ANSWER ASAP Which statement is true about the theory of plate tectonics and the theory of continental drift?

A. The theory of plate tectonics explains how continental movements could occur.

B. The theory of plate tectonics shows that Pangaea was impossible, but the continents did move.

C. The theory of plate tectonics shows that continental movements could not have happened.

D. The theory of plate tectonics tells exactly where the continents were before Pangaea divided.

cell regulation is conducted by special proteins.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'

carbon traps heat so more of it makes it hotter causing global warming. during the ice age carbon levels in the atmosphere were low so it got very cold. so the common things between them is carbon levels in the atmosphere.
