Answer:
Thymine= 60 ng
Guanine= 20 ng
The complementary base pairing occurs between adenine and thymine and guanine and cytosine bases.
Explanation:
According to the Chargaff rule, a double-helical DNA molecule has an equal number or equal amount of adenine and thymine bases since adenine always pairs with thymine. Similarly, the amount of guanine base is equal to that of the cytosine base.
Chargaff rule is based on the complementary base pairing between purine and pyrimidine bases. According to the given information, the amount of adenine is 60 ng. Therefore, the cell would have 60 ng thymine. Similarly, the amount of the cytosine base in the cell is 20 ng which means that the cell would have 20 ng of guanine base.
I am not entirely sure what you mean by "responding variable" but I'm going to guess it was the vinegar since it has been used as a perservative for years.
Hope that helps in some way.
The correct answer is B. The temperature of the water decreased by 5°C
Explanation:
Temperature and the changes in it are part of quantitative observations because these can only be measured and understood through numbers. Indeed, the temperature is globally measured through different numerical scales such as the Celsius or the Kelvin scale. This does not occur in other qualities such as color because this is considered and analyzing using qualities or traits rather than values. According to this, the correct answer is "The temperature of the water decreased by 5°C."
