to show how some fixed quantity is broken down into parts

Explanation:

First Question (about what describes nature's happenings)

A scientific law is a statement that describes what happens in nature and is always true under specific conditions. A hypothesis is a proposed explanation, a theory is a well - supported explanation, and a variable is a factor in an experiment. So the correct answer is scientific law.

A line graph is best used to show trends and how data changes over time. Making observations and gathering information is part of data collection, not the purpose of a line graph. Compassing information by counting is related to tallying or simple counting methods. Showing how a fixed quantity is broken down into parts is the purpose of a pie chart.

Answer:

scientific law (the option corresponding to "scientific law")
