Which of these is a common component of air pollution? a. sulfur dioxide b. nitrogen c. insecticides d. herbicides

The correct answer is option A. sulfur dioxide.

Explanation:

Air pollution is excessive quantities of substances harmful including gases, particles, dust, pollen, and biological molecules in Earth's atmosphere.

Sulfur dioxide is a common air pollutant it causes many harmful reactions to the environment. It easily reacts with many components and forms of toxic products. combines with air and water, creates sulfuric acid, which is the major component of acid rain.  

Thus, the correct answer is option A.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
