Organization
Stem
A student studying for an exam draws a diagram that nests
molecules → organelles → cells → tissues → organs → organ
systems → organism. They later encounter a paragraph
describing how the contractile proteins actin and myosin enable
skeletal muscle contraction allowing limb movement. Which
,level of organization best links the molecular description to the
organismal function in this example?
A. Cellular
B. Tissue
C. Organ
D. Organ system
Correct answer: B
Rationale — Correct (B)
Tissues are assemblies of similar cells plus their extracellular
components that perform a specific function. The contractile
proteins (molecular level) within muscle cells (cellular) organize
into muscle tissue whose coordinated contraction produces
movement; thus the tissue level bridges molecular/cellular
mechanisms to organ/organ-system actions.
Rationale — Incorrect
A. Cellular — The cellular level is important, but the stem
emphasizes coordinated cells forming a functional unit (muscle
tissue).
C. Organ — An organ (e.g., biceps) is composed of multiple
tissue types; the immediate bridge described is tissue.
D. Organ system — Organ systems are higher-level integrations
that depend on tissues and organs; this choice is too broad.
Teaching point:
Tissues integrate similar cells and extracellular material to
produce specific, higher-level functions.

Homeostasis and Physiological Regulation
Stem
During a physiology lab, a subject’s core temperature rises
above normal after vigorous exercise. The hypothalamus
initiates sweating to increase heat loss. Which statement best
identifies the type of homeostatic control and explains how it
maintains internal stability?
A. Positive feedback — sweating amplifies the original change
to restore baseline temperature.
B. Negative feedback — sweating reduces the stimulus (high
temperature) to return toward normal.
C. Positive feedback — sweating is self-limiting and stops when
temperature reaches set point.
D. Negative feedback — sweating elevates body temperature to
counteract heat loss.
Correct answer: B
Rationale — Correct (B)
Sweating is a negative-feedback response: the hypothalamus
, detects an increase in core temperature and triggers effector
mechanisms (sweating and vasodilation) that reduce body
temperature, thus opposing the original stimulus and
promoting stability.
Rationale — Incorrect
A. Positive feedback — Incorrect; positive feedback amplifies a
change rather than opposing it.
C. Positive feedback — Incorrect; sweating does not amplify the
rise in temperature and is not self-amplifying.
D. Negative feedback — Incorrect; sweating does not elevate
temperature, it promotes heat loss.
Teaching point:
Negative feedback opposes deviations from set points; sweating
cools the body to restore thermal balance.
