MCQ
For two statements are given $-$ one labelled Assertion $(A)$ and the other labelled Reason $(R).$ Select the correct answer to these questions from the codes $\ce{(a), (b), (c)}$ and $(d)$ as given below :
Assertion : The Bowman's capsule and the tubule together make a nephron.
Reason : The function of tubule is to allow the selective reabsorption of substances like glucose, amino acids, urea, salts and water into the blood capillaries.
  • A
    Both $A$ and $R$ are true and $R$ is correct explanation of the assertion.
  • B
    Both $A$ and $R$ are true but $R$ is not the correct explanation of the assertion.
  • ✓
    $A$ is true but $R$ is false.
  • D
    $A$ is false but $R$ is true.
✓

Answer

Correct option: C.
$A$ is true but $R$ is false.
The function of tubule of nephron is to allow the selective reabsorption of the useful substances like glucose, amino acids, salts and water into the blood capillaries. The waste materials like urea remains behind in the tubule. It does not get reabsorbed into blood capillaries.
