After taking exam 1, its very easy to see that the questions on the exams require a lot of critical thinking and are much more abstract than a multiple choice and fill in the blank sort of layout. A lot of what we’ve learned and are going to be tested on for exam 2 actually require this critical thinking to simply grasp concepts. Everything we covered in Chemistry seemed to be tied to Biology and vice versa. One concept that encompasses the synthesis of Biology and Chemistry is intermolecular forces and bonding theories within our cells. One question I can predict being on Exam 2 is one in regards to emulsions. Emulsions are the combination of two substances that usually cannot be combined. A question in regards to emulsions could sound something like:
How do our cells achieve emulsion and what forces are responsible for allowing two immiscible substances to be mixed? Which macromolecule is needed in our cells to make this possible? Draw a picture illustrating an emulsion.
