Explain why scientists use shared characteristics to make cladograms.

How does a coronal mass ejection (cme) affect the solar wind? a cme adds more particles to the solar wind, intensifying it. a cme blocks the solar wind, causing it to fade. a cme does not affect the solar wind but it does affect auroras. a cme increases the amount of energy in the solar wind.

The molar mass of cu is 63.55 g/mol. the number of grams of cu produced in this reaction is
