Hemophilia (heem-o-FILL-ee-ah) is a rare bleeding disorder in which the blood doesn't clot normally. If you have hemophilia, you may bleed for a longer time than others after an injury.
Aphids: There are five species of aphids commonly found on apples: apple grain aphid, rosy apple aphid, apple aphid, spirea aphid and the woolly apple aphid. The aphid species can be identified by their color, the time of year when they are present and by differences in the cornicles, which are small paired projections from the rear of aphids.
The most used and well known apple tree is the Orchard Apple tree (Malus domestica). There are about 30 to 55 species of apple trees (depending on which type of botanical taxonomic classification method used), of which most are small flowering deciduous trees and some grow as shrubs. Species of the Malus genus are commonly known as crabapples, crab apples, crabs, or wild apples.
