APHY 101 MIDTERM EXAM – LATEST (MOST TESTED & DIFFICULT)
Total Questions: 50 (Long & Conceptual)
Coverage: Cells, Membranes, Tissues, Integumentary, Skeletal, Muscular, Nervous, Homeostasis
1. Cellular Transport (HIGHLY TESTED)
A patient receives an IV solution that causes red blood cells to swell and rupture. Which mechanism best
explains this outcome?
A. Active transport increased intracellular sodium
B. Osmosis caused water influx due to hypotonic solution
C. Facilitated diffusion of glucose increased cytoplasmic pressure
D. Endocytosis increased membrane permeability
Correct Answer: B
Rationale: Hypotonic solutions cause water to move into cells via osmosis, leading to hemolysis.
2. Homeostasis & Feedback Loops
Following blood loss, heart rate increases and blood vessels constrict to maintain blood pressure. This is
an example of:
A. Positive feedback
B. Negative feedback
C. Feedforward regulation
D. Neural reflex inhibition
Correct Answer: B
Rationale: The response counteracts the disturbance, restoring homeostasis.
, 3. Plasma Membrane Structure
Which membrane component is MOST responsible for regulating membrane fluidity?
A. Phospholipids
B. Integral proteins
C. Cholesterol
D. Glycoproteins
Correct Answer: C
4. Cellular Organelles
A cell with high ATP demand would have an increased number of:
A. Ribosomes
B. Lysosomes
C. Mitochondria
D. Golgi apparatus
Correct Answer: C
5. Tissue Identification
Which tissue type lines the alveoli and allows rapid gas exchange?
A. Stratified squamous epithelium
B. Simple cuboidal epithelium
C. Simple squamous epithelium
D. Pseudostratified columnar epithelium
Correct Answer: C
6. Connective Tissue
Which connective tissue provides resistance to stretching and attaches muscle to bone?
A. Ligament
B. Tendon
C. Cartilage
D. Areolar tissue
Correct Answer: B
