It interacts because it talks about medicine and heath
The answer to the question above is 2. The girl should receive 2 doses of influenza vaccine this flu season. Basically, influenza is contagious. This virus can spread from person-to-person. Children at this age is highly susceptible to this kind of serious illness because their immune system is not fully competent enough compared to adults. Even adults can acquire this illness if they are immunocompromised. This is the reason why children need 2 doses.
Huh do you mean like a heartbeat???
The main factor that controls the rate of breathing is..
A.) concentration of carbon dioxide.
If we think about it.. When we breath in oxygen, right away it enters your lungs and turns into carbon dioxide. Well since your lungs need to process oxygen and bring oxygen into the blood stream. Then as soon as the oxygen comes inside (inhale) the oxygen turns into carbon dioxide and you breath it out (exhale) to get a new oxygen load.
Makes sense? lol
Good Luck! :)
