Suppose two people experience the same painful stimulation (e. g., putting their hand in a bucket of ice water for one minute), but one feels less emotional unpleasantness than the other. Activation of which brain area probably differs between the two people?

A. Extrastriate body area (EBA)
B. Anterior cingulate cortex (ACC)
C. Prefrontal cortex
D. Primary somatosensory cortex (S1)
E. Secondary somatosensory cortex (S2)

Drag each label to the correct location on the image. each label can be used more than once. a scientist introduced mutations in a gene sequence isolated from bacteria. study the sequence, and identify the steps where the mutations may affect the formation of proteins. in the sequence, black letters stand for protein coding regions and red letters stand for noncoding regions. protein will not be changed. protein may be changed. attcgtgttc atcgtgttc atcgtattc attcgtattc

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.
