Answer :
By calculating 30% of 325 g, we determine that 97.5 grams of a person's feces consist of bacteria per day. The correct answer is option a.
If an average Homo sapiens produces 325 g of feces per day, and 30% of it consists of bacteria, to find the amount of bacteria in the feces we simply calculate 30% of 325 g.
Here is the calculation:
- Calculate 30% of 325 g: (30/100) x 325 g = 0.3 x 325 g = 97.5 g
Therefore, 97.5 grams of a person's feces consist of bacteria per day. So the answer is a) 97.5 g.
