Answer:
This experiment proved that DNA replicated semiconservatively; half the original polynucleotide is conserved in each of the two copies
Explanation:
Semi-conservative mode of replication means that the two strands of DNA unwind from each other, and each of themacts as a template for synthesis of a new, complementary strand. As a result, two formed DNA moleculesc ontain one original strand and one new strand.
Meselson and Stahl experiment showed this model by labeling the DNA of bacteria across generations using isotopes of nitrogen ( patterns of DNA labeling showed the mode of replication).
Answer:
<em>Digested food is a source of potential energy</em>
Explanation:
When we digest food, the molecules of the food are broken down into smaller compounds. Chemical energy is released due to this process. Chemical energy can be used to form glucose and fat. These molecules store energy in them. When energy is required by the body, the glucose molecules can be converted into ATP and hence give energy. This energy can be used for various purposes such as it can be converted into mechanical energy for muscle movements.
