Mostly his or hers sleep.
Answer:
ALCOHOL.
Explanation:
A teratogen is any agent that causes abnormalities when a developing baby is exposed to it during the mother's pregnancy. They include toxic chemicals, radiation, viruses, alcohol, smoking, certain prescription drugs and other agents.
Exposed of a fetus to alcohol (especially a lot or over a long period of the pregnancy) causes fetal alcohol spectrum disorders (FASD) or fetal alcohol syndrome (FAS). Fetal alcohol syndrome is marked by a pattern of birth defects including: Small head and body size, specific abnormal facial features, learning and behavioral problems.
Since Jamie's child's abnormalities can be traced to teratogen, therefore, the teratogen agent she was most likely abusing was ALCOHOL.
One can reduce the risk of Environmental tobacco smoke(ETS) by visiting places that are smoke-free.
Environmental tobacco smoke (ETS), or second-hand smoke, is the air polluted by tobacco smoke.
ETS consists of mainstream smoke (smoke exhaled from the smoker's lungs) and side stream smoke (smoke from the lit end of a cigarette, pipe, or cigar).
Conventional smoke exhaled by the smoker has a lower concentration of carcinogens, nicotine and tar. For this reason, side-stream smoke is more dangerous than mainstream smoke. ETS from tobacco, cigars, and pipes contain over 4,000 chemical compounds.
Over 50 of these chemicals are carcinogens. Several studies have shown that infants exposed to ETS are more likely to develop asthma than their unexposed peers. Inhaling ETS poses a serious health hazard.
Health Risks for Non-smokers
Second-hand smoke kills about 3,000 people each year from lung cancer. ETS causes eye irritation, headaches, ear infections, and coughing in people of all ages. It aggravates asthma and other respiratory disorders and increases the risk of coronary artery disease.
