BIOLOGY, A HUMAN APPROACH ULTIMATE BUNDLE
UPDATED ACTUAL EXAM QUESTIONS AND CORRECT
ANSWERS
Question 1.
Contractile ring composition
ANSWER
Belt-like protein structure formed inside the cell beneath the membrane.
Question 2.
Neuroanatomy
ANSWER
The study of how the nervous system functions.
Question 3.
Nervous Tissue Cell Classification
ANSWER
Classified into Neurons (conducting impulse cells) and Neuroglia (supporting non-conducting
cells).
Question 4.
Primary track system for intracellular motor protein movement
ANSWER
Microtubules serve as physical tracks for motor proteins across the cell.
Question 5.
Endosome
ANSWER
Membrane-bound compartment that sorts materials internalized via endocytosis.
,Question 6.
Adipose CT Structure
ANSWER
Densely packed unilocular adipocytes (distended polygonal cells with eccentric nuclei and lipid-
filled cytoplasm).
Question 7.
Disintegration of mitotic spindle
ANSWER
Occurs during telophase as nuclear membranes reform around separated chromosomes.
Question 8.
Integumentary System
ANSWER
The skin and hair.
Question 9.
Reproducibility
ANSWER
Ability to repeat an experiment and get similar results.

Types of Pseudostratified Epithelia
ANSWER
Columnar and Ciliated.

Nuclear envelope
ANSWER
Double membrane barrier enclosing the nucleus with nuclear pores for selective transport.
,Question 12.
Epithelia Classification
ANSWER
Divided into Simple (one cell thick) and Compound (many cells thick).
Question 13.
Cholesterol
ANSWER
Lipid embedded in the bilayer that regulates membrane fluidity and stability.
