<span>Skeletal muscle is a muscle tissue used when running a
marathon or blinking the eyes and formation of skeletal muscle comes from action
and myosin muscle fibers. Smooth muscle are found in the wall of internal
organs such as intestine and stomach. Contraction of the smooth muscle enable
the organs to performs their function while cardiac muscle is commonly found in
the wall of the heart. The contraction of the cardiac muscle enable the heart
to beats and pumps blood.</span>

Answer:
a. Excretion is accomplished by paired protonephridia with flame cells in every segment of the body. True
Most anelids have structures called metanephrids or protonephridia. Both structures are homologous to the kidneys and have the function of excresion, A pair are present in every segment of the body.
b. If the organs in one segment fail, the organs of another segment will still function. False
It is false because all segments are interrelated and have different functions depending on their location.For example, the first segment is where the sensory appendages are, such as the antennae and the eyes. The second segment is where the mouth is. There are a series of parapod segments to move, collectively called metameres and ends in a terminal portion called pigidium, where the anus is located.
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
True because the segmentation allows to have a nervous system formed by a ventral nerve cord provided with ganglia and lateral nerves in each segment.
Insects, frogs, rodents. Little stuff like that.
