16. which of the following explanations accounts for the
formation of sunspots?
o a. the curvature of magnetic fields near the sun's equator creates
pockets in the photosphere that aren't warmed by convection.
b. magnetic field reversal causes portions of the sun to die slowly
over time, leaving dark marks.
o c. the movement of plasma is much faster on the poles than on the
sun's equator, and this creates pockets of intense heat.
od. volcanic eruptions are sustained by the photosphere, resulting in
hardened lava on the sun's surface.

Based on the observations provided, what is the relationship of current diabetes medication use and the use of extract from ginko biloba? a) the anti-inflammatory properties of ginko biloba extract are beneficial in treating t2d separate from the benefits of other therapies. b) the overall abundance of ginko biloba makes this extract an attractive joint therapy for existing medications that are used to treat t2d. c) the side effects of t2d medications have resulted in the need for different therapies to treat t2d like the use of ginko biloba extract. d) clinical outcomes from the use of current t2d medications may be improved through the use of cost-effective ginko biloba extract treatment. e) previous studies with ginko biloba and current t2d medications do not support the use of these treatments as effective against t2d in patients.
