In physical science there are two types of "isolated systems"
1. Being a Physical System in which it is so far removed from other systems that it does not react with any of them.
2. Being a Thermodynamic System in which it is enclosed by rigid immovable walls of which neither mass nor energy can flow through.
I believe in this case although not stated that it would refer to a Thermodynamic System which would leave you with the only plausible answer as ENERGY AND MATTER CANNOT ENTER OR LEAVE.
None of the other answers make sense. Even if it were referring to Physical. Physical does not react with anything at all. An as you can see Thermodynamic does not allow for anything to pass through or leave.
Answer:
92 chromatids
Explanation:
During phosphate, the nuclear envelope of the cell (which is where the 92 chromatids are contained) begins to break down. The centrioles, which are the only present in animal cells, separate and each moves to an opposite end of the cell
It is called a Phagocytic cell
