Question 13
SURVEY
30 seconds
Q.
A researcher placed a sample of purified lipid in a test tube containing water. She observed the formation of spherical micelle structures in the solution. Ultrastructural analysis of the micelles showed a light outer shell and a denser inner core.

The researcher hypothesizes that the lipid micelles are held together by non-covalent interactions. She tests this hypothesis by vigorously agitating the solution. Which of these observations would provide the STRONGEST support for her hypothesis?
answer choices
The number of micelles decreases, and the size of the micelles decreases.
The number of micelles increases, and the size of the micelles decreases.
The number of micelles decreases, and the size of the micelles increases.
The number of micelles increases, and the size of the micelles increases.
