To complete the sentences using the correct words or phrases, you need to understand the context of how microbes, particularly those in the gut, can influence various biological processes. Here’s the breakdown:
Microbes are our behaviour.
The word that best fits in this context is "influence." Microbes influence our behavior.
Elaine Hsiao's theory is that microbes affect brain.
You should insert "the" before "brain" to make a grammatically correct sentence: Microbes affect the brain.
Microbes in your gut send messages to your ______.
The correct word to complete this sentence is "brain." Microbes in your gut send messages to your brain.
The messages travel through ______ in your body.
The suitable word here is "cells." The messages travel through cells in your body.
Elaine Hsiao did a study using ______.
The correct word is "mice." Elaine Hsiao did a study using mice.
One thing the study showed is that animals are ______ if they have microbes in their gut.
The fitting word is "quieter." One thing the study showed is that animals are quieter if they have microbes in their gut.
In summary, the study by Elaine Hsiao explores how gut microbes communicate with the brain by sending signals through cells and shows that this gut-brain axis can potentially affect behavior, using mice as a model to demonstrate her theory on the influence of microbes on behavioral outcomes.
