Visit a museum in person and write or record your own tour of the museum. (Most museums will not allow video recorders, so you can take an audio recorder.) If you cannot visit one in person, then choose a museum we have not covered in this lesson and take a virtual tour. (The High Museum in Atlanta, The Chicago Museum of Contemporary Art, The Tate Gallery in London, and others have a strong presence on the Internet.) Describe the architecture of the building itself as well as the permanent collection. What is currently on exhibition? Upload your recording or submit your 750-word essay/tour.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
