Answer:
With respect to the composition of DNA, in an analysis it can be found that the proportions of nucleotides are A + C = G + T (option a).
Explanation:
The proportion of nucleotides in a DNA molecule can be established according to the sequence of these nucleotides on both complementary strands, since the purinic bases of one strand are complemented by the pyrimidinic bases of another:
- <em>Adenine is complemented with Thymine A=T</em>
- <em>Guanine is complemented with Cytosine G=C</em>
From this we can deduce that in a DNA molecule with two chains there will be the same amount of adenine and thymine, as well as the same number of guanine with respect to cytosine, so:
<em> A + C = G + T</em>
An example of this would be a known DNA molecule (hypothetical), with 5 molecules of Adenine and 7 molecules of Guanine. In this case there are 5 Thymines, complementary with Adenine, and 7 Cytosines like Guanine:
<em> A + C = G + T</em>
<em> 5 + 7 = 7 + 5</em>

If you still need the answer here it is! good luck
Answer:
Scientific: "does a sunflower or rose grow faster?"
Philosophy: "does leading by example help guide others?"
Explanation:
the first is scientific because you do experiments to find out the result as a fact.
the other one is philosophical cause it is more so an opinionated question but you can back it up still.
Answer:
arcic tundra
Explanation:
Tundra has two types: arctic and alpine. The coldest one is the arctic one as it is located in the northern hemisphere. Its conditions are very cruel, very cold.
The temperatures of an arctic tundra can go from 10 to 20 degrees of Farenheight in the summer. In the winter, the temperatures can go to -50 degrees. Thundra biome is one of the coldest and the biggest on Earth. It is located in the Arctic circle, mostly.
