One of the human health effects of sulfur dioxide is:
a. carboxyhemoglobin formation
b. bronchoconstriction
c. lung cancer
d. brain/cns damage

Bronchoconstriction

Explanation:

Bronchoconstriction may be defined as the medical condition in which the airways of the lungs get constricted because of hardening of smooth muscle. The symptoms included are wheezing, coughing and breath shortness.

The main cause of bronchoconstriction is the effect of inhalation of sulfur dioxide in the lungs. The sulfur dioxide causes the hardening of smooth muscle of the lungs and may also effect the eyes.

Thus, the correct answer is option (b).

corona the outer atmosphere of the sun, temp. may reach 2,000,000 c

chromosphere middle layer of the sun's atmosphere

photosphere visible surface of the sun

convection zone layer of the sun which energy travels by convection from the radiative zone to the photosphere

radiative zone layer of the sun which energy is transferred away from the core by radiation

core very dense center of the sun

nuclear fusion process by which tow or more low-mass atomic nuclei fuse to form another, heavier nucleus.

radiation when energy is transferred as electromagnetic waves

convection the process in which heat is transferred by the circulation or movement of matter

differential rotation the way the sun rotates, rotating faster at its equator than at higher latitudes

sunspots dark areas that form on the surface of the sun

solar flare an explosive release of energy that can extend outward

prominences huge loops of cool gas that extend outward from the photosphere

one of the most common forms of pain or discomfort we feel during strenuous exercise is a burning sensation in our lungs or muscles that goes away shortly after we cease the activity. this is caused by a build-up of lactic acid.
