The answer is D, because carbon footprint is defined by the amount of carbon dioxide released into the air by human activities.
Answer:
Fingerprints are still the most cost-effective and reliable way to identify people: ... No two fingerprints have ever been identical in the many millions of comparisons. Fingerprints solve ten times more unknown-suspect cases than DNA fingerprinting.
Explanation:
The correct answer for the question that is being presented above is this one: "6H2O, NADP, light energy, 18ADP + Pi." The input of the light-dependent reactions, labeled X is that <span>6H2O, NADP, light energy, 18ADP + Pi.</span>
Carbon does have 4 bonds, which makes it pretty universal.
Answer:
8%
Explanation:
DNA is a double-stranded molecule made up of nucleotides: A, T, G, and C. According to Chargaff, A + T + G + C = 100%, where Adenine (A) pairs with Thymine (T) while Guanine (G) pairs with Cytosine (C).
Since G pairs with C and A with T, there must be equal proportions of each nuceleotide pair i.e. A=T, G=C
If C= 42%, G is also 42%
We then have, 42 + 42 + A + T = 100
84 + A + T = 100
A + T = 100 - 84
A + T = 16%
If A and T is collectively 16% and each must contain equal proportion, therefore, A=T = 16/2 = 8%.
Hence, proportion of Adenine and Thymine in that DNA is 8%.
