What can be concluded about the initial mass of a blue sequence star compared to a red main sequence star

A blue arrangement star will be littler and more blazing than the red fundamental grouping star. A B-type principle succession star (B V) is a primary arrangement (hydrogen-consuming) star of phantom kind B and glow class V.

These stars have from 2 to multiple times the mass of the Sun and surface temperatures somewhere in the range of 10,000 and 30,000 K. B-type stars are very glowing and blue.

A blue sequence star will be smaller and hotter than the red main sequence star. Blue stars are also older that red stars, and they are usually towards the end of their lifetime.

the answer is:

in a biology class, the teacher started explaining a new lesson about the dna structure. personally, i found this lecture hard to understand. so i decided to use my critical thinking skills to be able to understand it. i analysed the different ideas, and broke them down into smaller parts to assimilate each. then i started evaluation and tried to link what i am learning with real life experiences so that i can make sure that i know how everything i am learning relates. finally, i started questioning by researching more what i learned and asking more questions that can me through my learning process. reflecting on the information meant that i should review it. all this me greatly understand what i previously found hard to understand.

hope it !
