According to research, exposure to a certain type of bacteria called mycobacterium vaccae which is found in soil can help increase serotonin levels in the body. Serotonin is a chemical found in the brain. It can boost a person's mood and decrease anxiety. This same chemical can help people better process information in their brains. Just by being outside, our bodies can breathe in this bacteria. Research has shown that this bacteria appeared to boost the mood in laboratory mice. Additionally, the mice that were given this bacteria in their diet were able to move through a maze twice as quickly as mice that were not given this . These same mice also behaved less anxiously than the other mice.

Based on information from the passage, the reader can tell that

A.  

serotonin in a person's body can help improve that person's ability to learn.

B.  

people who have less exposure to mycobacterium vaccae are often smarter.

C.  

many nutritional companies will start placing mycobacterium vaccae in food.

D.  

the laboratory tests on mice do not impact the effect of the bacteria on humans.

Step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier
