BIOS251 EXAM 2 CERTIFICATION EVALUATION
TEST PAPER 2026 COMPLETE STUDY
QUESTIONS WITH CORRECT ANSWERS
◉ Pinocytosis. Answer: Used to incorporate fluids or dissolved
substances into cells
EX: the microvilli of the small intestine is used to absorb nutrients
from the lumen of the gastrointestinal tract
◉ active transport. Answer: the movement of materials through a
cell membrane using energy
EX: Glucose moving in or out of a cell.
◉ simple diffusion. Answer: Diffusion that doesn't involve a direct
input of energy or assistance by carrier proteins.
EX: movement of gases across the membrane
◉ hypotonic solution. Answer: causes cell to absorb water and swell
◉ hypertonic solution. Answer: causes cell to lose water and shrivel
◉ Isotonic solution. Answer: causes no change in cell volume
, ◉ endocrine glands. Answer: -Release hormoes into the blood or
interstitial fluid
-Secretions do NOT have ducts
◉ merocrine secretion. Answer: -Secretions are released from
secretory vesicles via exocytosis at the apical surface
◉ apocrine secretion. Answer: -Secretions are released via a loss of
the apical cytoplasm
-Secretory vesicles are housed in the apical portion of the cytoplasm
-Apical cytoplasm is shed
◉ holocrine secretion. Answer: -Secretions via loss of the entire cell
-Cells increase in size as secretions occurs
-more superficial cells burst and release their cytoplasmic contents
-Stem cells that are close to the basement membrane divide and
replace lost cells
◉ eccrine secretion. Answer: most common sweat gland with vesicle
moving toward cell membrane
◉ Epithelial tissue. Answer: -Covers body and lines body cavities
