Answer: C- When preparing the centrifuge for spinning, care must be taken to keep equal balance. If spinning an uneven amount of tubes, filling an empty tube with water (using the same volume as the single tube) and placing it across from the single tube will keep the load balanced. When loading a centrifuge, place tubes across from each other. Tube holders across from each other must match-empty for empty, and tubes containing same volumes across from each other.
