Answer:
<em>The correct option is limited food and water resources favored the survival of smaller deer.</em>
Explanation:
The islands where the Key deer lived had limited food and water resources. As migration was not possible for these species because the white-tailed deer had more adaptations as compared to them, hence they had to somehow survive in these areas with limited food and water resources. Limited food resources were the reason that the Key deer could not grow properly and hence evolved to have very little weight.
The answer to this question is Fossil Fuels
The electrons in the outermost shell of the covalent compounds are shared by nearby atoms. As there are no free electrons for conducting electricity, the covalent compounds are perfect insulators at absolute zero. As the temperature increases, some electrons move from valence band to conduction band. This gives rise to conductivity. But as the numbers of charge carriers are very low, covalent compounds are poor conductors. On the other hand metals are good conductors cause of their bonding. Metallic bonding consists of a sea of electrons rather than discreet bonds. The free electrons are able to move freely. Since electricity and heat need electrons to move, the bonding promotes conductivity.
