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>
I believe the first answer is #4 and the second is #1. Please correct me if I am wrong.
Hello there!
Usually, the procedures you should follow is using hand sanitizer or just washing your hands. That can help remove some microbes, but it is inevitable to not get any germs on you
^Hope it helps
Right when there is not that a lot of water within the body, pituitary organ releases additional vasoconstrictor to resorb more water in the circulatory framework therefore the pee are targeted..but once there is additional water in body, less ADH can be discharged to resorb less water within the blood therefore it leads to a weaken pee.
So the answer you are looking for is B. <span>It prompts the kidneys to reabsorb more water into the bloodstream to dilute the salts.
I hope this helps!</span>
