The nucleus has a system of embedded within its outer membrane which allows communication between the nucleus interior and the cytoplasm.

pores

Explanation:

The nucleus consists of "nuclear pores" on its outer membrane. Each of these are surrounded by nuclear pore complex. It allows the pore to regulate the movement of molecules between the nucleus and the cytoplasm. It allows small particles to pass through such as ribosomal proteins. It prevents most large particles (except for histone) from passing through; thus, it is selective in nature. This function of the pores clearly shows that it allows communication to occur between the nucleus interior and the cytoplasm.

idk

explanation:

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
