In this animated object, learners examine how changes in pH affect the salt bonds in strands of hair.
In this overview, students examine and identify mannitol positive and mannitol negative bacteria on mannitol salt agar.
Learners read this review of chemical hair bonds after completing learning objects on the peptide, disulfide, salt, and hydrogen bonds. Students may e-mail their quiz answers to their instructor.
Students read about the process of hair growth beginning with the joining together of amino acids.
Learners view movie clips to determine the solubility of two ionic compounds. They also examine a solubility chart and predict the solubility of compounds.
