Chlorine in the stratosphere is believed to come primarily from cfcs rather than from natural sources such as volcanoes because:
Andreyy89

 he answer is because <span>samples of air taken over erupting volcanoes shows that volcanoes contribute a small amount of chlorine in the stratosphere compared to CFCs. Volcanic eruptions account for a large instability of chlorine from land to the atmosphere on a yearly basis. This is in addition to chlorine that enters the atmosphere from sea spray, industrial processes and biological gases which are from CFCs. All of these inputs happen near or at the base of the atmosphere. Very little of the material emitted from volcanoes makes it up into the upper reaches of our atmosphere which is the stratosphere where it could touch the ozone layer. However, most of it is believed to be deposited lower down which is in the troposphere, where it then rained out back to the surface of the earth.</span>

Fill in the table below by writing the complementary strand of DNA that would be formed by each template strand
BlackZzzverrR [31]

Answer:

DNA strand = complementary strand

GCAAG = CGTTC

TTACG = AATGC

GATAC = CTATG

CGGAT = GCCTA

DNA strand = mRNA strand

CGATT = GCUAA

GCTTA = CGAAU

GCATC = CGUAG

TTCAT = AAGUA

Explanation: A complementary strand is not the same in base composition and sequence with the template strand. In DNA, anywhere adenine is found in the template strand, thymine is found in the complementary strand and anywhere cytosine is found in the template strand, guanine is found in the complementary strand. But in RNA, anywhere adenine occurs in the DNA template strand, uracil occurs in the mRNA strand, wherever thymine occurs in the DNA template strand, adenine occurs in the mRNA strand and wherever guanine occurs in the DNA template strand, cytosine occurs in the mRNA strand.

Summarily, in DNA adenine pairs with thymine while cytosine pairs with guanine while in mRNA, adenine pairs with uracil, while cytosine pairs with guanine.
