Studying things that are small is very important.  Microorganims are very ​ (a)   living things that can only be seen with a microscope. Bacteria is one kind of microorganism. 

• small
• large

Bacteria make up gut microbiomes and are found in feces.  A fecal transplant is a medical procedure where a doctor takes feces from a person with a ​ (a)   gut microbiome and puts it into the gut of person with an unhealthy microbiome.

• healthy
• unhealthy

This fills up the space in the gut, limiting the food and space for invading ​ (a)   bacteria.  

• harmful
• helpful

One piece of evidence that showed how a fecal transplant might be useful involved a study with ​ (a)  

• mice.
• rats.
• rabbits.

​ (a)   groups of mice were given the harmful bacteria called ​ (b)   .

• Two
• Three
• Four
• Salmonella
• C. difficile
• C. jejuni

One group of mice did not have a normal amount of healthy gut bacteria.  All the mice in this group became infected and very sick.  The other group of mice had a normal amount of gut bacteria.  Only a small number of mice in this group got very sick.

The mouse experiment shows that when there is (a)   healthy gut bacteria, harmful bacteria can use the extra space and food, causing infection.

Fecal transplants could provide a way to add more healthy bacteria to the gut and block the unhealthy bacteria from using the extra (a)   and food.  

• space
• heat

Another piece of evidence that shows when a ​ (a)   transplant might be helpful comes from an article titled The ​ (b)   Micobiome. 

• fecal
• heart
• lung
• Human
• Mouse
• Rat

In the article it states that the "human body provides bacteria with food and living space that it needs-that's what makes our bodies such a good environment for bacteria."  This demonstrates that our bodies are ideal places for all kinds of bacteria, including healthy and harmful bacteria.  Fecal transplants can provide a way to make sure that the ​ (a)   is home to more healthy bacteria, rather than unhealthy ones that can cause infections.
