83 Questions Q1–Q83
Q1 QUESTION 1 OF 400 BIOD 151 Module 1
There are six levels of organization in the body - what are they?
CORRECT ANSWER
1) chemical
2) cellular
3) tissue
4) organ structure
5) organ system
6) organism
RATIONALE
Levels of organization in the body illustrate the structural hierarchy from the simplest
chemical compounds to the complex organism, emphasizing how each level builds upon the
previous one to create functional systems essential for life. Understanding this hierarchy is
for grasping the interrelatedness of body functions and the complexity of biological
systems.

, Q2 QUESTION 2 OF 400 BIOD 151 Module 1
The necessary life function that protects our internal environment from our external
environment is provided by what system?
CORRECT ANSWER
The integumentary system
RATIONALE
The integumentary system serves as a barrier, protecting the body from external pathogens,
chemicals, and physical damage while maintaining homeostasis by regulating temperature
and hydration. This vital function underscores the system's role in safeguarding the internal
environment against external threats.
Q3 QUESTION 3 OF 400 BIOD 151 Module 1
The function of movement is provided by what system?
CORRECT ANSWER
The muscular system
RATIONALE
Movement is facilitated by the muscular system, which generates force through contraction
and relaxation of muscles, allowing for locomotion and manipulation of the environment.
This system works in conjunction with the skeletal system to provide structure and leverage
for efficient movement.

, Q4 QUESTION 4 OF 400 BIOD 151 Module 1
The function of responsiveness is provided by what system?
CORRECT ANSWER
The nervous system
RATIONALE
Responsiveness is primarily mediated by the nervous system, which processes sensory
information and coordinates appropriate motor responses through neural pathways. This
system's rapid signaling enables organisms to react promptly to environmental stimuli,
ensuring survival and adaptation.
Q5 QUESTION 5 OF 400 BIOD 151 Module 1
The function of digestion is provided by what system?
CORRECT ANSWER
The digestive system
RATIONALE
Digestion is the biochemical process of breaking down food into absorbable nutrients,
primarily facilitated by the organs and glands of the digestive system, which includes the
mouth, stomach, intestines, and accessory organs. This system's coordinated actions enable
the mechanical and chemical breakdown of food, essential for nutrient absorption and
energy production.
