what is a system?
○ a set of interacting parts forming a complex whole
○ a single component that functions independently of others.
○ a collection of random elements with no interconnections.

Explanation:

First Question (What is a model in science?)

• Option A: Models in science are not toys; they are conceptual or representational tools, so this is incorrect.
• Option B: Scientific models simplify complex or large - scale phenomena (like atomic models for atoms or climate models for the Earth's climate) to make them understandable, which matches the definition of a scientific model.
• Option C: The set of rules scientists follow in experiments is experimental procedure or scientific method guidelines, not a model.
• Option D: A model is not a map of a laboratory; it is about representing scientific phenomena.

• Option A: A system is defined as a set of interacting parts that together form a complex whole (e.g., an ecosystem with interacting organisms, or a computer system with interacting hardware and software components).
• Option B: A single component functioning independently is not a system, as systems require multiple interacting parts.
• Option C: A collection of random elements with no interconnections is just a collection, not a system, as systems rely on interactions between parts.

Answer:

B. A simple way to represent or explain something that's too big or too complicated to see easily
