PLTW HBS FINAL REVIEW EXAM 2025
QUESTIONS AND ANSWERS
Location on the body where routine blood is drawn from the body? - ANS Veins in the arm
A basin-shaped structure in the skeleton of many vertebrate that is formed by the pelvic girdle
together with the sacrum and often various coccygeal and caudal vertebrae and that in humans
is composed of the 2 hip bones bounding it on each side and in front while the sacrum and
coccyx complete it behind? - ANS Pelvis
Longest bone of the upper arm or forelimb extending from the shoulder to the elbow -
ANS Humerus
Differences in DNA sequences on homologous chromosomes that can result in different
patterns of restriction fragment lengths (DNA segments resulting from treatment with
restrictioned enzymes)? - ANS Restriction Fragment Lengths Polymorphisms (RFLP's)
Situated at or toward the hind part of the body - ANS Dorsal
A group of subcortical structures (as the hypothalamus, the hippocampus, and the amygdala) of
the brain that are concerned especially with emotion and motivation? - ANS Limbic System
Either of the pair of sensory nerves that compromise the 2nd pair of cranial nerves, arise from
the ventral part of the diencephalon, form an optic chiasma before passing to the eye and
spreading over the anterior surface of the retina, and conduct visual stimuli to the brain? -
ANS Optic Nerve

The horizontal plane that divides the body into a top half and bottom half? - ANS Transverse
Plane
Biometrics is? - ANS Science & technology of measuring & statistically analyzing biological
data
