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.
Insect pollinated plants will have flowers, usually with nectar, to attract the insects and reward them with food. A bee's body is covered with fine hairs which become charged with static electricity as the insect flies so when it lands on the flower the pollen grains are actually attracted to the bee's body.
