Answer:
The Orchids is the diversified structures of flowers, in fact, they have unique feature. Even with the pollination, they have several mechanisms of pollination. Few of them include:
1. Few orchids have self-fertilization where the anther converts from solid-state to a liquid state without any aid of an external pollinating agent.
2. In others, self-pollination occurs, when the caudicles dry the pollen fall on the stigma.
3. This happens through an external pollinator resulting in a diversity of species.
4. This is a very special case where the flower attracts the insect to mate with bright petals, odor, and the shape.
5. These types depend on ants and other insects to get pollinated.
6. Here, the pollens release some kind of force, when an insect gets in contact with anther which results in getting away the agent from the flower.

Answer:
Warm front
Explanation:
A warm front is the transition zone of the replacement of a cold air mass by a warm air mass. The pressure centers of warm fronts are usually low and the pressure read by a barometer will decrease due to an incoming warm front
The general direction of motion of warm fronts is from southwest to northeast with warmer and moist air behind the warm front than air into which the front flows. Therefore, warm fronts normally results in moderate precipitation or rainfall or snow.
The half-life of a radioisotope is the amon the symbol 42He, the subscript 2 is the mass number for helium and the superscript 4 is the atomic number for helium.
