B) Photosynthesis The Sun is the ultimate source of all energy in the universe. Plants being the main primary producers or autotrophs, use solar energy to make their own food through photosynthesis, thus converting energy into the organic matter that can be consumed by all organisms. They  form the basis of almost all food chains from where consumers derive their food.

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''.

use newton's first law of motion to explain why you feel tossed around whenever a roller coaster goes over a hill or through a l
Leya [2.2K]
Newton's First law of motion:  An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force.
This is also known as the law of inertia
Anyways,  you feel tossed around because unbalanced forces are acting upon you while riding on a roller coaster.  Hope this helps!
