NAS 2 CHALLENGE FINAL TEST 2026
QUESTIONS WITH VERIFIED ANSWERS
GRADED A+
◉ What are the steps of the Scientific Method. Answer: 1. problem
2. hypothesis
3. procedure
4.analyze
5.conclusion
◉ Independent Variable. Answer: The experimental factor that is
manipulated; the variable whose effect is being studied.
◉ Dependent Variable. Answer: The outcome factor; the variable that
may change in response to manipulations of the independent variable.
◉ Control Groups. Answer: groups whose members do not obtain the
treatment, while other conditions are held constant
◉ Experimental Groups. Answer: treatment groups; the participants in a
study that receive the intervention
, ◉ Define Anatomy and Physiology. Answer: Anatomy: the study of the
body's parts or the body's structure
Physiology: the sturdy of how the body parts work or how the body
functions
Structure determines function; function determines structure - they're
inseparable.
◉ The six levels of organization. Answer: chemical, cellular, tissue,
organ, organ system, organism
◉ Requirements of life. Answer: water, food, oxygen, heat, pressure
◉ Survival needs. Answer: nutrients, oxygen, water, body temperature,
atmospheric pressure
◉ Homeostasis. Answer: A tendency to maintain a balanced or constant
internal state; the regulation of any aspect of body chemistry, such as
blood glucose, around a particular level
◉ Basic mechanism for homeostasis. Answer: receptor, control center,
effector
