Select one:
4.50 points out 4.50 points out pneumonia?
bicuspid or mitral valve.
of 4.50 of 4.50
tricuspid valve. Select one:
aortic semilunar valve. Because antibiotics, such as ampicillin destroy the cell walls of cardiac muscle cells.
pulmonary semilunar valve. Because antibiotics, such as ampicillin cause the cells lining blood vessels to endocytose bacteria
and deposit them in cardiac muscle tissue.
coronary sinus valve.
Because antibiotics, such as ampicillin are not effective in the treatment of bacterial pneumonia.
Because antibiotics, such as ampicillin destroy the cell walls of bacteria which cause a toxin to be
released that will destroy cardiac muscle cells.
The correct answer is: bicuspid or mitral valve.
The correct answer is: Because antibiotics, such as ampicillin destroy the cell walls
of bacteria which cause a toxin to be released that will destroy cardiac muscle
cells.
