Answer: d. all the above are true.
Mining is a process of extraction of valuable minerals and geological materials like fossil fuels, ores from the sub and deeper surface of the earth crust. Country's economy is chiefly dependent upon mining as materials are economically valuable but it affects the local populations in both positive and negative sense.
Mining is a vital part of the economy of surrounding towns : The resources obtained after mining can be sold at high price and can be economically useful for towns.
It introduces pollution into local water supplies : The dust liberate after mining can pollute the nearby water body, hence local water supply will be polluted.
Disrupts local populations of flora and fauna : The mining process involves the removal of the local land form which can cause elimination, migration and extinction of population of flora and fauna species. Hence, the biodiversity of that area is lost.
Therefore, all these situations are true.
Answer: I believe that it should be the student's choice and not forced upon them, though it is important for them to get some sort of exercise to stay healthy.

A muscle consists of many muscle tissues which are bundled together and surrounded by epimysium. Epimysiuma is tough connective tissue similar to cartilage. The epimysium surrounds bundles of nerve cells that run in long fibers, called fascicles. The above is the order of the structures that are protected.
<span>"Restriction enzymes would be used to cut the DNA into smaller pieces." is the statements best describes the first thing researchers need to manipulate dna. Before manipulation it is needed to isolate the desired DNA segment. Restriction enzyme can be also called as restriction endonuclease.</span>
Answer: The correct answer is D. Adenine
Explanation:
There are two types of nucleic acid ribonucleic aid and deoxyribonucleic acid. There are four types of nucleotides which make the DNA and these are adenine, guanine, thymine, and cytosine.
Adenine and thymine make complementary base pairing with each other and guanine and cytosine make complementary base pairing with each other in DNA.
In RNA against adenine, uracil comes and against thymine adenine comes. Therefore as at location 2 thymine is present in DNA so in RNA against it adenine will come.
