katrin [286]2 years ago

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>

tekilochka [14]

Answer:

Trunk flexor endurance test.

Explanation:

McGill’s torso muscular test is generally used to assess the muscle endurance of the torso muscles that works as a stabilizer. This test generally includes the four major test.

The test that includes the trunk flexor of the endurance test is a timed test that involves the static isometric contraction of the muscles. This test stabilizes the spine til the individual cannot hold the assumed position and the individual exhibits the fatigue.

Thus, the correct answer is option (A).
