Not only does its name anticipate the American document of a century later, the English Bill of Rights anticipates some of the American billâs specific provisionsâfor example, the Eighth Amendmentâs ban on excessive bail and fines and on cruel and unusual punishment.
If the leaf contains carotene, as do the leaves of birch and hickory, it will change from green to bright yellow as the chlorophyll disappears. In some trees, as the concentration of sugar in the leaf increases, the sugar reacts to form anthocyanins. These pigments cause the yellowing leaves to turn red.
Chlorophyll is also what gives plants their green color. As summer ends and autumn begins, the days get shorter and shorter. With fewer daylight hours, leaves are not able to make as much chlorophyll as they can during the long daylight hours of spring and summer. As the chlorophyll fades, we are able to see other colors, such as orange and yellow, emerge. Many people mistakenly believe that weather makes leaves change color.
