How does a monarch protect itself?
Monarchs feed almost exclusively upon plants in the milkweed family, and toxic chemical compounds (cardiac glycosides) from the plants give the insect an unpleasant taste. The black and yellow stripes on the caterpillar and the striking black and orange colours of the adult serve as a warning to potential predators: "You don't want to eat me." Predators quickly learn to leave the Monarch alone. Another butterfly, the Viceroy, mimics the adult colours and pattern of the Monarch in an effort to fool predators into thinking it, too, tastes bad, even though it does not feed upon milkweed and therefore does not contain the bad-tasting compounds.
What are the three types of receptor cells in the retina?
Rods and cones are the ones involved in actually seeing. Rods detect mostly black and white, though they might detect some blue. The cones are the color receptors, and they have 3 subtypes to detect long, medium, and short wavelengths of visible light. There is a third type, photosensitive ganglion cells. They are important for entrainment and reflexive responses to the brightness of light..
