Answer:
[a] varies in its characteristics according to local environmental circumstances
[b] becomes common within a species through natural selection
[d] tends to promote the well being of an organism in its natural or social environment
Explanation:
The adaptive traits in the living organisms have a simple basic role, that is to make the organism better suited for survival in its environment. The adaptive traits come in all sorts of different shapes, be it some that are manifested in the physical appearance or in the behavior of the organisms. Adaptive traits can be increased speed, prolonged neck, living in a groups, developing thorns and many more. This type of traits occur when the organisms face increased competition or when the environment in which they live starts to change, so in order for them to survive, they start to develop traits that will make them better suited for the new conditions and more competitive. The main principle through which the adaptive traits are transferred and rapidly increase in a population is through natural selection, as the organisms choose the ones that have advantageous traits for their mates, while they live aside the others.
A. The spelling of the two words might be similar and some sounds might be the same.
Although it is possible for words in two different languages to have the same spelling and/or pronunciation, it is much more likely that they would be similar. Since, the languages are derived from the same root and belong to the same family, it would make sense that the words would be similar, if not exactly the same.
<span>The oldest rocks are Early Proterozoic metamorphic rocks</span>
They are believed to cause divergence of lithospheric plates at the <span>mid atlantic ridge
</span><span> The currents reallocate heat from a certain place to another through mass motion of fluid (such as molten rock or water), The difference in temperature between core and lithosphere material generate enough force for the divergence to happen.</span>
