish, adding organic matter and improving soil structure. Shrubs succeed them, and finally trees dominate, forming a stable climax forest community, a classic ecological succession sequence often asked in NEET.

Ans.14. B. A decrease in ${\text{H}}^{+}$ concentration (rise in blood pH). Reduced acidity (more alkaline blood) diminishes the stimulatory effect on the respiratory centres, leading to slower, shallower breathing until normal pH is restored.

Ans.15. A. A nonsense mutation introducing a premature stop codon. This leads to early termination of translation and a truncated, usually non-functional protein, which can severely affect the phenotype.
