between eukaryotes and prokaryotes is that eukaryotes:
a. all of these answers are correct
b. are smaller in size

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
D) potassium shifts out of the mitochondria, which destroys the infrastructure - CORRECT
ANSWER - Ans: B- influx of calcium ions halts adenosine triphosphate (ATP) production

following is function of Golgi?
a. Packages protein for secretion to the outside of the cell
b. Produces ATP for cell function
c. Contains hydrolytic enzymes
d. Is the site of protein synthesis in a cell
Which statement is a description of one of the characteristics of apoptosis?
A) apoptosis involves programmed cell death of scattered singel cells
B) apoptosis is characterized by the swelling of the nucleus and the cytoplasm
C) apoptosis involves unpredictable patterns of cell death
D) apoptosis results in benign malignancies - CORRECT ANSWER - Ans: A- apoptosis involves
programmed cell death of scattered singel cells
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 - CORRECT
ANSWER - Ans: C- the osmotic pressure is increased, which pulls additional sodium across the
cell membrane
Is the site of protein synthesis in a cell - CORRECT ANSWER - Which of the following is function
of the rough endoplasmic reticulum?
a. Contains hydrolytic enzymes
b. Is the site of protein synthesis in a cell
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:
A) adipose cells contain little water because fat is water repelling
B) the metabolic rates of obese adults are slower than those of lean 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 - CORRECT ANSWER -
Ans: A- adipose cells contain little water because fat is water repelling
Epigenetic modifications - CORRECT ANSWER - What genetic process is likely responsible for
the occurrence of asthma in only one of a pair of identical twins?
a. genomic imprinting
b. epigenetic modifications
c. methylation
d. transgenerational inheritance
RNA is synthesized from a DNA template - CORRECT ANSWER - Transcription is best defined
as a process by which
a. A base pair substitution results in a mutation of the amino acid sequence
b. DNA polymerase binds to the promoter site on RNA.
c. RNA directs the synthesis of ribosomes for protein synthesis
, d. RNA is synthesized from a DNA template
nondisjunction error - CORRECT ANSWER - What is the most common cause of Down
syndrome?
a. paternal translocation
b. paternal viral illness
c. nondisjunction error
d. maternal viral illness
klinefelter - CORRECT ANSWER - A person with XXXY has the genetic disorder called
__________ syndrome.
a. down
b. fragile x
c. klinefelter
d. turner
autosomal recessive - CORRECT ANSWER - Cystic fibrosis is caused by an
__________________ gene.
a. x-linked dominant
b. autosomal recessive
c. autosomal dominant
d. x-linked recessive
What causes the clinical manifestations of confusion, convulsions, cerebral hemorrhage, and coma in
hypernatremia?
A) high sodium in the blood vessels pulls water out of the brain cells into the blood vessels, causing brain
cells to shrink
B) high sodium in the brain cells pulls water out of the blood vessels into the brain cells, causing them to
swell
C) high sodium in the blood vessels pulls potassium out of the brain cells, which slows the synapses in
the brain
