Answer:

If the oil spilled in the gulf would have been processed oil, it would be worse than a normal oil spill as these oils have a higher shelf life.

Explanation:

Oil spills happen when a large quantity of oil gets mixed with large water bodies like <em>sea and oceans</em>. The oil being denser than water floats on the surface and does not mix with the water. It forms a coating on top of the water.

The difference between processed oil and normal oil is that they are heated at very <u>high temperatures</u> and this results in oxidation which creates <em>free radicals</em>, which are not good for the body and its cells. Also they have a very long shelf life due to which they will remain on water for a long time.

When oil spills happen, the <em>wind</em> cause the spill to spread over the water surface, thereby engulfing a large amount of area. The major disadvantages of the spill are:-

  • The oil gets stuck in the feathers of the birds who come by to dip themselves,
  • Animals like whale, dolphins have blow holes for releasing water. the oil covers these holes and makes it difficult for them to breathe.
  • The fur of animals like <u>seal and otter </u>gets mixed with the oil and can prove harmful to them as it gets them exposed to cold.
  • The overall BOD of the water body decreases, and organisms which use sun rays coming inside the ocean suffer as these get blocked.
  • Since processed oil has longer shelf life, a large quantity of animals will suffer and die.

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''.
