Annelids. Worms are the simplest bilaterian animals, and reveal the basic structure of the bilaterian nervous system in the most straightforward way. As an example, earthworms have dual nerve cords running along the length of the body and merging at the tail and the mouth.
If your observations had not been restricted to the area of the root tip that is actively dividing, how would your results have been different?Cells are in interphase 90% of the time, and, since most of the creation of plant cells occurs in the root tips, you would witness mostly interphase. 2.Based on the data in Table 3.1, what can you infer about the relative length of time an onion root tip cell spends in each stage of cell division?Most of a cells life cycle is spent in interphase. Metaphase is the longest stage of mitosis, and anaphase is the shortest.1.List three major differences between the events of mitosis and meiosis.Meiosis has four nuclear divisions, whereas, mitosis only has one; meiosis creates four haploid cells, whereas mitosis creates two diploid cells; and meiosis is the only one taking part in crossing over.2.Compare mitosis and meiosis with respect to each of the following in Table 3.2:Table 3.2Mitosis MeiosisChromosome Number of Parent Cells2n2nNumber of DNA Replications11Number of Divisions12Number of Daughter Cells Produced24Chromosome Number of Daughter CellsDiploid (2n)Haploid (n)Purpose/FunctionRepair and GrowthGamete and Spore

Correct answer is label B. on the purple shaded area which is inside the ventral horn and dorsal.
Spinal cord is termed as tubular or long thin structure which is made of nervous tissue. It is being extended to the lumbar region which is found in the brainstem from the medulla oblongata.
This is enclosed in the central canal which contains cerebrospinal fluid of the spinal cord. If we combine spinal cord and the brain we come up with Central Nervous System.
Between the second and first lumbar vertebrae is where spinal cord extends and it is where it ends.
<em>The major function of spinal cord is nerve signal transmission from motor cortex to body. </em>
