There are more than 7,000 harmful chemicals in tobacco smoke, at least 250 are known to be harmful. Some of these chemicals are:
Nicotine
Formaldehyde
Lead
Arsenic
Ammonia
Radioactive elements such as Polonium-210
Benzene
How some of those chemicals affect the body:
Nicotine is highly addictive and can cause an increase in blood pressure, heart rate, flow of blood to the heart and a narrowing of the arteries (vessels that carry blood).
Symptoms for formaldehyde are watery eyes; burning sensations in the eyes, nose, and throat; coughing; wheezing; nausea; and skin irritation
High levels of lead may cause anemia, weakness, and kidney and brain damage. Very high lead exposure can cause death.
Arsenic poisoning occurs over a brief period of time, symptoms may include vomiting, abdominal pain, encephalopathy, and watery diarrhea that contains blood. Long-term exposure can result in thickening of the skin, darker skin, abdominal pain, diarrhea, heart disease, numbness, and cancer.
High concentrations of ammonia in air causes immediate burning of the eyes, nose, throat and respiratory tract and can result in blindness, lung damage or death.
Cloud seeding
Another instance where supercooled and mixed-phase clouds are studied extensively is related to cloud seeding and weather modification. Cloud seeding involves the addition of aerosol, such as silver iodide aerosol, that modifies the phase and size distribution of hydrometeors. The goal of cloud seeding is to alter the natural development of the cloud to enhance precipitation, suppress hail, dissipate fog, or reduce lightning. Various cloud seeding techniques are employed, as particles are released from rockets, aircraft, or ground. The seeding of ice-phase clouds can induce the phase transition from a supercooled water cloud to one composed of ice. In the case of dynamic cloud seeding, the purpose is to stimulate vertical air motions through increased buoyancy caused by the release of latent heat of freezing (Hobbs, 1975; Cotton and Pielke, 1995).

Answer:
The sun is located at one of the two foci in the shape of Earth's orbital path
Explanation:
The answer to fill up the blank is foci.
Answer:
1) Basilar membrane
2) Stereocilia or hair cells
3) Nerve cells
4) Auditory
5) Temporal lobe
Explanation:
Basilar membrane: located inside of the cochlea which is located in the inner ear. This membrane separates two tubes that is filled with liquid which is also important for hearing.
Hair cells: Connected to the basilar membrane and they acts as sensory receptors which can catch movements (ripples) in the basilar membrane and pass this message to the neurons.
Nerve cells: One of the main cell types in the brain, which are responsible for signal transfer.
Auditory cortex: This part of the brain is located in temporal lobe and handles the auditory information.
