with Lab | Questions & Answers | 100%
Correct | Grade A - Chamberlain
1. Which type of microscope is best for viewing fine details of a
cell's internal structure?
A. Transmission electron microscope
B. Light microscope
C. Dissecting microscope
D. Phase-contrast microscope
Correct Answer: A
Rationale: TEM uses electrons to visualize ultrastructural details
inside cells.
2. Which objective lens is used first to locate a specimen?
A. Scanning (4x)
B. Low-power (10x)
C. High-power (40x)
D. Oil-immersion (100x)
Correct Answer: A
Rationale: Scanning objective provides a wide field to locate the
sample safely.
,3. Which knob is used to focus a slide under high power?
A. Fine focus
B. Coarse focus
C. Stage adjustment
D. Diaphragm
Correct Answer: A
Rationale: Fine focus allows precise adjustments without damaging
the slide.
4. What is the main function of mitochondria?
A. ATP production
B. Protein synthesis
C. Lipid storage
D. Waste digestion
Correct Answer: A
Rationale: Mitochondria produce cellular energy through
respiration.
5. Which tissue type is avascular and flexible, found at joints?
A. Cartilage
B. Bone
C. Dense connective
D. Adipose
Correct Answer: A
,Rationale: Cartilage receives nutrients via diffusion and cushions
joints.
6. Which connective tissue stores energy and cushions organs?
A. Adipose
B. Bone
C. Cartilage
D. Dense irregular
Correct Answer: A
Rationale: Adipose tissue stores fat and provides mechanical
protection.
7. Which epithelial tissue lines the air sacs of the lungs?
A. Simple squamous
B. Stratified squamous
C. Simple cuboidal
D. Pseudostratified columnar
Correct Answer: A
Rationale: Thin squamous cells allow gas exchange.
8. Which epithelial tissue is found in the trachea and has cilia?
A. Pseudostratified columnar
B. Simple cuboidal
C. Stratified squamous
D. Simple columnar
, Correct Answer: A
Rationale: Cilia move mucus and trapped particles out of the
respiratory tract.
9. Which connective tissue resists tension in one direction and
forms tendons?
A. Dense regular
B. Dense irregular
C. Areolar
D. Cartilage
Correct Answer: A
Rationale: Collagen fibers in parallel provide tensile strength.
10. Which connective tissue resists tension in multiple directions?
A. Dense irregular
B. Dense regular
C. Adipose
D. Cartilage
Correct Answer: A
Rationale: Irregular collagen arrangement allows multidirectional
strength.
11. Which stain colors nuclei blue-purple?
A. Hematoxylin
B. Eosin
