Mark the incorrect statement.

The number of $RBCs$ in man increases if he lives at a higher altitude; this is because

For completion of the respiration process,write the given steps in sequential manner.
$(a)$ Diffusion of gases ($O_2$ and $CO_2$) across alveolar membrane.
$(b)$ Transport of gases by blood.
$(c)$ Utilisation of $O_2$ by the cells for catabolic reactions and resultant release of $CO_2$.
$(d)$ Pulmonary ventilation by which atmospheric air is drawn in and $CO_2$ rich alveolar air is released out.
$(e)$ Diffusion of $O_2$ and $CO_2$ between blood and tissues.

In humans,respiration occurs in the following steps. Arrange these steps in the correct order.
$A$. Diffusion of $O_2$ and $CO_2$ between blood and tissues
$B$. Diffusion of $O_2$ and $CO_2$ across alveolar membrane
$C$. Pulmonary ventilation by which atmospheric air is drawn in and $CO_2$ rich alveolar air is released out
$D$. Cellular respiration
$E$. Transport of gases by the blood

Which of the following two changes occur in humans when they move to high altitudes (above $3,500 \ m$)?
$(1)$ Increase in red blood cell size
$(2)$ Increase in red blood cell production
$(3)$ Increase in breathing rate
$(4)$ Increase in thrombocyte count

What is the last step involved in respiration?
