Q.

In incidents of fire in closed areas, deaths are reported due to hypoxia even though the victims are not burnt. What is the reason for this?

1. $C{O}_2$ produced during burning combines with Haemoglobin forming carboxy-haemoglobin resulting in deficiency of oxygen in tissues

2. CO produced during burning combines with Haemoglobin forming carbamino-haemoglobin resulting in deficiency of oxygen in tissues

3. CO produced during burning combines with Haemoglobin forming carboxy-haemoglobin resulting in deficiency of oxygen in tissues

4. All the oxygen gets used up in the burning fire resulting in hypoxia leading to death

Q. Which of the following factors in the alveoli favour the formation of oxyhaemoglobin?

1. Low partial pressure of O${}_2$, lower temperature
2. High partial pressure of CO${}_2$, lesser H${}^{+}$ concentration
3. High H${}^{+}$ concentration, higher temperature
4. High partial pressure of O${}_2$, lesser H${}^{+}$ concentration

Q. Which of the following correctly describes the difference between R and S-strains of Streptococcus pneumoniae (pneumococcus) bacteria in Frederick Griffith’s experiment?

1. Mice infected with the S-strain(virulent) do not develop pneumonia but mice infected with the R-strain(non-virulent) develop pneumonia.
2. The S-strain bacteria produce rough colonies, while the R-strain produces smooth colonies.
3. The S-strain bacteria have a lipid coat while R-strain bacteria have a mucous coat.
4. The S-strain bacteria have a mucous (polysaccharide) coat while R-strain does not.

Q. Blood analysis of a patient reveals an unusually high quantity of carboxyhaemoglobin content. Which of the following conclusions is most likely to be correct? The patient has inhaled polluted air containing high content of _____________.

4. Carbon disulphide
