Question

why do some physicians advise patients with a bladder infection to drink a lot of cranberry juice?
cranberry juice makes the urine more acidic, decreasing the rate at which microorganisms can grow and reproduce.

all of the above are correct.
topic: sec. 9.4
skill: application
cranberry juice increases the efficiency of urine production by the kidneys.

Explanation:

Cranberry juice contains compounds that can make urine more acidic. This acidic environment is less favorable for the growth and reproduction of microorganisms that cause bladder - infections. It does not directly cause bacterial cells to burst by increased fluid volume, nor does it contain chemicals that directly kill viruses and bacteria in the way antibiotics do, and it has no significant effect on kidney urine - production efficiency in this context.

Answer:

Cranberry juice makes the urine more acidic, decreasing the rate at which microorganisms can grow and reproduce.
