Given a maximum magnetic field gradient of 40 mt/m and magnetic field of 3t, how homogenous must the magnet be (in parts per million) to enable a spatial resolution of 1 mm to be acquired.

The answer is  a.first and third quarters 

Hypothesis. why don’t you know this? i learned this stuff in like 5th grade

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.
