Question
McLaughlin and Levin posited that a chaotic flood of ion movement initiates this biological process in the bioelectric signaling model. For 10 points each:
[10h] Name this process conducted by clonogenic neoblasts in Planaria. During this process in different organisms, activated progenitor cells migrate to the apical epidermal cap to form the blastema.
ANSWER: limb regeneration [or regrowing limbs]
[10m] In order to make space for blastema formation, this structural network first has to be degraded by elastases and collagenases. CAMs facilitate cell adhesion to other cells or to this fibronectin-containing network.
ANSWER: extracellular matrix [or ECM; accept intercellular matrix; accept ICM; prompt on matrix]
[10e] Limb regeneration is often researched using axolotls or other salamanders, members of this animal class that metamorphoses from tadpoles.
ANSWER: amphibians [or Amphibia]
