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.
  Self-Pollination   If the pollen lands on stigma of the same flower, it is called self-pollination.   Cross-Pollination   When the pollen of a flower lands â¦ on the stigma of another flower of the same plant, or that of a different plant of the same kind, it is called cross-pollination.he flowers produce both  female and male parts. When the bee or ot â¦ her insect lands to drink  the nectar, some pollen is deposited on his body. As he goes on to  other flowers, the pollen is then transferred to the female parts.  Once there, it travels to the ovary where pollination occurs.
