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.
Cross-pollination is more complex than self-pollination because it requires the movement of pollen from one flower to another flower. There are several strategies that flowering plants utilize to move pollen from one flower to another, including wind, water, and animal pollinators.
