Question

Placing obese mice microbiota into germ-free (gnobiotic) mice results in:

a) Increased weight loss
b) Decreased weight loss
c) No change in weight
d) Unpredictable changes in weight

Answer 1

When the microbiota of obese mice is transplanted into germ-free (gnobiotic) mice, the result is increased weight gain.

Step-by-step explanation:

When the microbiota of obese mice is transplanted into germ-free (gnobiotic) mice, the result is increased weight gain. This was shown in a study where the microbiomes of healthy and undernourished children were transplanted into germ-free mice, and the mice with the microbiome from the undernourished child experienced reduced growth in both length and weight. Therefore, the correct answer to your question is Decreased weight gain.
