Chapter 1: An Introduction to the Human Body
,1. Which of the following best describes the relationship
between a homeostatic feedback loop and a receptor?
A) The receptor interprets input and initiates a change.
B) The receptor monitors changes in a controlled
condition and sends input to a control center.
C) The receptor executes the final response to alter the
controlled condition.
D) The receptor sets the range of values within which a
controlled condition should be maintained.
Answer: B) The receptor monitors changes in a controlled
condition and sends input to a control center.
Rationale: Receptors are monitoring structures that
detect stimuli (changes in the environment) and send
afferent signals to the control center. The control center
,evaluates this input, while effectors bring about the actual
response.
2. A surgeon makes an incision that divides the body into
unequal right and left sides. This slice is along which
plane?
A) Midsagittal plane
B) Parasagittal plane
C) Transverse plane
D) Frontal plane
Answer: B) Parasagittal plane
Rationale: A sagittal plane divides the body into right and
left sides. If it divides the body into equal halves, it is
midsagittal. If the right and left sides are unequal, it is a
parasagittal plane.
, Chapter 2: The Chemical Level of Organization
3. What type of chemical bond is formed when atoms
share electrons unequally due to differences in
electronegativity, such as in a water molecule?
A) Nonpolar covalent bond
B) Polar covalent bond
C) Ionic bond
D) Hydrogen bond
Answer: B) Polar covalent bond
Rationale: Polar covalent bonds occur when electrons are
shared unequally between atoms. In water, the highly
electronegative oxygen atom pulls electrons closer to
itself than the hydrogen atoms do, creating partial
charges.
