Flowering plants reproduce sexually through a process called pollination. The flowers contain male sex organs called stamens and female sex organs called pistils. Cross-pollination happens when the wind or animals move pollen from one plant to fertilize the ovules on a different plant.
I think it is D. because the sun's radiant energy gives life to the earth life forms.
It must go through the plasma membrane
The appropriate answer is D. a river floods over its channel banks and deposits sediment on the wide valley bottom.
Flood plains usually develop along the lower course of the river. The lower course has a gentle gradient and so the flow of water is not fast and therefore the bed load of the river gets deposited. Rivers carry materials such as boulders, pebbles, gravel, sand, silt and clay. The larger size materials will get deposited upstream while the finer material will travel to the lower course.
The glacier melt each year increases the volume of the river so it will overflow its banks and deposit materials in layers on the flood plains. Materials on the flood plain are usually fine such as sand and silt.
