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.

A

Explanation:

Due to the inhibition of convection by the magnetic fields, these areas (usually occur in pairs corresponding to the two poles), the hot plasma from the sun’s interior doe not reach the surface of these areas hence creating local regions that are cooler than the rest of the photosphere. This cooler regions appear darker when observed with a telescope and are called sunspots.

Support Frame

Explanation:

The cytoskeleton is the set of filaments and very thin tubules of proteins present in the cytosol of cells, responsible for the support and shape, allowing their movement and transport of substances. Symbolically, it has cellular functioning similar to the skeleton and musculature. In addition, it can be described as "support frame".

Its composition is basically structured by two types of protein filaments: microfilaments and microtubules, enabling an extremely dynamic conformation that is continuously restored, aggregating and disaggregating its constituents.
