Answer:
Positive natural selection.
Explanation:
The positive natural selection is a type of natural selection that increases the frequency of an allele or trait when it is advantageous for the population. What happened in the example is that the mouth with the slight change in morphology (trait) was more advantageous for the population in the south in relation to the ancestral morphology (still preserved in the population in the north), and therefore its frequency increased. This, in turn, is due to the fact that the food (prey) is not the same in the two habitats (north and south). The specific prey in the south, caused the new morphology to be selected, (increasing the frequency of individuals with the new mouth), becasue probably that trait allows the trouts in the south to hunt more effectively.

It differs from other styles because other types of care are not around the clock, or other types require the agreement with other groups on the case management plan.

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.
Color Blindness is an X-linked trait. This explains why males are much more likely to have it than females. Offspring inherit Color Blindness from their mother, because the father only contributes the Y chromosome. A female can only have the disorder if her father has it and her mother either has it or is a carrier
