Answer:

Reproduction is one of the most important characteristics of living beings, because -

- The existence of any species is dependent on the reproduction because no living being is immortal.

After death of a being of one generation,the existence of that died being is completed by the newborns of the next generation.

And,the birth of newborns of next generation is only possible by the reproduction.

- The variation and mutation in the biological characteristics is often necessary which is only possible by reproduction through many generations.

- When a living being becomes old, it's become unable to do normal tasks like collection of food, finding shelter etc,at that moment,the newborns of next generation do the necessary jobs.

And as mentioned before,these newborns are only possible due to reproduction.

Pain signals often have two components: an acute sensation of "first pain" which is felt almost immediately after an injury, and

o-na [289]

Answer:

This suggests that neurons that send the signals that we perceive as first pain Myelinated Tpye A-delta___, and neurons that send the signals that we perceive as second pain Unmyelinated-Type C.___.

Explanation:

Physiologically, primary afferent neurons that innervated the the touch, pain, temperature,and pressure receptors in the effectors to input sensory signals to the spinal cord and the brain are categorized based on their diameter, sizes, and nature of myelination. Based on this;

A-alpha has the largest diameter, myelinated, and sensitive to sensation from the muscle cells

A-beta are next in diameter, myelinated and sensitive to sensation of touch.

A-delta followed in diameter, and size. They are mylinated, and sensitive to pain and temperature.

C-fibres are least in diameter, they are unmyelinated, but sensitive to pain, touch and temperature.

Therefore, if the speed of conduction,of action potential in a neuron depends on the diameter(thickness) and myelination of the axon(saltatory conduction) :

''then, acute sensation/ first pain should be transmitted by the A-delta fibre. While the the slower/second pain should be transmitted by the slower unmyelinated - C-fibres''.
