Halley's Comet
As of now, there are no spacecraft missions planned to travel to Halley's Comet. The last time it was visited by a spacecraft was in 1986 by the ESA's Giotto mission. The comet is currently not within reach of any existing spacecraft technology.
The comet now known as Halley's Comet has been observed since at least 240 BCE, but it was not known to be something that reappeared periodically. It wasn't until 1705 that English astronomer Edmond Halley determined that it was the same comet that appeared periodically.
Chromatin material is contained within the nucleus.
Protons and neutrons reside within the nucleus, electrons orbit around the nucleus.
Protons are contained within the nucleus, electrons surround the nucleus at a considerable distance (atomically speaking)

Chromatin material is contained within the nucleus.
The Nucleolus?
None. The nucleus IS and organelle.
No, they spin within the nucleus.
None. The nucleus IS and organelle.
Protons - within the nucleus Neutrons - within the nucleus Electrons - outside the nucleus
The molecules within the nucleus that are important in cell reproduction is DNA .
Protons and neutrons reside within the nucleus, electrons orbit around the nucleus.
No, the nucleus is a membrane-bound organelle that houses the cell's genetic material, including the nucleolus. The nucleolus is a region within the nucleus where ribosomal RNA synthesis and ribosome assembly occur.
