Yes, pH of the soil affects the colour of flower.
Flowering plants grown in acidic soil (pH<7) bears blue flowers or at has a blueish tint.
Whereas, Flowering plants grown in Neutral (pH=7) and Basic (pH>7) soil bears pink and red flowers.
A plant's flower color is determined by a complex balance between chlorophyll, beta carotene, flavonoids,etc in particular pH of the soil to give out vibrant colors like red, blue, pink, yellow,etc.
Answer:
It ocurred a selection by allopatric speciation
Explanation:
The allopatric speciation refers to the evolution in which the same specie starts developing different characteristics because of geographic barrers and this characteristics after some time generates two different specie.
It happens because usually according to the environment or the predators, species have to develop different adaptations so they can survive. In this case we have two different types of camouflage adaptations made by the salamanders acording to the conditions so for one specie it is better to camouflage from the predator mean while to the other is better to use lived colors to seem as it is a poisonous animal and in this way avoid the predators.
So you can see the same specie develop different strategies to survive because of a geographic separation, generating an allopatric speciation.
Effacement: The cervix – which is normally long and thick, measuring about 1-2 inches, starts to get shorter and thinner. This process is known as effacement. As the cervix gets more and more effaced, it gets shorter and shorter and “pulled up” into the lower part of the uterus.
Dilation: At the same time, the cervix softens and begins to open up – known as dilation. This widening, allows a smooth passage for the baby’s head and the rest of the body from the uterus into the vaginal canal.
