D. The plant can’t reproduce. The reason a plant has a flower is for reproduction. The attractive smell and color of the flower attract pollinators. These pollinators eat nectar from the flower and get covered in pollen. They then transport the pollen to other flowers were the pollen is used by the other plant to produce seeds. The seeds are the way that the plant reproduces. Option A) doesn’t make sense because absorbing water is done by the roots. Option B) doesn’t make sense because that is done in the plants leaves. And C) doesn’t make sense because the plant supports itself using the stem. So the answer must be D)
an oscillator consisting of a material point of m = 200g vibrates under the action of an elastic force according to the equation y = 0.2sin (π / 4 • t + π / 16) (m)
calculate the period and frequency of the oscillation
