Answer» If both the assertion and the reason ate true but the reason is not correct explanation of the assertion If both the assertion and the reason ate true and the reason is a correct explanation of the assertion If the assertion is true but the reason is false If both the assertion and reason are false Solution :When the mosquito bites man, sporozoites present in the salivary gland of female Anopheles mosquito are injected into the blood of the man. The erythrocytic schizont gives rise to merozoites. Malaria fever occurs when schizonts in red blood corpuscles burst and set FREE their contained merozoites and malarial pigment (HAEMOZOIN) in the blood plasma. Bursting of schizonts TENDS to be synchronous as they all burst at the same time. Haemozoin is said to be toxic and so includes high fever and shivering (Haemozion is an unused hematin, which is PRODUCED by the breakdown of HAEMOGLOBIN). It is yellow brown to blackish in colour.
