Correct Answers Anabolism
________________ is the breakdown of macromolecules for
energy (e.g. sugars, proteins, lipids) Correct Answers
Catabolism
__________________ are normal microbiota that cause disease
under certain circumstances. Correct Answers Opportunistic
pathogens
__________________ is the ability to distinguish two points
that are close together. The better it is, the better two nearby
objects are distinguished from one another. Correct Answers
Resolution (resolving power)
Note: Different types of microscopes have different resolving
powers.
