27. Answer is B. The normal stratified squamous epithelium develops additional layers of cells.
It does not replace the tissue with different tissue (aka metaplasia). It does not produce change in size, shape, or appearance to become abnormal cells (aka dysplasia). There is no increase is just size of cells (hypertrophy).
28. Answer is A. The cells were from an area that was not receiving adequate oxygen.
Vacuolation is a symptom of hypoxic injury which is due to low oxygen supply
29. Answer is D. Liquefactive necrosis.
Liquefactive necrosis occurs in neurons and glial cells of the brain. Not in gangrenous necrosis (muscles) coagulative necrosis (kidney, heart, adrenal glands) or caseous necrosis (lungs).
30. Answer is C. is due to apoptosis.
For example: Uterus decreases after child birth. Physiological (normal) not pathological.
