Both cutterlike claws are removed in the fifth stage and a crusher claw develops on the left side.
Both cutterlike claws are removed in the fourth stage and a crusher claw develops on the right side.
24. It can be inferred that of the two laboratory environments mentioned in the passage, the one with oyster chips was designed to
prove that the presence of oyster chips was not necessary for the development of a crusher claw
prove that the relative length of time that the lobsters were exposed to the oyster-chip environment had little impact on the development of a crusher claw
eliminate the environment as a possible influence in the development of a crusher claw
control on which side the crusher claw develops
simulate the conditions that lobsters encounter in their natural environment
25. It can be inferred from the passage that one difference between lobsters in the earlier stages of development and those in the juvenile fourth and fifth stages is that lobsters in the early stages are
likely to be less active
likely to be less symmetrical
more likely to lose a claw
more likely to replace a crusher claw with a cutter claw
more likely to regenerate a lost claw
