The answer is D. The life cycle of a star is dependent on its mass. Stars by forming at nebulas as protostars. When the sun exhausts hydrogen fuel at its core, the core begins to fuse helium to carbon and the core becomes hotter but smaller. The outer layers are pushed outwards and the sun becomes larger and paler. Later, the helium fuel begins to run out and the sun loses the outer expanding layers into a planetary nebula. The remaining core is a white dwarf.
Stars that are 10 times our sun's solar mass just explode to supernovas when their hydrogen fuel is exhausted.
To thrive in a broad range of environments, including soil, water, and eukaryotic cells.
The more plants and animals in a habitat, the greater the biomass, which is now habitats store energy. The greater the number of species the more competition there is for food between predators, which sustains their populations
Answer:
Hey there!
This can be explained using the conservation of angular momentum, which the planets get attracted to the sun because of its large size, and massive gravitational pull.
Let me know if this helps, or if you need a further explanation :)
Digestive reactions where large molecules are broken down into smaller ones called catabolism.
