Question : 5

(skipped)

A person suffering from a disease caused by Plasmodium experience recurring chills and fever at the time when

Options:

	The microgametocytes and megagametocytes destroy by WBC
	The sporozoites released from RBCs are being rapidly killed and broken down in spleen
	The trophozoites reach maximum growth and release certain toxin without undergoing multiple fission
	The parasite after its rapid multiplication inside RBC rupture then releasing the stage that enters the fresh RBC as well as the release of haemozoin

Solution :

Chills, shivering and high fever are due to the release of haemozoin in blood after rupturing of RBC.

Question : 10

(skipped)

Male Anopheles does not transmit malarial parasite because

Options:

	The parasite is digested in its stomach
	It is too small to carry parasite
	It lacks blood sucking mouth parts
	It is warm blooded so the maturation of gametocytes does not take place

Solution :

Male Anopheles does not suck blood. Male mosquitoes do not have piercing and sucking type of mouth parts.
