BIOL 240a Lab Practical 1 (Week 1-
Week3) Final Exam Questions and All
Correct Answers 2025-2026 Updated.
anatomy - Answer study of the *structure* of the human body and the relative relationships
between the body parts
physiology - Answer study of normal *function* of the human body
interphase - Answer -period when cell is not dividing
-cell is performing normal activities
-cell is preparing for division
prophase - Answer the chromatin fibers change into chromosomes
metaphase - Answer microtubules align the centromeres of the chromatid pairs at the
metaphase plate
anaphase - Answer the chromatid pairs split at the centromere and move to opposite poles
of the cell; the chromatids are now separated into 2 identical sets of chromosomes
telophase - Answer two identical nuclei are formed around the identical sets of
chromosomes now in their chromatin form
cytokinesis - Answer division of a cell's cytoplasm to form two identical cells
microscope parts - Answer ocular lenses, body tubes, head, arm, nosepiece, objective
lenses, stage, mechanical stage, condenser lens, iris diaphragm, substage light, coarse
adjustment knob, fine adjustment knob, mechanical stage control knobs, base, light control,
power switch
isotonic - Answer both solution in beaker and solution in cell is equal solute concentration
hypotonic - Answer solution in beaker contains less solutes than the solution in the cell
(water rushes into the cell)
, hypertonic - Answer solution in beaker contains more solutes than the solution in the cell
(water rushes out of the cell)
epithelium characteristics - Answer -body covering and lining
-tight cell junctions
-apical (free) surface
-basement membrane
-avascular
-regeneration
simple epithelium - Answer one cell layer
stratified epithelium - Answer more than one layer
squamous epithelium - Answer flat or squashed
cuboidal epithelium - Answer cube shaped
columnar epithelium - Answer column shaped
simple cuboidal epithelium (location) - Answer kidney tubules and most endocrine glands
simple cuboidal epithelium (structure) - Answer big nuclei in the middle of the cells
simple squamous epithelium (location) - Answer kidneys, lungs, and the lining of blood
vessels
simple squamous epithelium (structure) - Answer very flat, cannot see basement membrane,
have individual nuclei
simple columnar epithelium (location) - Answer digestive tract and uterine tube
simple columnar epithelium (structure) - Answer can be ciliated and non-ciliated, nuclei tend
to be near the basement membrane, may have goblet cells
pseudostratified columnar epithelium (location) - Answer trachea
