Hypertrophy can occur under normal and pathological conditions. True or False
Exam 1 - (Answer) -True
Which are true of the mitochondria? Select all that apply
Exam 1
1) It is involved in cellular respiration
2) They are found far from the site of energy consumption
3) They play a role in apoptosis

Exam 1
1) Controls the transport of materials from the outside fluids to within
2 )The main structural component is made of proteins
3) Helps with the conduction of electrical currents in nerve and muscle cells
4) Aids in the regulation of cell growth and proliferation - (Answer) -Controls the
transport of materials from the outside fluids to within

Compare and contrast the two types of gangrenous necrosis
Exam 1 - (Answer) -Dry gangrene occurs when blood supply is slowly reduced to an
area. The area is dehydrated and becomes dark or black in color. Commonly seen in

swollen, with no pulse. This can occur from trauma. Bacteria is involved and is very
painful. It has the appearance of pus, because it looks wet. There is also a foul smell
Cell proliferation is the process in which proliferating cells become more specialized
cell types. True or False
Exam 2 - (Answer) -False Answer: cell differentiation
Cell differentiation is the process of increasing cell numbers by mitotic cell division.
True or False
Exam 2 - (Answer) -False, Answer: cell proliferation
What are two important properties that stem cells possess
Exam 2 - (Answer) -Potency and self-renewal
