Answer:
Acid rain refers to the rain which acidic in nature having a form of precipitation and elevated levels of hydrogen ions (low pH). The normal pH of rain is around 5.6
Rising concentration of Sulfur dioxide (SO2) and nitrogen oxides (NOx) in atmosphere is one of the cause of acid rain. Sulfur dioxide (SO2) and nitrogen oxides (NOx) are released by vehicles, fossil-fuel power plants and oil refineries.
When a sulfur dioxide and nitrogen oxides released in air they mix with oxygen, water and other chemicals in the air and form sulfuric and nitric acids. sulfuric and nitric acids mix with precipitation and its pH level is about 5.2 or below.
Hence, rising concentration of SO2 And NO2x is one of the biggest reason of acid which damages agriculture, buildings and wildlife et-cetra.
It is true that growing plants with cuttings can be done from the stem, root, or leaves of certain plants.
I think the diameter of it is 0.03
Answer: Option A.
Sympatric speciation
Explanation:
Sympatric speciation is a reproductive isolation or evolution of groups of species from the main population in the same geographical location.
The fruit flies changes their host plant to another due to specific characteristics posses by the choice host plant. It is a sympatric speciation because they occur in the same geographical location.
