the name of the class of virus that caused covid-19

stars shine due to a process called *
1 point
fission
fusion
microwave dampening
magic light theory

Explanation:

First Question (The sun's corona is......)

• Analyze each option:
• Option 1: The corona is the outer layer of the sun, and it's fully visible only during a total solar eclipse (since the bright photosphere is blocked).
• Option 2: The lowest layer of the sun's atmosphere that gives off light as the "surface" is the photosphere, not the corona.
• Option 3: The layer above the photosphere is the chromosphere, and the corona is above the chromosphere (outermost atmosphere of the sun). So this description is not accurate for the corona.
• Option 4: The virus class related to COVID - 19 is a coronavirus, and it has no relation to the sun's corona.

• Analyze each option:
• Option 1: Fission is the splitting of atomic nuclei, and it's not the process that powers stars.
• Option 2: Stars shine because of nuclear fusion, where hydrogen atoms fuse to form helium, releasing a huge amount of energy.
• Option 3: Microwave dampening has nothing to do with the energy production of stars.
• Option 4: "Magic light theory" is not a scientific process related to star energy production.

Answer:

The outer layer of the sun that is only 100% visible during a total solar eclipse

Second Question (Stars shine due to a process called)
