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.
Answer:
C the number of daughter nuclei is half the number of parent nuclei.
Answer:
Add native plants to a suburban garden because you are adding already flourishing wildlife
Sea Urchins are primary consumers because they eat the kelp
Sun -> Grass -> Rabbit because grass lives off of photosynthesis from the sun and rabbit eats the grass
I think there would be more biomass in grass because there is a lot more spread throughout the savannah while elephants are way bigger there is less of them.
That would be the synthesis of body mass in a primary consumer (herbivore who eats the plant).
