I think it is B it should be but I could be wrong
Explanation:
I dont have an explanation
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.
A, b, and c are all correct.
take for example finches off of the galapagos islands. they vary from island to island, yet are still the same bird. on one island they have bigger, more durable and stronger beaks, because that island has many nuts to crack open and eat. on another island, they have thin ling beaks, ideal for pecking at insects in the grass on tree bark. evolution is literally survival of the ifttest, where those equipped best will live and those without means to fight for life will die off, leaving those most capable of reproduction and passing down genes.
Answer: c. If you cut an onion near a person, then his/her eyes will always begin to produce tears
Explanation:
Water is Hydro itself , Glucose dissolves in water so its hydrophilic , Cl- makes HCl by reacting with water , only Fat is hydrophilic because u cant make a compound or make fat and water react , they dont react and if u put fat in water or water in fat they keep up with a shape dont mix with each other , so fat is hydrophobic
