EMB agar Only gram-negative bacteria grow on EMB agar. (Gram-positive bacteria are inhibited by the dyes eosin and methylene blue added to the agar.) Based.
Monosaccharides (CH 2 O) n If n=3, triose (glyceraldehyde) If n=5, pentose (ribose) If n=6, hexose (glucose, galactose) Monosaccharides are used for –Energy.
1 Organic Compounds Compounds that contain CARBON are called organic. Macromolecules are large organic molecules. Macromolecules.
1. Carbon is the second most abundant element in living organisms. 2.Carbon can share four electrons, therefore it can bond to four additional atoms.
PH, Acids, Bases, and Buffers. Solutions Solute + Solvent = Solution In nature, water is a major solvent. Concentration – measured in moles Molarity –
