He got it right i just took that test
The Hertzsprung-Russell diagram is one of the most important tools in the study of stellar evolution. Developed independently in the early 1900's by Ejnar Hertzsprung and Henry Norris Russell, it plots the temperature of stars against their luminosity (the theoretical HR diagram), or the color of stars against their absolute magnitude
Depending on its initial mass, every star goes through specific evolutionary stages dictated by its internal structure and how it produces energy. Each of these stages corresponds to a change in the temperature and luminosity of the star, which can be seen to move to different regions on the HR diagram as it evolves. This reveals the true power of the HR diagram – astronomers can know a star’s internal structure and evolutionary stage simply by determining its position in the diagram.
The Hertzsprung-Russell diagram the various stages of stellar evolution. By far the most prominent feature is the main sequence (grey), which runs from the upper left (hot, luminous stars) to the bottom right (cool, faint stars) of the diagram. The giant branch and supergiant stars lie above the main sequence, and white dwarfs are found below it.
During the second trimester, energy needs of pregnant women are 340 more kcalories per day than those of nonpregnant women.
Answer is [ C ]
The reason is none other than,
→ Prokaryotes are commonly referred as most primitive organisms
They lacks membrane - bound organelles , they are unicellular organisms who does not posses a true nucleus .
→ Eukaryotes are most likely advanced organisms , they posses a true nucleus & membrane - bound organelles as well. There are unicellular & multicellular eukaryotes
eg : Unicellular eukaryotes like Protists
Answer:
well all loins i think live in sub-Saharan Africa well currently lions live in Asia and Africa
hope this helps also i like your profile pic ヾ(≧▽≦*)o
