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.

No, it does not affect the work of health scientists.
The maximum weight of an animal that a technician should be able to lift on his or her own would be between 25-35 kilograms. This are standarized numbers which depend on the person/country in question. Some have stricter standards, while others have more loose standards.
Answer:
1. spontaneously
2. resting potential
3. action potentials
4. pacemaker potentials
5. K+
6. Na+
7. into
8. Ca+
Explanation:
Pacemaker cells (also known as sinoatrial node cells) are cells that generate rhythmic impulses and set the pace for blood pumping in the heart. These cells have the ability to rhythmically depolarize and initiate action potentials. In pacemaker cells, Ca2+ and Na+ levels are higher in the extracellular environment, while K+ concentration is higher intracellularly. The pacemaker action potentials have three phases: 1-depolarization, where membrane potential reaches -40 mV and voltage-gated Ca2+ channels open, 2-repolarization, where voltage-gated Ca2+ channels close and voltage-gated K+ channels open, and finally 3-gradual depolarization, which is caused by the slow influx of Na+ ions.
I think A. When a person dies at home blood circulation can't be maintained to the organs that's what happened to my dad
