If the ph of the body gets too low, below 7.4, acidosis results. acidosis is serious because many of the chemical reactions that occur in the body are ph-dependent. if the body's ph drops below 6.8 or goes above 7.8, death may occur. because of this, we have buffers in the blood to protect against large changes in ph. as seen in the above reaction, the human buffer system depends on the fact that

The similarities of organisms in which two areas numbered above provide the best evidence for common ancestry between organisms in both locations?

Step 1 review the imaginary strand of dna below. note the complementary base pairs. a g c a a t c c g t c t t g g t c g t t a g g c a g a a c c step 2 to begin replicating this strand of dna, draw the two sides of the strand separating. step 3 now, draw the free-floating bases linking up with the separate sides. remember to follow the rules of complementary base pairing. step 4 draw the two resulting dna strands.

Dna replication occurs in preparation for
