Answer: This is because the same type of crop planted repeatedly in the same area keeps draining the land of the same nutrients needed for that plant's growth.
Explanation:
The greater the force that produces a wave, the greater the amplitude of the wave and the greater the energy carried by the wave. In a transverse wave the higher the wave, the higher the amplitude. Sounds with greater amplitude will be louder; light with greater amplitude will be brighter
in 1913 Niels Bohr proposed that electrons move in orbits around the nucleus such as the planets orbit around the sun
False; a radiation even should lead to many branches (many new species).
