Valence electrons are the electron on the outer energy level and they are important because they tell if that element is compatable
The correct answer is option (A) a tree of diverse leaves or branches. A diagram showing unlimited variations and speciation of life developing from evolution would appear as a tree with diverse leaves or branches as variations and speciations leads to diverse form of organisms in evolution.
Evolution is a process by which different kinds of organisms are formed which are diverse from the previously existing organisms. Variation and speciation are the two key factors of evolution. Variation is a change in the genetic composition of the organism making it to be well adapted to the environment. It leads to speciation. Speciation is the formation of the new species due to reproductive isolation, variation and natural selection. This also leads to the formation of new species making the process of evolution with variation and speciation resembling a tree with diverse form of leaves or branches showing deviation from the previously existing species.
Use the pH color scale. It shows acidity level of both acids and bases. You dip one of the pH strips into whatever liquid you choose, and then compare the new color of the pH strip to the colors on the scale. This will tell you the level of acidity. pH scale can be found below. As you can see, the brighter colors are more acidic than the darker and duller colors.
