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.
Some cross-pollinated plants are anemopholous, or wind-pollinated. These plants tend to have inconspicuous flowers and produce a lot of pollen, because wind currents cannot selectively identify which plants are receptive to specific pollen.On the other hand, flowers pollinated by insects (entomophilous flowers) often advertise themselves. One way to advertise is by colors.ose pollen, for instance, contains a fragrance profile separate from the rest of the flower, but fragrances from the rest of the flower usually overpower pollen fragrances. As you may have noticed in your travels around the garden after a rain, flower fragrances are often stronger when the air is humid.
