Yakvenalex [24]4 years ago
3 0

Answer:

If a solution has a higher concentration of hydronium ions than pure water, it has a pH lower than 7. A solution with a pH lower than 7 is called an acid. As the hydronium ion concentration increases, the pH value decreases. Therefore, the more acidic a solution is, the lower its pH value is.

sergiy2304 [10]
The answer is 4 diploid cells.

Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces <em>two haploid cells</em>.<span> Meiosis II is analogous to mitosis, so in total, meiosis results in four haploid cells. This is achieved through suppression of DNA replication between two meiotic divisions.
If there were no </span><span>suppression of DNA replication, then meiosis I would produce <em>two diploid cells</em>, and after meiosis II there will be four diploid cells.</span>

Of all the animals in the animal kingdom which one(s) would have the best chance for survival in mountains?
Fittoniya [83]

Answer & explanation:

Mountains are large formations of land at high altitudes, where conditions are often difficult. For example, cold weather and food shortages.

In the highest areas of the mountains, animals such as vultures, eagles, hawks and other birds of prey usually prevail.

In addition, it is common for the sides of the mountains to be covered with forests. In these areas it is possible to observe the predominance of animals such as moose, goats, sheep, skunks, llamas and lynx. This group has good climbing skills and manages to stay in the side of the mountains and in some high areas (not as high as the previous group).

Meanwhile, in the lower parts of the mountains, where the forest is denser, it is possible to observe the predominance of snakes, wolves, marmots, foxes, etc.
