What is the definition of the independent variable

the only factor that the scientist purposefully changes

The passing of traits from parents to offspring.

maintaining stable internal conditions inside an organism's cells and body

Keeps the system going and brings the body away from normal

What is the correct order of the levels of organization from smallest to largest?

Cells ➝ Tissues ➝ Organs ➝ Organ systems → Organism

What is the role of the integrating center in a feedback loop.

Processes information from the receptor and creates a plan

Which of these correctly describes one of the levels of organization of an animal?

Organs are made of tissues which are made of cells

Graphs should have titles that include the
