Specific. The taxonomy of the dog reflects that he is a member of the animal kingdom, or Animalia. The
phylum Chordata, which includes those animals that are chordates or vertebrates, meaning they
have a backbone. Dogs are classified in the class Mammalia, so they are mammals. Besides
mammals, remember that other classes of chordates include fish, birds, reptiles, and
amphibians. Dogs are further classified in the Carnivora order and the Canidae family. The genus
Canis and species lupus of the dog are the same as that of the wolf. The dog is then classified as
a subspecies, familiaris, of Canis lupus.

answer: a chemical reaction

explanation:

im not wrong

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
