Answer:

When both substances had a pH value of about 6 on the 0-14 paper  

Explanation:

The other options contemplate the case in which both substances had a pH of 3 or a pH of 9. These options are incorrect because there are outside the range of the 4.5-7.5 paper.

Another option stated that one substance has a pH of 5 and the other one a pH of 7. These values are far enough to be distinguished with the 0-14 paper.

Finally, when both substances had a pH value of about 6 on the 0-14 paper a more precise comparison is needed and the 4.5-7.5 paper can be used.

maria [59]

Answer:

when we obtain a 1: 1 ratio, in which the population is based on plants "Yy" and "yy", it is expected that the allele Y will predominate in number with each generation, in this way it can be predicted that the frequency would change to be of plants "YY" to 90% and 10% of plants "yy", a process called natural selection, so plants with many flowers and leaves will prevail, as well as the highest, becoming a cycle in which the Y allele, due to its characteristics, will become more competitive and successful to reproduce.
