The correct answer is A. Nebula, star of seven stellar masses, a red supergiant, supernova, black hole.
Explanation
Stars have a life cycle that begins with the gravitational collapse of a gaseous nebula. Subsequently, thermonuclear fusion occurs that allows the conversion of hydrogen into helium, this causes the released energy to pass through the star and radiate in a phase called the star of seven stellar masses. After several billion years, the star passes to the "red giant" stage. Here the star contracts and raises its temperature. After this, the stars (which have masses greater than the sun) detach from their layers forming supernovae, and later, these give rise to "black holes". According to the above, the correct answer is A. Nebula, star of seven stellar masses, a red supergiant, supernova, black hole.
This is possible because of the length of the protein. It is always possible to add more amino acids and synthesize new protein and every new addition increases the number of possibilities drastically.
Answer:
Recent studies have examined the possibility that variation in species richness within communities may influence productivity leading to an exploration of the relative effect of alterations in species number per se as contrasted to the addition of productive species.
