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.
Answer:
The moment where the nuclear envelope forms at each pole spindle dissolves chromosomes uncoil is called Telophase.
Explanation:
In the eukaryotic cell, telophase is the final stage in meiosis and mitosis. In this step, the effects of prophase and prometaphase are reversed. This is the forth stage and a nuclear envelope forms at each pole. The spindle dissolves and the chromosomes uncoil, cytokinesis begins. The cell continues to enlogate.
Increase in temperature decreases the Activation energy thus, increasing the rate of reaction

Answer:An open system exchanges matter and energy with its surroundings (for example, an ecosystem). ... Strictly, closed systems do not occur naturally on Earth, but all the global cycles of matter, for example,the water and nitrogen cycles, approximate to closed systems.Sep 18, 2020
