Which best describes Earth's magnetic field lines?
STatiana [176]

Answer:

The field lines go out of Earth near Antarctica, enter Earth in northern Canada, and are not aligned with the geographic poles.

Explanation:

The two poles North pole and South pole of the earth are distinct from the magnetic north pole and south pole of the earth. The magnetic north pole is the point from where the magnetic field of the Earth points downwards in the vertical direction. There is a gradual change in the magnetic poles with the passing of the time. The magnetic fields have an extension from the interior of the Earth to the outer space.

TRUE OR FALSE Two organisms that have different physical characteristics must be of a different species. True False
Paul [167]

Answer: False

Explanation:

Phenotype of an organism refers to the observed physical characteristics of an organism. The genotype of the organism is the sum total of the genetic composition of an individual organism.

Having different physical appearance does not really mean that organisms are different species because the expression of genes depends on the environment of the organism. The interaction of the genes in the organism with the environment produces different phenotypes of the same organism.
