Answer 1

In malaria, the product release by mosquito into blood that cause chill and fever is called

schuffner's dot

rhizotoxin

hematin

haemozoin

Answer: Haemozoin

Reason for the answer: Haemozoin is released by malarial parasite Rhodnius and Schistosoma which digest it and release a Heme which is a non protein component of haemoglobin.

Answer 2

The correct answer is D. Haemozoin

Malarial parasites, that is, Plasmodium vivax, suck blood from the host and digest the haemoglobin.

But after that they give out free heme particles which is the non-protein constituent of haemoglobin.

Since the free heme particles are harmful, the malarial parasites transform the heme particles into a crystalline structure that is not soluble in blood and is known as haemozoin.
