true / false.

True

Explanation:

About 20 percent of all children have difficulties that could be connected to behavioral teratogens, but it is hard to link the teratogens with the difficulties because the relation is not simple or direct.

First, it has to be determined if the brain or emotional problems that the kid has are due to behavioral teratogens or not, which can be hard since there are a lot of factors that can influence teratogens and affect the baby differently.

no, because those are both different running competitions. while distance runners train their legs and their lungs to run long amounts of time, the sprinters are training their legs and their lungs to give all they have in the little amount of area they need to cover. the brain also plays a huge part in all of this.

the brain is the only thing in your body that sends messages to your body telling you to run. if you are a long distance runner and you have the mind set of a sprinter, you will not get anywhere. if you have a long distance mind set and you have to run 200m in 20 seconds then you will not make it in time.
