Explanation:
This much is undeniable. Based on the magnetic fingerprints locked into ancient rocks, we know that over the last 20 million years, magnetic north and south have flipped roughly every 200,000 to 300,000 years (this rate has not been constant over the planet's lifetime, though).
This could weaken Earth's protective magnetic field by up to 90% during a polar flip. Earth's magnetic field is what shields us from harmful space radiation which can damage cells, cause cancer, and fry electronic circuits and electrical grids.
Answer:
E. ozone layer.
Explanation:
The pattern of temperature increase with height in the stratosphere is the result of solar heating as ultraviolet radiation in the wavelength range of 0.200 to 0.242 micrometre dissociates diatomic oxygen (O2).

Abiotic and biotic factors are what determine where an organism may live and how much a population can grow. For example, an organism needs water to be able to live and a population also needs water to be able to live as well. Without water, neither organism or population would be able to survive/grow.
