BIOL 2457 - Exam 1 |Questions and Correct Detailed
Answers with Complete Solutions |100% Correct 2026
anatomical position -Correct Answer ✔-body upright, standing erect facing the
observer, head and eyes facing forward, palms turned forward
prone position -Correct Answer ✔-body is laying face down
surpine position -Correct Answer ✔-body is facing upward
cytology -Correct Answer ✔-microscopic study of the cells
histology -Correct Answer ✔-microscopic study of tissues
characteristics of life -Correct Answer ✔--organization and complexity
-metabolism
-homeostasis
-growth and development
-response to stimuli (movement)
-reproduction and differentiation
-adaptation
levels of organization (smallest to largest/complex) -Correct Answer ✔--chemical
level -> atoms
,-cellular level: molecules combine to form cells
-tissue level: groups of cells that work to perform a particular function
-organ level: tissues are joined to form organs
-system level: related organs with a common function
-organism: any organisms or living individual
anterior (ventral) -Correct Answer ✔-near the front of the body
posterior (dorsal) -Correct Answer ✔-near to the back of the body
superior (cranial) -Correct Answer ✔-toward the head
inferior -Correct Answer ✔-away from the head
proximal -Correct Answer ✔-nearer to the attachment of a liimb to the trunk
distal -Correct Answer ✔-further to the attachment of a limb to the trunk
lateral -Correct Answer ✔-away from the midline
medial (mesial) -Correct Answer ✔-nearer to the midline
feedback system -Correct Answer ✔-
, negative feedback -Correct Answer ✔--most common
-reverses a change in a controlled condition
-when a variation outside of normal limits triggers an automatic response that
corrects the situation
-ex. blood pressure, blood loss, sweating
positive feedback -Correct Answer ✔--strength or reinforce a change in one of the
body controlled conditions
-when an initial disturbance produces a response the exaggerates the disturbance
-ex. giving birth or blood loss
enzymes -Correct Answer ✔--catalysts in living cells
-high specific in terms of substrate
-speed up chemical reactions by increasing frequency of collisions, lowering
activation energy and properly orientating colliding molecules
exergonic -Correct Answer ✔--bond is broken and has more energy that is formed
-extra energy is released as heat
endergonic -Correct Answer ✔--requires atp energy to form a bond and form
proteins
activation energy -Correct Answer ✔-energy required to break chemical bonds in
the reactant molecules a reaction an start
