anyanavicka [17]

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).

olga55 [171]

The question is not complete but it can be answered in general as the plants cannot survive in acidic conditions.

Answer: High acidity is harmful to this type of plant.

Explanation:

The plants that were kept in the higher acidic conditions are less likely to grow in higher acidic conditions.

The plants that were kept in more basic conditions will also not grow properly as the pH of the soil should be neutral, slightly acidic or slightly basic.

The plants that was kept as a control on the pH of 7 will grow the best as the pH is optimum for the growth of the plants.

The conclusion is high acidity is harmful for the life of the plants.
