Reason (R): Red muscles fibres have more number of mitochondria in them
View answer and explanation
Correct option: D
If A is false, but R is true
Option D (If A is false, but R is true) is correct because red muscle fibers primarily depend on aerobic processes, and they do have a higher number of mitochondria.

Three of the following pairs of the disorder of muscular or skeletal system are correctly matched with their respective description. Select the non-matching pair.
View answer and explanation
Correct option: D
Arthritis - Decreased levels of estrogen is a common cause
Option D (Arthritis - Decreased levels of estrogen is a common cause) is the non-matching pair because while decreased estrogen can contribute to osteoporosis, it is not a direct cause of arthritis.

Assertion: The locomotion of unicellular organisms and multicellular animals show similarities.
Reason: Ciliary, flagellar and amoeboid movements occur only in unicellular organisms.
Reason: Ciliary, flagellar and amoeboid movements occur only in unicellular organisms.
View answer and explanation
Correct option: D
Both Assertion & Reason are false.
Option D is correct because both the assertion and the reason are false. Locomotion similarities exist between unicellular organisms and multicellular animals, and ciliary, flagellar, and amoeboid movements are not exclusive to unicellular organisms.

Statement II: Prolonged activation causes accumulation of lactic acid in a striated muscle.
View answer and explanation
Correct option: D
Both statements I and II are incorrect
Option D (Both statements I and II are incorrect) is correct because fatigue doesn't occur in all striated muscles with prolonged activation, and it's not solely due to lactic acid accumulation.

Assertion: In muscle contraction, length of both A – bands and I – bands decrease
Reason: Both myosin of A – bands and actin of I – bands are contractile proteins and decrease in size during muscle contraction
Reason: Both myosin of A – bands and actin of I – bands are contractile proteins and decrease in size during muscle contraction
View answer and explanation
Correct option: D
A and R are incorrect
Option B (b and c) is correct because statement b is incorrect as calcium binding to troponin unmasks the myosin binding site, and statement c is incorrect as A-bands remain constant during sarcomere shortening.
