Chromosomes are what the mother and father donate to the fetus in order to compose your basic genetics
The father gives half which is 25 and the mother gives 23
The reason for this is when a baby is being created it is given a gender. That gender is either boy or girl the boy has an added chromosome at the near middle of gestation and the girl lacks that last chromosome so thats why the father gives more chromosomes than the mother
A group of nerve cell bodies outside the central nervous system of the body is called as ganglion. The nerve is an enclosed cable like bundles of axons. A neuron is a nerve cell (electrically excitable) that receive, process and transmit signalling information through electrical and chemical signals. The tracts are the bundle of fibers that connects nuclei of the central nervous system. The nerves, neuron and tracts are present outside the central nervous system. Hence, only ganglia persists in the central nervous system.
Zebra mussels will take over an ecosystem and deplete resources that species indigenous to the area require to survive.
