What teratogen is associated with increased risk for ADHD, SIDS, oral clefts, and respiratory infections in infants?

Explanation:

A teratogen can be defined as the any chemical substance which is can cause harm in the body or brain of the fetus.

The nicotine and smoking are dome of the teratogens which increases the risk of low birth, ADHD, respiratory infections and SIDS.

Taking such substance during the time of pregnancy can increase the chances of disease in the baby.

A pregnant lady should not be in direct contact with certain chemicals that are teratogenic in nature.

due to the fact that it skipped a generation we can tell it is definitely not a dominant trait, therefore it must be recessive. i think this is right let me know!

explanation:

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
