The plasmodia parasite that causes malaria enters the human body through the bite of an infected Anopheles mosquito, reports Drugs.com. These parasites infect the liver cells and reproduce, causing the cells to burst open, explains WebMD.
The output of the VCR when playing an NTSC cassette in NTSC 4.43 mode is 525 lines/29.97 frames per second with PAL compatible heterodyned color. The multi-standard receiver is already set to support the NTSC H & V frequencies; it just needs to do so while receiving PAL color.
Other differences are found in the resolution and frequency of the signal. NTSC uses 525 scan lines, of which 486 are visible. NTSC also uses 29.97 interlaced FPS or frames per second, this is done on a signal with frequency of ~60Hz. PAL on the other hand does not set exact format for these things in its specifications, although it uses a pretty standard format. PAL most commonly has 625 scan lines, of which 576 are visible.
