Answer:
Sally's digestive function would be more affected by the consumption of antibiotics due to certain vitamins might not be synthesized and foods might not break down as well.
Step-by-step explanation:
Options for this question are:
- Certain vitamins might not be synthesized and foods might not break down as well.
- Foods will not be able to be digested at all and will remain in the stomach.
- Sally's digestive function will not change because gut flora do not affect digestion.
- Sally's stomach may become bloated due to an inability to break down lactose.
The gut bacterial flora -also called intestinal microbiota- is linked to multiple metabolic and immunological functions, among others.
One of the functions of gut bacterial flora is to promote the breakdown of food into particles that can be more easily absorbed. In addition, they perform the function of synthesis of some vitamins, such as biotin, vitamins B12 and K, folic acid and pantothenic acid.
The intake of antibiotics can affect the gut bacterial flora, producing in Sally a difficulty to digest food and produce vitamins.
