Assertion and Reason Type Questions:In the questions given below, the...
Assertion (A) : Toothpaste cleans our teeth.
Reason (R) : The sparkle in some toothpastes comes from mica.
The correct answer is option 'A', which states that both the assertion (A) and the reason (R) are true, and the reason (R) is the correct explanation of the assertion (A).
Explanation:
Toothpaste is a common oral hygiene product that is used to clean and maintain the health of our teeth. It contains several ingredients that work together to achieve this purpose. One of the key ingredients found in some toothpastes is mica, a mineral that provides a sparkle or shimmering effect.
Assertion (A) : Toothpaste cleans our teeth.
This assertion is true. Toothpaste contains mild abrasives that help remove plaque, stains, and food particles from the surface of our teeth. It also contains detergents that create foam and help in the mechanical cleaning process. Additionally, toothpaste often contains fluoride, which strengthens the tooth enamel and helps prevent tooth decay.
Reason (R) : The sparkle in some toothpastes comes from mica.
This reason is also true and provides an explanation for the assertion. Mica is a natural mineral that is often used in toothpaste to give it a shiny or sparkling appearance. The addition of mica particles to toothpaste does not affect its cleaning properties, but rather enhances its visual appeal. The sparkle created by mica in toothpaste is purely cosmetic and does not play a direct role in the cleaning process.
Conclusion:
The assertion that toothpaste cleans our teeth is supported by the reason that the sparkle in some toothpastes comes from mica. Mica is added to toothpaste for its aesthetic value and does not impact the cleaning properties of the toothpaste. Therefore, both the assertion and the reason are true, and the reason correctly explains the assertion.
