ArbitrLikvidat [17]

c. Annelids possess both circular and longitudinal muscles that produce waves of contraction that are propagated down through the points eBookseries of segments.True

True because anelids have circular and longitudinal muscles that serve to function the hydrostatic skeleton.

d. Segmentation has allowed for specialization in the anterior of the annelid body, which has provided for a more sophisticated nervous system. True
