1.	Patients with moderate to severe anaemia have a reduced A. Cardiac output. B. Incidence of vascular bruits. C. 2:3-diphosphoglycerate blood level. D. Arterial PO2. E. Capacity to raise oxygen consumption in exercise.
Answer» A. False Output rises to compensate for the blood’s reduced O₂ carrying capacity. B. False Bruits are common since increased flow velocity and decreased blood viscosity increase the likelihood of turbulent flow. C. False 2:3-DPG is increased, shifting the dissociation curve to the right so that blood gives up its oxygen more easily. D. False Arterial PO₂ is normal; it is O₂ content which is reduced. E. True Due to the reduced capacity to deliver O₂ to the muscles.

How do biofertilisers enrich the fertility of the soil?
Read carefully the passage and select the correct answer out of given four options:Biofertilizers are organisms that enrich nutrient quality of the soil.
