The answer would b a so the top person is correct:))
Answer:
Vitamin A
Explanation:
Vitamin helps corrects deficiency and improve night blindness.
The hydrogen ion concentration of the following pH samples is as follows:
- 7 (a neutral solution) = 0.845
- 5.6 (unpolluted rainwater) = 0.748
- 3.7 (first acid rain sample in North America) = 0.568
<h3>How to calculate hydrogen ion concentration (H+)?</h3>
The pH is a measure of the concentration of the hydrogen ion (H+) in water. This means that a relationship exists between H+ and pH of a solution.
The mathematical relationship between pH and H+ concentration ([H+]) is as follows:
pH = –log [H+]
This means that the hydrogen ion concentration (H+) of the following pH values can be calculated thus:
- log 7 (a neutral solution) = 0.845
- log 5.6 (unpolluted rainwater) = 0.748
- log 3.7 (first acid rain sample in North America) = 0.568

missense mutation
Explanation:
Answer:
The mice population do not involve in the same line.
Explanation:
The gene flow refers to the transfer of the gene from one population to another population and natural selection is the mechanism in which the survival rate and reproduction of the population are decided by the nature following the rule of the survival of the fittest.
In the given question, the mice population got separated due to the river which acted as a barrier between the mice population. The presence of this barrier reduces the chances of the gene flow between them as it is impossible for the mice population to cross the river.
As a result of this, the mice population will start surviving in different regions on both the sides of the river where it is not necessary that the same environmental pressure will act on the population of the mice.
Thus, the mice population do not evolve in the same line.
