Both Assertion A and Reason R are correct, and R is the correct explanation of A. About 20–25% of CO$_2$ is transported in the blood as carbaminohaemoglobin. The formation of carbaminohaemoglobin is favored by high pCO$_2$ and low pO$_2$, conditions that prevail in the tissues.
Interpret the given diagrams A and B. Enlist the changes occurring during inspiration and expiration.
Select and rewrite the appropriate disorder of the respiratory system based on the given symptoms:
Given disorders: \[ {[ Sinusitis, Emphysema, Silicosis and Asbestosis, Laryngitis ]} \]
(a) Breakdown of alveoli, shortness of breath.
(b) Inflammation of the sinuses, mucous discharge.
(c) Inflammation of larynx, vocal cords, sore throat, hoarseness of voice, mucous build-up,
and cough.
(d) Inflammation of fibrosis, lung damage.
Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector
\(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.
In the light of the above statements, choose the correct answer from the options given below :
