The process of
prenatal development occurs in three main stages and they are listed in order;
<span>1. </span>Germinal Stage - begins at conception when the
sperm and egg cell joined in one of the two fallopian tubes.
<span>2. </span>Embryonic Stage - begins at the beginning of
the third week after conception. This stage plays an important role in the
development of the brain.

Answer:
1. Slash and Burn agriculture refers to a technique of farming that requires plants in a forest or woodland to be decimated to create a cultivable expanse of land.
Some of these plants are usually homes to wild chimpanzees. The more they are cut down, the deeper into the forests they would migrate, that's if they ever find a place like it.
2. When compared to the other primates such as monkeys, baboons, etc their larger body size, puts them at a disadvantage. This is because when they are placed in a restricted space, they need more food which in turn translates to increased height and weight.

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.
