S4. Ans.(a)
Sol. Tidal Volume (TV): The volume of air inspired or expired during a normal respiration is called Tidal Volume. It is approximately 500 ml in a healthy man.
S5. Ans.(b)
Sol. Calcium ions (Ca2+) are essential for blood clotting. They are required by the enzyme thrombin which catalyzes one of the first steps of blood.
