Which statement is an inference rather than an observation?

Genetic code for inheritance
Using energy
Which sequence correctly orders the levels of biological organization?

Some people think fire is alive because it can grow and spread. Based on the eight characteristics of life, why is this belief incorrect?
Fire does not use energy.
Fire does not have cells or DNA.
Fire cannot change its environment.
Fire reproduces on its own.
You are given two unknown samples: one is alive and one is not. Which set of tests would best determine which is living?
Check for DNA, growth, and response to stimuli
Test for temperature and mass
Measure size and weight
Test for color and smell
