This organelle's lamina helps support its shape. Some protists have both a macro and micro version of this organelle. One part of this organelle is the location of ribosome synthesis, while importins and exportins assist in transport in and out of this organelle. This organelle, whose envelope is continuous with the rough endoplasmic reticulum, has pores in its double membrane. Transcription occurs within this organelle, which disappears during mitosis as its chromatin assemble into chromosomes. For 10 points, name the control center of the cell.

Some of the figures in this painting are seemingly superfluous: Mercury stands at the far left, dispelling clouds from above trees laden with golden fruit. A Cupid on the wing aims his little bow, but is probably only there by grace of his mother Venus, above whom he hovers. The action takes place on the right. The West Wind, Zephyrus, pursues a virginal Chloris whom he will rape. Chloris is then shown transformed, bedecked with flowers, as the title character. For 10 points, name this Botticelli allegorical work.
Fine Arts

These objects are thought to provide power to blazars. The rotating versions of these bodies described by the Kerr metric are surrounded by ergospheres from which energy can be gained in the Penrose process, and they can be described by mass, charge, and angular momentum according to the [*] no-hair theorem. They aren't neutron stars, but after exploding in supernovae, stars that have overcome the electron degeneracy pressure of the Chandrasekhar limit can form these objects. Featuring an event horizon at the Schwarzchild radius surrounding a gravitational singularity, for 10 points, name these astronomical objects so massive that no light can escape them.
