Answer:
Aortic arches
Explanation:
Earthworms are grouped in the phylum Annelids and there body is segmented which resemble many little rings attached together. Similarly, earthworms possess circulatory system and circulate there blood through vessels. Thus, there are three (3) vessels that circulate bloods in earthworm which includes: ventral blood vessels, aortic arches and dorsal blood vessels. However, aortic arches functions like human heart thereby having the responsibility to circulate or pump blood into the ventral and dorsal blood vessels. Furthermore, the aortic arches are known to be the main portion of the artery that bends between ascending and descending aorta.
The answer is B. The process of Aerobic Cellular Respiration is glycolysis, then Krebs cycle, then the electron transport.
Answer
Nerve
Explanation:
The CNS consists of brain and spinal card that receives information, interprete it and send response.
The peripheral nervous system consist nerves that leaves the spinal card and brain and transmit or receive signals from various areas of body.
A nerve comprises of bundles of exons or dendrites surrounded by connective tissue. Sensory neurons contain afferent axons and motor neurons have efferent fibers. In central nervous system, a bundle of axons is called tract and in the peripheral nervous system it is called as nerve.
Axons are slender long projections of neuron which transmit the signal. Exon length may vary from 1um to 20um. The longest exon in human body runs from spinal cord to base of each foot.

Some of this energy is trapped in molecules of ATP, and some is lost in the form of heat. Each ATP molecule can then be transported elsewhere within the cell and used where needed. The energy-carrying part of an ATP molecule is the triphosphate "tail".
