Question

Choose the correct explanation of how do red giants manufacture carbon-rich dust grains, and why are these important to life?1. The convection in a low-mass star in its final stages of life dredges up carbon from the core and brings it to the surface. Because the carbon can then be lost via the stellar winds, these stars seed the interstellar medium with carbon, including the carbon that is used for life on Earth. 2.

Because the carbon can then be lost via the stellar winds, these stars seed the interstellar medium with carbon, including the carbon that is used for life on Earth. 3.

Answer 1

The correct explanation is:

1. The convection in a low-mass star in its final stages of life dredges up carbon from the core and brings it to the surface. Because the carbon can then be lost via the stellar winds, these stars seed the interstellar medium with carbon, including the carbon that is used for life on Earth.

Step-by-step explanation:

The red giant manufactures the carbon rich dust grains because we see that in the final stages of its life the convention of that low mass star degrades or can be said that it dredges.

By bringing up carbon from the core and then bringing back them to their surfaces.

Stellar property: Its main and major component is mass. Their is a continuous fight because of the star's gravity and the gravity factor is directly proportional to mass.

So, mass gets affected by this. How much the star will be massive more of the gravity will be of that star.

Therefore, mass is a major factor of determining the strength of gravitational force.
