Mutations and natural selection cause adaptations. Mutations can cause instant adaptations, while natural selection is the process by which adaptations occurs over a series of generations.

Adaptations are changes or processes of changes by which an organism or species becomes better suited for its environment.

Mutation is when something happens in the genes and something changes, such as it was FF and now its Ff. Natural Selection is when organisms are better adapted to their environment then other organisms. Adaptation is adapting to your environment or being adapted to it already.

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;

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

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

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

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

<u />

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

''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''.
