Answer:
"nucleus" seems to be the correct answer.
Step-by-step explanation:
- The nucleus seems to be a significant case wrapped through a double membrane that distinguishes these from the cytoplasm, the nuclear shell. The membranes combine throughout a few areas, allowing the interchange of substances between some of the cytoplasm as well as the nucleus, steps given designated "nuclear pores".
- The nuclear shell is consistent with either the concentrated endoplasmic reticulum, thereby bonding with either the nucleus.
