The ganglia are formed from the cell bodies of a group of neurons. The ANS or autonomic nervous system associates with the CNS (central nervous system) and the somatic nervous system with the help of ganglia. The ganglia accommodate the cell bodies of sensory (afferent) and motor (efferent) cell bodies of the ANS.
The sympathetic ganglia are situated near to the central nervous system. The two sympathetic ganglia, which locate the cell bodies of post-ganglionic cell bodies are sympathetic trunk ganglia (situated alongside the vertebral column) and collateral ganglia (anterior to the vertebral ganglia).
Chordates
Chordates have the 4 unique characteristics, postanal tail, notorchord, pharyngeal gill slits and dorsal-hollow nerve cord. Lancelets is the group of chordates that has a notochord and includes separate males and females.
Lancelet exhibits the four basic characteristics of phylum Chordata. It has a dorsal nerve, a notochord, a post annul tail, and pharyngiall gill slit.
Jawless fish, cartilaginous fish, and bony fish have notochord when they were still young but it was replaced by a vertebral column as they mature.
<span>Lancelets are included in the subphylum cephalochordata. Cephalochordates are gonochoristics. It means that the sexes are separate. Both sperm and eggs cells are released in the water where fertilization occurs.</span>
<span>.Chloroplasts and bacteria are Similar in size.</span>
The answer is: D.<span>New Moon, Waxing Crescent, Quarter Moon, Waxing Gibbous, Full Moon, Waning Gibbous, Quarter Moon, Waning Crescent</span>
