HELP PLEASE I WILL MARK AS BRAINLYEST!!!!!

1.Dr. Perez is part of a team of researchers who are working on designing and building a probe to study solar flares. What condition must the probe meet? It must be able to travel over 300,000,000 km to reach the Sun. It must be able to withstand a temperature of up to 20 million degrees Celsius. It must be able to penetrate to the core since solar flares originate there. It must be able to remain in the Sun for at least eleven years.
2.Taden has found a table of the atmospheric layers of the Sun. However, he can’t make out the names of the layers in the chart.

What are the names of the Sun’s layers described in columns A, B, and C?

A: Corona; B: Photosphere; C: Chromosphere
A: Core; B: Chromosphere; C: Photosphere
A: Chromosphere; B: Corona; C: Core
A: Photosphere; B: Chromosphere; C: Corona
3.What are the dark areas on the surface of the Sun?

solar flares
sunspots
prominences
solar winds
4.The distance between planets varies as they move in their orbits. The minimum distance from the Earth to Mars is about 0.35 AU. About how many kilometers is that?

15,000,000 km
25,000,000 km
55,000,000 km
70,000,000 km
5.In order to recreate the process of energy production that takes place in the Sun, scientists use

hydrogen gas and add heat and pressure.
helium gas and remove heat and pressure.
hydrogen gas, add heat, and remove pressure.
helium gas, remove heat, and add pressure.
6.The local newspaper has published the passage below.

Last week, scientists released incredible images of aurora australis as seen from the Hubble telescope. The Hubble telescope was placed in orbit in 1990 by the space shuttle and has since delivered the sharpest images we have of our planet, our galaxy, and the universe. The images delivered last week show the beautiful display of lights all over the equator. These lights are the result of the solar activity known as solar wind. Traces of solar wind reach well beyond Earth and have been detected as far as Saturn.

Which statement in the news passage above is inaccurate?

The aurora australis cannot be seen from space.
The Hubble telescope does not orbit our planet.
The aurora australis do not occur over the equator.
Solar winds do not reach well beyond our planet.
7.Malika is writing an essay about the Sun. Below is the first paragraph in the essay.

The Sun is an average-size star that is located at the center of the solar system. This hot, glowing ball of gas has a diameter of 1,393,000 km. This means 109 Earths would fit side by side across the diameter of the Sun. At the surface, the Sun’s temperature is about 550 degrees Celsius. Earth is located just under 150 million kilometers from the Sun.

Malika quickly realizes this paragraph contains an error. Which statement identifies the error?

The Sun is a large star, not an average-size star.
The Sun is not a glowing ball of gas—it is solid.
The Sun’s surface temperature is about 5500 degrees Celsius.
Earth is located over 300 million kilometers from the Sun.
8.Suppose a scientist doing an experiment in nuclear fusion starts out with twelve atoms. How many atoms will most likely result from the experiment?

one, because atoms combine during nuclear fusion
six, because atoms combine during nuclear fusion
twelve, because atoms change but their number does not during nuclear fusion
twenty four, because each atom involved is split into two during nuclear fusion
9.Where in the Sun does the production of energy take place?

the corona
the photosphere
the core
the chromosphere
10.Scientists in a lab are working on a series of experiments that involve colliding two or more atomic nuclei at very high speeds to form a new type of atomic nucleus. What are they working on?

convection
radiation
nuclear fusion
nuclear fission

1. I believe the condition is: It must be able to withstand a temperature of up to 20 million degrees Celsius.
By measuring the relative distance between the sun to earth and the heat on earth's surface, it's predicted that the core of the sun can has a temperature of up to 27 million degrees Celsius.
To be close enough for our telescope to fully study the flares, ability to withstand 20 million degree Celsius is the bare minimum.

2. I believe the answer is: A: Photosphere; B: Chromosphere; C: Corona
Photosphere is the visible surface of the sun, Chromosphere is the irregular layers that located just above the photosphere, and Corona is the light/plasma that radiated around the stars/sun which come from the heat of its core.

3. I believe the answer is: Sunspot
In this area, there's a magnetic field flux that caused the surface temperature to be reduced.
Since other area of the sun radiate heats, these reduced temperature region appears a little bit darker if observed from afar.

4. I believe the answer is: 55,000,000 km
AU stands for Astronomical units, and 1 AU is equal to 149,597,870.7 km.
So, 0.35 AU would equal to:
149,597,870.7 x 0.35 = Approximately 55,000,000 km

5. I believe the answer is: hydrogen gas and add heat and pressure.
Currently, this model is the most well-known for thermonuclear model.
This model allows accumulations of interstellar hydrogen to be drawn into sphere of compressing gas to the point that the hydrogen undergone a nuclear fision.

6. I believe the answer is: The aurora australis do not occur over the equator.
Like the name implied, Aurora Australis could be stop on top of the australian continent.
The equator of the earth is located in the exact middle line of the earth sphere, while the australian continent located rather south from the equator.

7. I believe the answer is: The Sun's surface temperature is about 5500 degrees Celsius.
The sun surface temeperature would be the temperature that measured on the photosphere of the sun. This temperature could even got lower if we measure it on the area where sun spot occur (could fall down into 4000 degrees celcius)

8. I believe the answer is: six, because atoms combine during nuclear fusion
When we observe fusion reaction scheme, 
 Two pairs of protons would form two deuterium atoms. Each deuterium atom combines with a proton would form a helium-3 atom. Two helium-3 atoms combined and form beryllium-6 (at this state the energy becomes really unstable)

9. I believe the answer is: The core.
Nuclear fision happens in the sun core.This process produces a massive amount of energy that released towards the surface of the sun.
The effect of this release could be felt within various planets within the solar system.

10. I believe the answer is: nuclear fusion
In nuclear fusion, two or more atomic nuclei would combines and form a  more different atomic nuclei and subatomic particle, which make it become really unstable even though it produce a large amount of energy. The controlled version of this reaction is what utilized by the scientist to generate electricity using nuclear reactor.
