CEM 141 PRACTICE EXAM QUESTIONS WITH VERIFIED ANSWERS Which has a larger atomic radius? Mg or Ar? Why? A. Mg, because it is a metal. B. Mg, because its valence electrons are not as strongly attracted towards the nucleus as those in Ar. C. Ar, because it is a heavier element. D. Ar, because it has more electrons and they repel each other. B Out of Na+, Mg2+, Ne, and F- which has the smallest radius? A. Na+ B. Mg2+ C. Ne D. F- B When and where were the carbon and oxygen at...

functions of the membrane correct answer: -the structure of the membrane is key for its function -act as a barrier regulating import and export of molecules -help with compartmentalization of the cell, creating particular environments for certain processes so multiple specialized processes could occur at once -modulates cell-cell recognition with their glycoproteins and glycolipids located on the outer leaflet facing the cytosol -signaling across the membrane by proteins and lipids p...
