B) bacteria
C) fungi
D) prions
E) viruses
Monolayer
A single, tightly packed layer of cells or molecules on a surface, commonly used in scientific studies for various assays and experiments.
Branched Side Chains
Structures in organic molecules where carbon chains branch off from the main chain, particularly relevant in the structure of amino acids and proteins.
Archaea
A domain of single-celled microorganisms that are similar to bacteria in size and simplicity of structure but radically different in molecular organization, often found in extreme environments.
