The table in figure 12-3 shows the results of measuring the percentages of the four bases in the dna of several different organisms. some of the values are missing from the table. based on chargaff's rule, the percentages of guanine bases in chicken dna should be around .

a. 28.8%
b. 19.9%
c. 21.5%
d. 13.4%

Explanation:

The table for this question is attached as image

Solution -

As per  Chargaff's rule the amount of base  molecule of DNA must be equal to their complementary bases.  

For instance the amount of adenine must be equal to amount of thymine and amount of guanine must be equal to amount of cytosine and the amount of these two base is never equal to each other.

Thus, in the table if % of cytosine in chicken’s DNA is 21.5 % then the guanine % would be also 21.5%

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
