(1) What is the most common way for a dead organism to avoid decomposition? (2) Why do researchers look for fossils in places that are now dry and barren instead of
other places like forests or grasslands?
(3) What kind of dating from the lecture or textbook would be the best method for finding
the number of years ago when a volcanic rock was formed?
(4) Why is the pelvis of a biped shorter and wider than the pelvis of a quadruped?
(5) Does the overall shape of Lucy’s pelvis resemble the human pelvis or the chimpanzee pelvis more? Do not think of the size, but compare the outlines of each bone.

(i)The most common way for a dead organism to avoid decomposition: The body could be buried in a sandstorm.

(ii)Dry and barren places have high erosion that reveals fossils. Dry and barren places are comfortable for heavy phyiscal labor.

(iii)Radiometric dating methods

(iv)In a quadrupedal pelvis, the ilium lies lateral to and parallel to the vertebral column and the ischium extends dorsally. ... In a bipedal pelvis, the ilium is shorter, wider and expanded front-to-back. Where the ilium articulates with the sacrum is wider, providing greater stability and support.

(v)Lucy has a more humanoid pelvis because she was a hominin.

Explanation:

Hope it helps :)

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !

the answer is cell division : )
