Centipedes are carnivores, they use venom to kill their prey. They are preyed upon by birds, toads and shrews.
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:
The statistical study of populations and how they change over time is called demography. Two important measures of a population are population size, the number of individuals, and population density, the number of individuals per unit area or volume.
Explanation:
Relative dating to determine the age of rocks and fossils. Geologists have established a set of principles that can be applied to sedimentary and volcanicrocks that are exposed at the Earth's surface to determine the relative agesof geological events preserved in therock record.
