Answer:
Acid deposition-usually referred to simply as acid rain-actually includes two forms of pollution, wet and dry. ... In the wet type of acid deposition, these compounds combine with water vapor in the atmosphere to form highly corrosive sulfuric and nitric acids.
Explanation:
The accumulation of acids or acidic compounds on the surface of the Earth, in lakes or streams, or on objects or vegetation near the Earth's surface, as a result of their separation from the atmosphere. Acid deposition can harm the environment in a variety of ways, as by causing the acidification of lakes and streams, the leaching of minerals and other nutrients from soil, and the inhibition of nitrogen fixation and photosynthesis in plants.♦ The accumulation of acids that fall to the Earth dissolved in water is known as wet deposition. Wet deposition includes all forms of acid precipitation such as acid rain, snow, and fog.♦ The accumulation of acidic particles that settle out of the atmosphere or of acidic gases that are absorbed by plant tissues or other surfaces is known as dry deposition.
Answer:
All the arteries except pulmonary artery carry pure blood..it is so because blood flows with a high pressure and speed And because Arteries are situated deeper under the skin have thick-walled with Narrow lumen(cavity) and pulmonary artery carries deoxygenated blood i.e without oxygen..
Explanation:
lumen means Empty space within an object(solid)

The branch of biology that deals with the relations of organisms to one another and to their physical surroundings.
Answer:
A) results in evolutionary adaptation
Explanation:
Natural selection is the process in which organism with specific traits are able to survive than others. Natural selection allows the fittest to survive while eliminating the others. It prepares the species for environmental changes by resulting in evolutionary adaptation.
Evolutionary adaptation occurs when species goes through certain processes (hereditary, habits, Physical structures) to become fit in environment. These changes help the organism to evolve to adopt the changing environmental conditions.
Example; Sweating in human.
