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.
When this is carried out by birds, the term used is Ornithophily. Hummingbirds, spiderhunters, sunbirds, honeycreepers and honeyeaters are the most common pollinator bird species. Plants that make use of pollination by birds commonly have bright red, orange or yellow flowers and very little scent.
