How to Hard-Boil an Egg. Hard-boiling eggs is almost as easy as boiling water, if you know the right process: Cooking eggs too long or too vigorously can result in cracked shells, tough whites, and green-gray, sulfuric-smelling yolks.
Although all flowering plants rely on pollination for reproduction, there is a variation in how plants pollinate. There are two types of pollination called self-pollination and cross-pollination. Self-pollination is the more basic type of pollination because it only involves one flower.
Pollination is the reason plant species are able to survive from generation to generation. Whether carried by insects, birds, animals or wind, pollen makes its way from the male flowers to the female flowers to begin the reproduction process. But this movement is only the beginning. After pollination there is a flurry of activity that leads to the production of a new plant.
