d.none of the above
Explanation / Answer
19. c.
An injury to outer surface of bone causes local infection which results in reaction that may cause expansion of bone's diameter. This reaction is the periosteal reaction.
20. b.
The bacteria present in the mouth naturally digests the carbohydrates and the end product of such digestion is lactic acid. Lactic acid is responsible for dissolving teeth enamel due to which carries are formed.
21. d.
This condition is mainly caused due to parasitic infection or iron deficiency.
22. c.
Perfectly round will help the bone to have a uniform surface area on all sides and hence the strength is also equal.
23. d.
It affects all the points stated in options.
24. a.
Modern development has caused increased probability of occurrence of such fractures as the surface underneath is hard and any fall taken can result in hip being fractured.
25. d.
The shift occurs overall in dietary patterns and not characterized by the given options. Hence the answer is none of the above.
