Describe the ionization states of all ionizable groups if this peptide were in a solution of pH 6.
What is the net charge of the peptide at this pH?
At a pH of 6, which of the amino acid residues within the pentapeptide are fully deprotonated?
which are fully protonated? which are partially ionized?

Match each law or principle to its description. 1. law of original horizontality sediment continues to spread in a flat plane until it hits an edge or runs out of material. 2. law of superposition the youngest strata are at the top and the oldest are at the bottom. 3. law of original lateral continuity sediment gets pulled down by gravity in a horizontal and flat layer. 4. law of cross-cutting or intrusive relationships if there is a fracture or intrusive feature seen in rock strata, it is younger than the rock strata.
