Answer:
d
Explanation:
Your heart is an organ that’s largely made up of muscle. It has the vital function of working to pump blood to the organs and tissues of your body.
A diverse range of clinical syndromes with a shared anatomic location inside the basal ganglia are known as basal ganglia disorders.
<h3>What is functional anatomy of basal ganglia disorders model ?</h3>
A model in which particular types of basal ganglia disorders are associated with changes in the function of subpopulations of striatal projection neurons. This model aims to explain the variety of clinical manifestations associated with insults to various parts of the basal ganglia.
- This model is based on an analysis of post-mortem anatomical and neurochemical data from humans and experimental animals. The excess of aberrant movements that characterise hyperkinetic diseases are thought to be caused by a specific dysfunction of striatal neurons that project to the lateral globus pallidus.

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.
Final speed - Initial speed / time.
50.0 - 20.0 / 5.0
30.0 / 5.0
= 6.0 (km/h)/s
Correct choice is B.
