The human body has more than 600 muscles. :)
If she deposits $1200 and it earns an interest of $144 over 2 years, then she earns $72 per year. Meaning that after 7 years her account will have a balance of $1704
$1344 - $1200 = 144
144/2 = 72
72 * 7 = 504
$1200 + $504 = $1704
Preventive medicines that contain antibodies are called a) vaccines.
Vaccines are an important and integral part of our society. And before I say anything further. Vaccines DO NOT cause autism or any other similar disorder. There is no evidence for this claim. In any case, when we're injected with vaccines we're given doses of antibodies so that our bodies would be prepared (in the case of a potential outbreak of a certain disease) for that disease. Because we have already seen the same particles in our vaccine, our body will know how to react in a proper and efficient way when it sees it in a "disease-like" form :)
