Malaria is a non transmissible diseases cause by a PROTOCTISTknown as Plasmodium.Plasmodium ovale or plasmodium vivax which is carried in salivary glands of VECTOR known as female anophele mosquito.MOSUITO GETS PLASMODIUM WHEN THEY TAKE A BLOOD MEAL FROM A PERSON ALREADY INFECTED WITH PLASMODIUM AND THEN THAT MOSUITO CARRY THEM IN THEIR SALIVARY GLANDS AND WHEN MOSQUITO FEED ON ANOTHER PERSON WHO IS UNINFECTED,PLASMODIUM GETS TRANSMITTED IN HIS BLOOD.
PLASMODIUM HAS COMPLEX LIFE CYCLES THATS WHY NO VACCINE HAS BEEN PRODUCED FOR IT.
IT ALSO HIDES IN LUMEN OF INTESTINE TO PREVENT RECOGNITION BY CELLS I GUESS (NOT SURE ABOUT THIS ONE) WHICH IS KNOWN AS ANTIGENIC CONCEALMENT .PLASMODIUM SYMPTOMS OCCUR WHEN MEROZOITES ARE RELEASED FROM RBC.PLASMODIUM MULTIPLY IN RBCS AND WHEN THEY ARE TOO MUCH RBS BURST!. CHLOROQUININE AND MEFLOQUINE ARE COMMON DRUGS TO CONTROL NOT CURE MALARIA
THERE IS MUCH MORE BUT I THINK THIS IS ENOUGH TO ANSWER MCQ QUESTIONS

CHANGE IN WAVELENGHT AFFECTS MAGNIFICATION NOT RESOLUTION.
LESS WAVELENGHT OF OBJECT THEN RESOLUTION THEN OBJECT WILL NOT BE VISIBLE.
CHANGING EYEPIECE LENSES DOES NOT CHANGE RESOLUTION
SOME GOOD POINTSS TO REMEMBER

If they ask for social aspects,then you have to include tourism for your answer as I stated blood transfusion from tourist or migrant can cause malaria to go out of hand and difficult to control it as plasmodium PROTOCTIST WILL spread in other person blood
BUT IF THEY DON'T SPECIFICALLY ASK FOR IT DON'T CHOOSE TOURISM MIGRATION ETC
