According to the bell magendie law, " the ventral spinal roots transmit motor impulses and the posterior roots sensory impulses,which establish a major landmark in the history of neuroscience."
The nature and physiology of the phenomena were described independently by sir charles bell , he is British anatomical scientist and french physiologist francois magendie after that Johannes peter muller confirmed it.
The ventral roots preganglionic sympathetic fibers of the atomic nervous system exit the spiral cord with ventral roots T1 through L2. It consist predominately of efferent somatic motor fibers. There are also 31 pairs of spinal nerves and roots. Eight pairs of cervical nerves exit the cervical cord at each vertebral level.

EPDs are computed using production data that registered seedstock members have provided to the breed organizations. Based on ancestral data, individual performance data, and progeny data as they become available, this information is entered into statistical matrices to generate the estimated Page 2 breeding values of animals.
Answer:
Explanation:
Increased nitrogen level in ocean water can lead to excessive growth of aquatic plants in the ocean which in turn leads to high oxygen (dissolved oxygen) uptake by these plants when they decompose. The overgrowth of these plants also prevent light penetration in the ocean water. All these can affect other aquatic organisms particularly those that depend on these dissolved oxygen and/or light penetration (such as fish and crustaceans).
Abiotic factors are things in an ecosystem that aren't alive.
Here are a few examples of abiotic factors in a rain forest:
1. Sunlight
2. Water
3. Soil
4. Rocks

The endosymbiotic theory opposes that mitochondria in eukaryotic cells rose from C. Endosymbiotic prokaryotes that metabolized oxygen.
