APHY 101 Module 8 - Midterm Exam (Ch. 1-6)
A body has been sectioned in such a way that there is one whole lung per section and the
urinary bladder has been split in half. What type of section is this?
A. frontal
B. coronal
C. transverse
D. sagittal - ANS-D. sagittal
A burn affecting only the epidermis is a
A. deep partial-thickness burn
B. superficial partial-thickness burn
C. second-degree burn
D. third-degree burn - ANS-B. superficial partial-thickness burn
A cell is surrounded by an extremely thin, flexible membrane. Why is the membrane selectively
permeable?
A. it allows all organic substances to pass through, but excludes all inorganic substances that
could be harmful
B. it allows someone substances to pass through and excludes others based on size, polarity,
and other factors
C. it does not allow any substances to pass through as they could damage the cell
D. it allows all substances to pass through, making it easier to absorb nutrients. - ANS-B. it
allows someone substances to pass through and excludes others based on size, polarity, and
other factors
A complete atom is electrically neutral because
A. the number of electrons is greater than the number of protons
B. the number of electrons equals the number of neutrons
C. the number of protons equals the number of neutrons
D. the number of electrons equals the number of protons - ANS-D. the number of electrons
equals the number or protons
A hypotonic solution
A. has a lower concentration (number) of impermeant solute than do the cells in the solution
B. causes cells to shrink
, C. has a higher osmotic pressure than do the cells in the solution
D. would cause cells in the solution to lose water - ANS-A. has a lower concentration (number)
of impermeant solute than do the cells in the solution
A mutation can cause disease if
A. the DNA sequence does not change
B. it attracts mutagens
C. the DNA sequence changes so that one amino acid is substituted for another in a way that
does not alter the encoded protein's functioning
D. the DNA sequence changes so that one amino acid is substituted for another in a way that
affects the encoded protein's functioning - ANS-D. the DNA sequence changes so that one
amino acid is substituted for another in a way that affects the encoded protein's functioning
A peptide bond forms between
A. adjacent amino acids
B. a tRNA and an mRNA
C. a gene and a protein
D. an mRNA and an rRNA - ANS-A. adjacent amino acids
A person has alkalosis if the blood pH
A. is below 7.0.
B. rises above 7.5.
C. drops below 7.3.
D. is above 7.0. - ANS-B. rises above 7.5.
An isotonic solution
A. has the same osmotic pressure as the cells in the solution
B. has more water entering than leaving a cell
C. has a greater concentration of impermeant solute than a cell
D. causes a cell to shrink - ANS-A. has the same osmotic pressure as the cells in the solution.
Anatomy and physiology are difficult to separate because
A. physiological functions in an organism are ongoing.
B. our understanding of physiology is changing more than our understanding of anatomy
C. body parts take up space
D. physiological functions depend on anatomical structures - ANS-D. physiological functions
depend on anatomical structures
As cells are pushed from the deeper portion of the epidermis toward the surface,
