Here are the solutions to your questions:

1. The drugs barbiturates are

   • Barbiturates are powerful sedative-hypnotic drugs that require a prescription. Therefore, they are Prescription Only Medicine.
   • b) POM

2. Reserpine Obtained from plant

   • Reserpine is an alkaloid obtained from the Rauwolfia serpentina plant.
   • a) Rauwolfia

3. Digoxin is obtained from plant

   • Digoxin is a cardiac glycoside obtained from the Digitalis purpurea (foxglove) plant.
   • b) Digitalis

4. Thyroxin is obtained from

   • Thyroxin (thyroxine) is a hormone naturally produced by the thyroid gland in animals.
   • c) Animal Source

5. Insulin are obtained from

   • Insulin, a hormone, was historically obtained from animal pancreases. Modern insulin is often produced using recombinant DNA technology in microbes, but the natural biological source is animal.
   • a) Animal Source

6. Sex hormones are obtained from

   • Sex hormones (e.g., estrogen, testosterone) are naturally produced in animals.
   • a) Animal Source

7. Amoxicillin is obtained from

   • Amoxicillin is a penicillin-type antibiotic that is chemically modified from a naturally occurring penicillin nucleus, making it a semi-synthetic drug.
   • c) Semi-Synthetic Source

8. Ciprofloxacin is obtained from

   • Ciprofloxacin belongs to the fluoroquinolone class of antibiotics, which are entirely synthetic compounds.
   • a) Synthetic Source

9. Paracetamol is

    • b) Cohesive Force

12. Force of attraction between a liquid and a solid surface is known as

    • Adhesive force is the attractive force between molecules of different substances.
    • b) Adhesive Force

13. The force action over the surface of the liquid per unit length of the surface is known as

    • Surface tension is defined as the force acting per unit length on the surface of a liquid.
    • b) Surface Tension

14. The unit of surface tension is

    • Surface tension is force per unit length, so its SI unit is Newtons per meter.
    • a) Newton per meter (N/m)

15. Surface tension increase with ______ in inter molecular forces

    • Stronger intermolecular forces (cohesive forces) lead to higher surface tension.
    • a) Increase

16. Surface tension decrease with

    • As temperature increases, the kinetic energy of molecules increases, weakening intermolecular forces and thus decreasing surface tension.
    • a) Increase in temperature

17. Emulsifying agent work by

    • Emulsifying agents (surfactants) work by decreasing the surface tension between two immiscible liquids, allowing them to mix.
    • a) Decreasing the Surface tension

18. Digestion of lipids in duodenum is done by reducing the surface tension by

    • Bile salts act as emulsifying agents in the duodenum, reducing the surface tension of lipid globules to aid digestion.
    • b) Bile Salt

19. The internal resistance of the molecules of any liquid to flow is called

    • Viscosity is a measure of a fluid's resistance to flow.
    • b) Viscosity
