Jordan is doing a science fair project on the effects of music on the growth of tomatoes yes to tomato plants plan a.m. Plan B t

hey close in a window and gives each of them water that a is exposed to classical music is on headphones attached to the soil plan B is not exposed to any music throughout the growth period Jordan counts the number of tomatoes produced by each plant.

Answer:

Exposure to music or Music

Explanation:

The independent variable is the variable in an experiment that is changed to determine if the change will have an effect on the subject. With the title alone, "The effects of music on the growth of tomatoes", we can see tht Jordan wants to see the <u>effect of music. </u>To test this, music is changed to determine if there is any difference.

On one plant classical music is played and on the other, no music is played. So what was changed is the music or exposure to music.

If the amount of sodium in the blood increases, what would a negative feedback control mechanism be expected to do?
Crank

Answer: Decreases

Explanation:

The amount of sodium in the blood will increase as the main function of the negative feedback is to maintain the homeostasis inside the body.

If blood pressure is too high, then heart rate decreases because of this the blood vessels increases in the diameter and the kidney retains less water.

These changes will return the blood pressure to be normal. The same process gets reversed when the blood pressure decreases.

In an analysis of the nucleotide composition of DNA, which of the following proportions will be found?
katrin [286]

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>
