Elements emit colours when heated because electrons in atoms can have only certain allowed energies.Heating an atom excites its electrons and they jump to higher energy levels. When the electrons return to lower energy levels, they emit energy in the form of light. Every element has a different number of electrons and a different set of energy levels. Thus, each element emits its own set of colours. See, for example, mercury and neon above. Those colours are as distinctive to each element as fingerprints are to people.
Hello. You forgot to attach the cladogram. The cladogram is attached below.
Answer:
They share a recent common ancestor.
Explanation:
The cladogram is a diagram widely used to show the relationship between the different taxes that make up the species. Using this diagram it is possible to observe the ancestry and biological evolution of living beings over the years.
Each line in the cadogram represents a living being, or a taxon that gave rise to other lines, that is, it gave rise to other living beings. In this case, in the cladogram below we can see that the two organisms highlighted in pink, have lines that originate from the same line, which shows that these organisms share the same ancestor.
