Our Sun is considered average because its temperature and absolute magnitude place it in the middle of the main sequence range of the H-R diagram. Correct answer: C
H-R diagram stands for the Hertzsprung-Russell diagram which was developed in the early 1900s by Ejnar Hertzsprung and Henry Norris Russell. The diagram plots the temperature of stars against their luminosity (the theoretical HR diagram), or the colour of stars (or spectral type) against their absolute magnitude (the observational HR diagram, also known as a colour-magnitude diagram).
1.Describe the three soil types. Before you learned about the biomes, which of the three would you have thought would have had the richest soil? Why?
2.For each of the three biomes, describe what you see as the biggest challenge to plants and animals--what environmental factor most drives their adaptations. (Example: For the desert, the factor would be the lack of water and heat.)
b. False
I think that decentralization is a very important process that must fulfill each country. That is why the Belgian Parliament pass laws to decentralize its government. In addition local problems can be effectively tackled only locally. The state never comes to problems of each village or town, every street or courtyard. All post-socialist countries of Central and Eastern Europe have gone decentralization. This is what gave these countries a huge boost for further development.
