A professor wanted to find a correlation between screen time and his student's chemistry test scores. He had 4 groups of students that routinely got Cs and Bs in their classes. 1 group got 5 hours of screen time per week, 1 group got 15 hours of screen time per week, another got 25 hours of screen time per week, and the last group got 0 hours of screen time per week.
An organism's ability to self-regulate its internal environment
Homeostasis
Creates the cell membrane
Phospholipids
How do enzymes speed up chemical reactions?

Until the 1980s, many classroom skeleton models were made with this.
Real human bone
What is the difference between a control group and a constant?
Control Group: Does not receive treatment. Baseline for comparison. Isolates the effect of the independent variable.
Constant: Factors that must remain the same across all experimental groups to ensure the results can be attributed to the effects of the independent variable
