UNIT 1: LEVELS OF ORGANIZATION
CHAPTER 1: AN INTRODUCTION TO THE HUMAN BODY — 18 Questions
Q1. Which of the following lists the levels of structural organization in the correct order from
simplest to most complex?
A. Cellular, Chemical, Tissue, Organ, Organ System, Organism
B. Chemical, Tissue, Cellular, Organ, Organ System, Organism
C. Chemical, Cellular, Tissue, Organ, Organ System, Organism
D. Organ, Tissue, Chemical, Cellular, Organ System, Organism
Correct Answer: C
Rationale: The chemical level is the most basic building block (atoms/molecules), which
combines to form the cellular level. Cells group to form tissues, tissues combine to form
functional organs, organs work together in organ systems, and all systems make up the
complete organism.
Why Wrong: A, B, D — These all place the levels in the incorrect order.
---
Q2. What organic compound do brain cells primarily rely on for metabolic fuel?
, A. Fatty acids
B. Glucose
C. Amino acids
D. Glycerol
Correct Answer: B
Rationale: Although the body can break down fats and proteins for energy, neurons in the
brain rely almost exclusively on glucose for cellular respiration and ATP production under
normal physiological conditions.
Why Wrong: A, C, D — These are not the primary fuel source for brain cells under normal
conditions.
---
Q3. In a negative feedback loop, which component is responsible for processing incoming
data and determining the appropriate response?
A. Sensor
B. Effector
C. Stimulus
D. Control center
Correct Answer: D
Rationale: The control center (often the brain or endocrine glands) evaluates information
received from the sensor, compares it against the physiological set point, and signals the
effector to make a change.
Why Wrong: A — The sensor detects changes. B — The effector carries out the response. C
— The stimulus is the initial change.
