dalvyx [7]

An area of the body that provides afferent, sensory information to the cns and receives efferent , motor information from the CNS is called a: <u>The Somatic Nervous System.</u>

  • There are two main categories of neurons in this system: movable neurons Motor neurons, also known as efferent neurons, transmit information from the brain and spinal cord to muscle fibers all over the body.
  • The somatic nervous system is a part of the peripheral nervous system that is involved in the voluntary control of skeletal muscle movement.
  • The cranial nerves, which transmit information from the brain to the head and neck region, are an illustration of the somatic nervous system.
  • In this area, conscious motor functions are under the control of the somatic nervous system.
  • There are two components to the somatic nervous system: Spinal nerves are mixed nerves that send motor orders into the spinal cord and sensory data into them. The nerve cells that make up the cranial nerves.

classify the following characteristics and examples depending on what model of speciation is described.
kvasek [131]

The classification of the characteristics and examples based on the model of speciation that is being described are as follows:

  1. <u>Allopatric Speciation:</u> speciation that is based on geographic isolation.
  2. <u>Sympatric Speciation:</u> organisms are reproductively isolated by postzygotic mechanisms and evolve into different species.
  3. <u>Allopatric Speciation:</u> organisms in different locations are subject to different selective pressures and evolve into different species.
  4. <u>Sympatric Speciation:</u> speciation that does not require geographic isolation.
  5. <u>Sympatric Speciation:</u> bread wheat evolved from two species of wheat with different chromosome numbers.

<h3>What is speciation?</h3>

Speciation can be defined as an ecological and biological process through which new species of a living organism are formed, especially due to isolation of a part.

<h3>The types of speciation.</h3>

In Science, there are five (5) major types of speciation and these include the following:

  1. Allopatric Speciation
  2. Peripatric Speciation
  3. Parapatric Speciation
  4. Sympatric Speciation.
  5. Artificial Speciation.
