. Great earthquakes usually begin with slight tremors but ---- take the form of one or more violent shocks, and end in vibrations of gradually diminishing force called aftershocks.
Answers
Answer:
Electromeric effect refers to a molecular polarizability effect occurring by an intramolecular electron displacement characterized by the substitution of one electron pair for another within the same atomic octet of electrons. The dispersal of seeds by wind is called as anemochory. For anemochory, the seeds should be lightweight and should have some morphological features as wings, hairs, etc.
Madar and cotton seeds do not show presence of wings.
As stated above, seeds should be lightweight as well as should possess some morphological features for anemochory. Madar and cotton seeds show a dense coating of hairs around their testa. It enables the seeds to float in air.
Therefore, the correct answer is option D.
