Pick b just pick b I know its right I have hade the same one
Explanation:
The DNA contains many regulatory sequences that are very important, even though they do not code for proteins.
For example, the expression of every gene is regulated by a region called the Promoter. The promoter sequence, located close by the coding region of the gene, usually binds the RNA polymerase (the enzyme that transcribes genes into mRNA) as well as other proteins necessary for transcription,
The promoter sequence, thus, does not itself code for proteins, but is essential for transcription and must be highly conserved so that the RNA polymerase can find it.
The fructose 1-phosphate pathway can deplete intracellular phosphate/ ATP.
Explanation:
Fructose 1-phosphate is a derivative of fructose. For understanding in better way fructose metabolism has three enzymes. Fructose- bisphosphate aldolase B, fructokinase and Adenosine triphosphate. These all are present in liver and kidney of human as well rat. In liver rapidly fructose is change to fructose 1 through fructokinase.
After it is converted into trioses dihydroxyacetone phosphate as well as glyceraldehyde through aldolase. With glucose metabolism Fructose get synergistic effect
Answer:
Sulfur; nitrogen.
Explanation:
Acid precipitation results when sulfur and nitrogen compounds react with water in the atmosphere.
This acid precipitation is also known as acid rain and it is typically caused by the chemical reaction between sulfur oxide and nitrogen oxide which are released into the air as a result of burning fossil fuels, with water and other chemical elements present in the atmosphere.
Generally, acid precipitation (acid rain) usually have a pH of about 5.1 or below and as such, it is very acidic nature i.e possessing a large amount of hydrogen ions.
Hence, acid precipitation (acid rain) when washed to the earth has negative or harmful effects on various living and non-living organisms such as animals, plants, cars, buildings etc.
D) A & B
it protects the seed against any damage or harmful weather conditions and also helps in dispersal of the seed through different means.
