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.

Answer 1: The skin and the Liver are easy to repair using stem cells.
Explanation:
Method of stem cells to heal liver disorders has been demonstrated useful in most of the situations. Scientific research shows the use of stem cells in the therapy and remedy of several disorders like Liver Cirrhosis, End Stage Liver Failure, hereditary liver disorder and including the Liver tumor. The stem cells hold the capacity to regenerate and reproduce by them or stem cells hold particular properties of renewing themselves. Because of their expertise stem cells can modify into any tissue sort, they have enormous potential in several infection treatments and traumatic damages.
Answer 2: Apical meristem and the lateral.The heart, brain, bone marrow and the Lungs in adults are difficult to repair using stem cells.
Explanation:
There are two kinds of stem cells: embryonic stem cells and adult stem cells. Adults also have stem cells in the heart, brain, bone marrow, lungs, and other organs. They are our built-in replacement tools, restoring cells infected by infection, trauma and everyday erosion, and cut. Adult stem cells are extremely difficult for specialists to operate because they are extra challenging to derive and culture than their immature complements.
I think its the Chylomicrons
