Answer:
The correct answer is option C. "The magnetic field of earth keeps changing because of the suns activity"
Explanation:
The magnetic field of Earth is not a steady force, and is affected by external forces such as the suns activity, particularly during strong solar/geomagnetic storms. The changes in the magnetic field of Earth explains why the auroras Are sometimes seen at northern Ohio. The auroras are created by energetic electrically charged particles accelerating along the magnetic field, if the location of the magnetic filed changes, the location of the auroras change as well.
The correct answer is the Liver
Stretching out of wavelengths is knows as Redshift
Answer:
11. Something killed 90 percent of the planet's species approximately 250 million years ago, near the end of the Permian epoch. In the seas, just about 5% of animal species survived.
12. water bears, also known as tardigrades, are tough organisms that can withstand high temperatures.
13. DNA is found in every cell of every living creature, practically every cell in a multicellular organism has all of the DNA it needs.
14. Titan features a low-temperature version of Earth's water cycle, with liquid on the surface that evaporates, creates clouds, and then condenses to fall as rain—but the liquid is a mix of methane, ethane, and a trace of other hydrocarbons on Titan.
15. The Earth could not even support life at first. The atmosphere was devoid of oxygen, and the Earth's surface was scorching hot. The Earth gradually transformed over millions of years, allowing plants and animals to begin to grow. The Earth was then further altered by living organisms.
If crossing over did not occur during meiosis, there would be less genetic variation within a species.Also the species could die out due to disease and any immunity gained will die with the individual
