BIO202 EXAM SCRIPT 2025 QUESTIONS WITH ANSWERS
RATED A+
✔✔What feature of fishes does class chondricthyes lack? - ✔✔Neutral buoyancy (swim
bladder)
✔✔Vasal dilation - ✔✔releasing heat by widening blood vessels to allow more blood
flow to skin
✔✔Vasal constriction - ✔✔conserving heat by shrinking blood vessels to reduce blood
flow to skin
✔✔Brown fat - ✔✔Source of heat unique to neonates that is capable of greater
thermogenic activity than ordinary fat; wastes more nrg to generate heat (less efficient)
✔✔8 Essential AAs for humans - ✔✔Isoleucine, Leucine, valine, methionine,
phenylalanine, Lysine, threonine, tryptophan
✔✔Hypertrophic Cardiomyopathy (HCM) - ✔✔A condition in which the heart muscle
becomes abnormally thick to compensate for overwork.
✔✔Human average systolic/dyastolic pressure - ✔✔120/70mmhg
✔✔Two types of secretory cells in the stomach - ✔✔Parietal cells (HCl); Chief cells
(pepsinogen)
✔✔CCK hormone - ✔✔contract gallbladder, release bile into duodenum to emulsify fat
✔✔Leptin - ✔✔Hormone to decrease hunger and signal satiety
✔✔Ghrelin - ✔✔A hunger-arousing hormone secreted by an empty stomach
✔✔Interstitial fluid - ✔✔fluid in body outside cit=rculatory system
✔✔Hemolymph - ✔✔the fluid that circulates through the body of an animal that has an
open circulatory system
✔✔How many chambers are in the amphibian heart? - ✔✔3 chambers (2 atria, 1
ventricle)
✔✔How many chambers in a fish heart? - ✔✔2 chambers (1 of each type)
✔✔How many chambers in bird and mammal hearts? - ✔✔4 chambers (2 atria, 2
ventricles)
, ✔✔Systole - ✔✔when ventricles contract
✔✔Diastole - ✔✔when ventricles relax
✔✔Tidal volume - ✔✔Amount of air that moves in and out of the lungs during a normal
breath
✔✔Inspiratory reserve volume - ✔✔the maximal amount of additional air that can be
drawn into the lungs by determined effort after normal inspiration
✔✔Expiratory reserve volume - ✔✔
✔✔Vital capcity - ✔✔TV+IRV+ERV
✔✔Graded potential - ✔✔a shift in the electrical charge in a tiny area of a neuron,
proportional to magnitude of the stimulus
✔✔Tracheae - ✔✔tiny tubes in insect body that deliver oxygen directly to metabolizing
tissues
✔✔Spiracles - ✔✔breathing tubes of insects located on abdomen
✔✔operculum - ✔✔In aquatic osteichthyans, a protective bony flap that covers and
protects the gills.
✔✔Afferent - ✔✔conveying toward a center
✔✔Efferent - ✔✔conveying away from the center
✔✔Smokers cough - ✔✔occurs when cilia no longer function, excess mucus is
produced, and mucus must be coughed up
✔✔Respiratory distress syndrome - ✔✔respiratory complication in preemies because
thay cannot produce surfactant (lipoprotein that makes easier for lungs to inflate)
✔✔Astrocytes - ✔✔form blood brain barrier
✔✔Tripartile synapse - ✔✔the functional integration and physical proximity of: The
presynaptic membrane, Postsynaptic membrane, and their intimate association with
surrounding glia.
✔✔ Glucagon - ✔✔a hormone that stimulates the liver to break down glycogen
