◉ Contain organelles and complex internal membranes. Answer: The
difference between eukaryotes and prokaryotes is that eukaryotes:
a. all of these answers are correct
b. are smaller in size
,c. contain organelles
d. have no nuclear membrane
◉ What is a consequence of plasma membrane damage to the
mitochondria?
A) enzymatic digestion halts deoxyribonucleic acid (DNA) synthese
B) influx of calcium ions halts adenosine triphosphate (ATP) production
C) edema from an influx in sodium causes a reduction in ATP production

apoptosis?
,A) apoptosis involves programmed cell death of scattered singel cells
B) apoptosis is characterized by the swelling of the nucleus and the
cytoplasm

◉ During cell injury caused by hypoxia, sodium and water move into
the cell because:
A) during cell injury cause by hypoxia, sodium and water move into the
cell because:
B) the pump that transports sodium out of the cell cannot function
because of a decrease in adenosine triphosphate (ATP) levels
C) the osmotic pressure is increased, which pulls additional sodium
across the cell membrane
D) oxygen is not available to bind with sodium to maintain it outside of
the cell. Answer: Ans: C- the osmotic pressure is increased, which pulls
additional sodium across the cell membrane

, c. Packages protein for secretion to the outside of the cell
d. Produces ATP for cell function
◉ Obesity creates a greater risk for dehydration in people because:

adults
C) the rates of urine output of obese adults are higher than thos of lean
adults
D) the thirst receptors of the hypothalamus do not function effectively.
Answer: Ans: A- adipose cells contain little water because fat is water
repelling
