Question

Consider the following statements.
(a) In muscles, anaerobic respiration produces carbon dioxide, water and energy.
(b) Artificial kidney is a device to remove nitrogenous waste products from blood through dialysis.
(c) Food is translocated inside the plants through phloem.
Which of the above statements are correct?

• A. (a) and (b)
• B. (b) and (c)
• C. (a) and (c)
• D. None of the above

Answer 1

The correct option is B (b) and (c)

In muscles, anaerobic respiration produces lactic acid. Due to lactic acid accumulation, skeletal muscles are fatigued after some time. Hence, statement (a) is incorrect.
Dialysis is an artificial procedure of excretion of metabolites from blood when kidneys do not work. In this process, the harmful waste products are removed from the blood. Hence, statement (b) is correct.
Phloem is conducting tissue of the plant, which is involved in food translocation from leaves to other parts of the plant body. Therefore, statement (c) is correct.
Therefore, option B is correct.
