<span>The juxtaglomerular cells near each kidney are stimulated to secrete the enzyme renin into the blood. Renin circulates throughout the body and converts angiotensinogen, made in the liver, into angiotensin I. In the lungs, angiotensin I is converted by hydrolysis to angiotensin II. Angiotensin II acts on the adrenal cortex to stimulate production of aldosterone. Aldosterone acts on the juxtaglomerular cells to increase sodium and water retention and to stimulate or depress further renin secretion, completing the feedback system that automatically readjusts homeostasis.</span>

An organism's genome is analyzed and found to contain 18% guanine. What percentage of that organism's DNA is adenine?
Oxana [17]

Answer:

32%

Explanation:

According to Chargaff in his complementary base pairing rule, he stated that the proportion of purine and pyrimidine bases is equal to 100%

That is, A + T + G + C = 100%

Where A=T and G=C i.e the proportion of each base pair is equal.

Hence, if the Guanine content is 18%, it means the Cytosine content of that DNA molecule must also be 18%. Therefore:

18 + 18 + A + T = 100

A + T = 100 - 36

A + T = 64

If the sum proportion of Adenine and Thymine is 64% and each must contain equal proportions, A or T = 64/2 = 32

Hence, Adenine contains 32%, likewise Thymine.

svet-max [94.6K]

Answer: (c) seed type

Explanation:

An independent variable is the one which can be altered or manually manipulated in an experiment. The effect of such manipulation can be examined on the dependent variable of the experiment. The dependent variable cannot be manipulated in an experiment instead it is the outcome of the experiment.

The seed type is the correct answer because the seed type can vary and the effect of which can be examined on the seed germination process and rate of seed germination.
