735612694How malaria is passed from person to personThe mosquito "bites" a person that has the plasmodium sporozoan in their bloodstream. The plasmodium cells go to the mosquito's salivary glands. Before feeding on the blood of another human, the infected mosquito injects some of its saliva, containing the parasite, into the puncture wound of this new victim. The plasmodium goes to the human liver cells, reproduces quickly, and then enters the bloodstream where they will burst and fully infect the human.

735823699What is countershading in fish and why its importantCountershading is a form of camouflage that protects fish from predators above and below it. The upper half of the fish is dark in color so when viewed from above, it blends with the bottom of the body of water. The lower half of the fish is lighter in color which makes it blend with the lighter water surface.
