Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
The original roots of dodder usually die. As a parasitic plant that cannot produce its own chlorophyll, it breaks away from its root system as the roots has no apparent root cap nor apical meristems. Hence the "root" is not performing its very function of water and nutrient uptake. It then produces haustoria, a root-shaped fungi which penetrates host plant which makes the dodder parasitic.
This one would be amplitude. The reason is because amplitude is the distance from the center of the wave to the farthest point on the wave. So, if the amplitude of a wave is, say, 5m, the distance between the center of the wave and the top (or bottom) would be 5 meters. And to find the total height, just double the amplitude.
