Electron microscopy

Based on the manual guide, select the true statements.

• We don't have to prepare, JUST DO IT.

• Decide the organelles that we want to examine.

• Solutions need be prepared before sample collection.

• Electron microscopy sounds so alien to me.

• We can put the sample as we like, no need to be strict about it.
