Look for transmission fluid leaks near the front or middle of the car, particularly near the transmission filler tube, near the transmission fluid drain hole, at the selector shaft (itâs the rod that connects your gear shift to your transmission), and between the transmission and engine.
Tetrachromacy is the condition of possessing four independent channels for conveying color information, or possessing four types of cone cells in the eye. Organisms with tetrachromacy are called tetrachromats.
There are two major theories that explain and guide research on colour vision: the trichromatic theory also known as the Young-Helmholtz theory, and the opponent-process theory. These two theories are complementary and explain processes that operate at different levels of the visual system.Trichromatic Theory.n fact, as you have seen, both theories are needed to explain what is known about colour vision. The trichromatic theory explains colour vision phenomena at the photoreceptor level; the opponent-process theory explains colour vision phenomena that result from the way in which photoreceptors are interconnected neurally.
