1) Students were comparing different phases of the life cycle of an average star. Which

student accurately identifies a connection between a main sequence and white dwart star?

Answer 1

The main sequence consists of young yellow and red stars, white dwarfs forms old and dead stars.

Step-by-step explanation:

• On average there are three major life cycles of the star and that includes yellow giants,m white dwarfs, and red giants.

• These stars are formed by the fusion reaction of H2 into He in their cores, the brown dwarfs have less mass and thus are unable to start the fusion process.

• The average star may have varied sizes and temperatures. Most of the stars are found in the main sequence which consists of 0.1 to 200 times that of the sun.

• The formation of a white star takes place due to the degeneration process and consists of a faint luminosity.
