Answer:
The correct answer is "negative".
Explanation:
At pH 2 the net charge of the R groups of all the amino acids that comprise the peptide in question would be positive. This happens because of the high content of protons in a solution of pH 2, a value that is below the isoelectric point of all the amino acids. Since the peptide would have a positive net charge, it would migrate to the negative terminal of the gel because opposite charges attract each other.

Answer:
This question have two parts.
Question 1. Is a 0.185 M aqueous solution of sodium sulfate, Na2SO4, hypertonic, hypotonic or isotonic to red blood cells?
Answer:
Hypotonic because sodium sulfate is a detergent which can cross the lipid bi-layer.
Question 2. If normal red blood cells were suspended in this Na2SO4 solution, what would be the expected outcome?
Answer:
Hemolysis (Bursting of Red blood cells) will occur due to excessive movement of water inside the cell resulting from sodium sulfate solution.
