A. It is an exact substitute for a living thing or real-life event.
O
B. It is always easier to do than an actual experiment.
O
C. It can help predict the outcome of an event.
O
D. It allows a scientist to avoid making any observation of the natural
world.

The answer is it is an exact substitute for a living thing or real-life event.

Explanation:

Simulation is the process of imitation of the operation or system that represents its operation over time. it can be used to explore changes in a low risk environment. The simulation is used in many applications.

It is the re-creation of a real world process in a controlled environment. They are used for scientific exploration, for safety tests, and to create graphics for video games and movies.

Simulation software is used to design equipment because the product will be close to design without expensive in process.

The simulation process comes under three types live, virtual, and constructive.

Live: simulation involving real people operating real system

virtual: simulation involving real people operating simulated system.

Constructive: simulation involving simulated people operating simulated systems.

tissue

explanation:

it is actually formed by geoup of cells which is tissue

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
