Some flowering plants have a long pistil that reaches way above the lower petals. what’s the purpose of this structure?

To receive pollen grains

Explanation:

A flower is a modified shoot which is meant for reproduction. The stamen is the male reproductive organ and the pistil is a flower's female organ. A pistil is located in the centre of the flower and is surrounded by petals, sepals and stamens.

Some flowers have a long pistil that reaches above the petals to receive wind disseminated pollen grains. This helps transfer pollen and fertilize the ova in the ovaries.

yes its like the dead sea which is full of salt which makes you stay afloat

so yes an egg will float in salt

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
