The bacterial population per ml of rumen liquor in a cow is?
OPTIONS
(A) 109
(B) 107
(C) 106

ANSWER
(A) 109
EXPLANATION
Rumen liquor contains an extremely dense microbial population, with bacteria commonly present at about 10^9 organisms per milliliter or more. Counts of 10^7, 10^6, or 10^4 per milliliter are far below the typical bacterial concentration in a normally functioning rumen.
