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.

There are four more phases that occur during meiosis than mitosis.
Meiosis and Mitosis undergo the same phases: prophase, metaphase, anaphase and telophase. The difference between the two is the number of stages, wherein mitosis only has one stage while meiosis has two. Meiosis has stage 1 with prophase I, metaphase I, anaphase I, telophase I and stage 2 with prophase II, metaphase II, anaphase II and telophase II.
I believe the answer is C
Hope this helps you have a good night
