"A" I think... Sorry if its not right...
The difference between butterflies and moths is a lot like the difference between frogs and toads. There are some rules of thumb you can follow to tell them apart, but there are also exceptions to those rules. Next, we'll look at exactly what makes a butterfly different from the moth and what clubs and feathers have to do with it.
Explanation:
you will end up with 24 chromosomes instead of the standard 23 and have down syndrome
I believe that the areas are tropical and polar zones.
Answer:
the magnetic direction of rocks along the surface of Earth and the age of rocks along the surface of Earth
Explanation:
The earth's magnetic field or geomagnetic field is believed to originate from the movement of molten iron and nickel in the outer core.
During a period in which the earth magnetic field is normal, crystallising magnetic minerals in magma records the orientation of the prevailing geomagnetic field. At other times when the field reverses and the magnetic field orientation changes, magnetic minerals in cooling magma stores this record.
To create a geomagnetic time scale, geologists can assign absolute ages to the records of these paleomagnetic anomalies which are the reversals. The rock is dated using radiometric techniques and each period of reversal is ascribed an absolute geologic age. Therefore, the magnetic direction of rocks along the surface of Earth and the age of rocks along the surface of Earth helps to build the geomagnetic time scale of the earth.
