Multiple Choice
How does the winding dilemma affect flocculent spirals?
A) The winding dilemma is the basic cause of the chaotic structure in flocculent spirals.
B) The winding dilemma affects only galaxies with flat rotation curves and constant stellar speeds, as in Figure 16-5 of Discovering the Universe, 10th ed., and this does not include flocculent spirals.
C) Flocculent spirals are dominated by self-propagating star formation in which groups of stars are formed and then fade as the massive luminous stars complete their life cycles. This transient, spotty star formation pattern is unaffected by the winding dilemma.
D) Flocculent spirals have a whirlpool structure with several centers of rotation, each affected by the winding dilemma. This results in the overall flocculent pattern.
