DNA from an extinct bird is compared to the DNA of some birds that exist today. It is shown that the extinct bird has regions of DNA that are very similar as well as regions of DNA that are dissimilar. What is the BEST conclusion, given these data?

c.more precipitation,but only when emission levels.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
