ANSWERS & EXPLANATIONS

1. D. 4B

2. A. V = E – Ir

3. D. Horizontal component of velocity: This component is unaffected by gravity because gravity acts only vertically, making horizontal motion uniform throughout the projectile’s trajectory.

4. A. Increasing load resistance and increasing transistor $\beta$

5. D.  Impedance equals resistance and current is maximum. At this point, the circuit absorbs maximum power from the AC source due to the unity power factor and minimal impedance.

6. A. Increasing the concentration of reactants in solution. Higher concentration means more reactant particles per unit volume, which leads to more frequent collisions.

7. B. A curve that decreases exponentially with time, approaching zero asymptotically

8. C. Decreasing the volume of the container at constant temperature: This increases the pressure, and the system responds by favoring the side with fewer gas moles, namely $N_2{O}_4$, to partially counteract the pressure increase.

9. D. They consist of ions held together by strong electrostatic forces in a lattice: The high energy needed to separate these strongly attracting ions accounts for the high thermal stability and elevated phase transition temperatures of ionic compounds.

10. B. This option is correct because a negative Gibbs free energy change (ΔG<0) at constant temperature and pressure characterizes a spontaneous process, one that can proceed in the forward direction without external work. 

11. C. Rete testis → vasa efferentia → epididymis → vas deferens → urethra

12. D. It applies only when genes are located on different, non‑homologous chromosomes or are far apart on the same chromosome: In such cases, dihybrid crosses display independent segregation of the two traits, leading to characteristic phenotypic ratios that reflect the random combinations of alleles from independently assorting genes.

13. C. Secretion of hydrogen ions and reabsorption of bicarbonate ions in the distal convoluted tubule and collecting duct

14. B. Immunity acquired by a fetus through maternal antibodies crossing the placenta: During pregnancy, antibodies from the mother, especially of the IgG class, cross the placenta and enter the fetal bloodstream.

15. B. Photolysis of water in the thylakoid lumen of chloroplasts
