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 Paracetamol is the generic name* for the drug, while brand names include Tylenol or Panadol. b) Generic Name* 10. Acetyl Salicylic Acid is Acetyl Salicylic Acid is the chemical name* for Aspirin. c) Chemical Name* 11. The force of attraction between the molecules of the same substance is known as Cohesive force* is the attractive force between molecules of the same substance. 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* 20. The viscosity is measured with the help of A viscometer* is an instrument used to measure the viscosity of a fluid. a) Visco Meter* 21. Following factors affecting viscosity Viscosity is affected by temperature, the size of molecules, the shape of molecules, and intermolecular forces. From the given options, temperature and shape of molecule are factors. d) a & c* 22. Atom is derived from The word "atom" comes from the ancient Greek word* "atomos," meaning "uncuttable" or "indivisible." a) Greek word*
