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.

Answer:
D. Lactose is absorbed intact and transported through the portal vein to the liver.
Explanation:
Lactose is a disaccharide. It is a sugar composed of galactose and glucose subunits and has the molecular formula C₁₂H₂₂O₁₁. Lactose as a disaccharide can never be absorbed just like that. It needs to be broken down into monosaccharides first.
The diagnosis will be variant creutzfeldt jakob disease or as called as vCJD. The variant creutzfeldt jakob disease is an intermittent and fatal human neurodegenerative illness. The ingestion of food of bovine origin contaminated with the agent of bovine spongiform encephalopathy which is a disease of cattle and has been strongly connected to the existence of vCJD in humans.
Answer:
If you did not follow the procedure as you should have.
Explanation:
You may have to repeat an experiment for several reasons. It can be because you need to be certain of the results so that you have to perform it several times. Or you need more precise results so that you can fine-tune the variables and repeat the experiment again.
The most common scenario where an experiment would be replicated would be in a situation where you did not follow the procedure that you have outlined exactly like you should have so that the results you got are not 100% reliable. In such a case, the experiment would need to be replicated for the correct results.
I hope this answer helps.
