Answer:

It allowed us to put a formation date on some geologic crossections

Explanation:

Absolute dating is a newer way of evaluating the chronology of historical events by assigning numerical ages to them. The age thus assigned might not be the exact age but it is still closer to the real age.

It is unlike relative dating techniques which simply give the chronology or order of past events instead of the exact dates. Relative dating techniques have been in use before the emergence of absolute dating techniques in the twentieth century.

Chargaff's Rule. If there is 20% Adenine in the cell, what is the percentage of Thymine, Guanine, and Cytosine found in the same
Ulleksa [173]

Answer:

A= 20%

G= 30%

T= 20%

C= 30%

Explanation:

Recall that the sum of all nitrogenous bases in the DNA nucleotide is equal to 100%. And specific base pairings of Adenine to Thymine (A=T), and Cytosine to Guanine (C=G) must be equal.

So, the percentage of Adenine equal thymine, and that of cytosine equals guanine.

Now, A + T + C + G = 100%

So, if Adenine makes up 20% of the DNA nucleotides, Thymine is also 20%.

Then, 20% + 20% + C + G = 100%

40% + C + G = 100%

C + G = 100% - 40% = 60%

So, divide 60% by 2 to obtain the individual percentage of cytosine and guanine. Each will take 30%

Finally, A= 20%; G= 30%; T= 20%; C= 30%

katen-ka-za [31]

Answer:

Increased global temperatures, leading to a 20% reduction in rainfall

Explanation:

According to this question, forest fires are becoming rampant in tropical rainforests. Although this occurrence is natural, tropical rainforests do not typically undergo this natural process due to the average yearly amount of rainfall. This means that the high amount of rainfall in tropical rainforests help prevent or reduce the high cases of forest fire incidence.

However, the recent increased occurrence of tropical rainforest fires is most likely attributed to an INCREASE IN GLOBAL TEMPERATURES, LEADING TO A 20% REDUCTION IN RAINFALL. This is because an increase in the global atmospheric temperature causes the reduction of the amount of rainfall, which naturally helps curb the occurrence of forest fires.
