ANSWERS & EXPLANATIONS

Ans.1. A. A straight line starting from zero with positive slope g. This comes from the kinematic equation $v_y=u_y+gt$, where $u_y=0$ for horizontal projection. Since g is constant, the resulting graph is a straight line from the origin, indicating uniformly accelerated motion in the vertical direction.

Ans.2. B. The V-I graph is a straight line passing through the origin. This option reflects the direct proportionality between potential difference and current, which is the essence of Ohm’s law. Ohm’s law states V= IR, where R is constant for an ohmic conductor at constant temperature.

Ans.3. A. directed downward. This follows from conservation of energy: the gravitational potential energy gained going up is fully converted back into kinetic energy when coming down, giving the same speed at the same height in an ideal, frictionless system.

Ans.4. C. 9 A.

Ans.5. B. Virtual, erect, and larger on the same side of the lens. This matches the behavior of a convex lens acting as a magnifier when the object is placed within the focal length.

Ans.6. A. Decreasing temperature and increasing pressure. This combination directly supports the exothermic direction and compresses the system toward the side with fewer gas moles, maximizing ammonia production under equilibrium conditions.

Ans.7. C. Strong hydrogen bonding between water molecules. Water molecules form extensive intermolecular hydrogen bonds due to the high electronegativity of oxygen and the presence of lone pairs on oxygen. Each water molecule can form up to four hydrogen bonds: two through its hydrogen atoms and two via its lone pairs.

Ans.8. A. Ethanol, $C{H}_{3}C{H}_{2}OH$. Ethanol has $C_2{H}_{6}O$, can be oxidized to ethanal, and therefore yields a positive iodoform test, matching both the formula and reactivity described.

Ans.9. B. The active site has a specific shape that fits only particular substrates. Enzymes are biological catalysts whose specificity mainly arises from the three-dimensional structure of their active site. The active site has a complementary shape and chemical environment that bind only certain substrates through precise interactions like hydrogen bonding, ionic interactions, and hydrophobic effects.

Ans.10. B. pH = 5, the solution is acidic. Because pH is below 7, the solution has excess hydrogen ions compared to neutral water and therefore behaves as an acid in an aqueous medium.

Ans.11. D. Arteries carry blood away from the heart; veins carry blood towards the heart.

Ans.12. C. It is triplet, non-overlapping, and nearly universal. Three-base codons allow for $4^3=64$ combinations, enough to code for 20 amino acids and stop signals, and the same code applies widely across species.

Ans.13. C. Dilation of afferent arteriole supplying the glomerulus. By increasing blood flow and hydrostatic pressure in the glomerulus, this change directly promotes a higher GFR in healthy kidneys.

Ans.14. B. Mitosis produces genetically identical diploid cells, while meiosis produces genetically variable haploid cells. This properly distinguishes the two processes based on chromosome number and genetic consequences.

Ans.15. D.  Mitochondria – ATP production through aerobic respiration. Ribosomes handle protein synthesis, whereas DNA replication is carried out by enzymes in the nucleus and organelles containing their own DNA.
