B Correct answer
Explanation

Probiotics are live beneficial bacteria that promote gut health when consumed. They're found in fermented foods like yogurt, kefir, and sauerkraut. Prebiotics are non-digestible fibers that feed probiotics, while antibiotics kill bacteria (both good and bad).

Multiple choice general knowledge science & technology
  1. clotrimazole

  2. Diflucan

  3. triazoles

  4. Fluconazole

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Zocon (brand name) contains Fluconazole, which is a triazole antifungal medication used to treat fungal infections. Clotrimazole is also an antifungal but is a different drug (imidazole derivative). Diflucan is actually a brand name for Fluconazole itself. 'Triazoles' refers to a class of drugs, not a specific medication.

Multiple choice general knowledge science & technology
  1. Alexander Fleming

  2. Guglielmo Marconi

  3. Tim Berners-Lee

  4. Elias Howe

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Alexander Fleming discovered penicillin in 1928 when he noticed mold killing bacteria in a petri dish. This revolutionized medicine and earned him the Nobel Prize. Guglielmo Marconi invented radio, Tim Berners-Lee created the World Wide Web, and Elias Howe invented the sewing machine.

Multiple choice general knowledge science & technology
  1. Pathogenesis

  2. Psittacosis

  3. Antibiotics

  4. Tetratex

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Antibiotics are medications specifically designed to treat bacterial infections by killing bacteria or inhibiting their growth. Pathogenesis is the disease development process, psittacosis is a specific bacterial disease, and Tetratex is not a standard antibiotic term.

Multiple choice general knowledge
  1. True

  2. False

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Despite the spelling error 'medicene' instead of 'medicine', this statement correctly describes antimicrobial resistance. Antimicrobial resistance occurs when microorganisms change and become resistant to medications that previously worked against them. The definition provided is accurate according to WHO standards.

Multiple choice
  1. Quinine

  2. Penicillin

  3. Chloroquine

  4. Anti–Tetanus Serum

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Penicillin is an antibiotic obtained from the fungus ‘Penicillium notatum’ and it works against bacteria. Quinine and chloroquine are drugs which are used to treat malaria. Anti-Tetanus Serum (ATS) is a vaccine used to prevent tetanus. None of these is obtained from fungus and hence, they are not antibiotics.
