What percent of energy is transferred between the levels indicated by the blue arrows?

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''.

Alexandra [31]

Answer:

White eyes are lethal in male Drosophila was the hypothesis of Thomas hunt which was valid. Hence the answer is option B.

Explanation:

Thomas hunt Morgan was a famous American biologist. He was more famous because of his experiment on drosophila which contributed most of things about the lifestyle and health science in much of the findings about those insects.

He was also awarded by the Nobel prize for his works which was related to medicine in 1933. He has also contributed many knowledge about the chromosome and heredity. he is finding is very helpful nowadays for the scientist and other biologist.

Which is unique about carbon

sergey [27]

Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules. ... They can even join "head-to-tail" to make rings of carbon atoms.

Marizza181 [45]

Answer:

The correct option is C. Drawing a conclusion

Explanation:

The scientific method can be described as a method through which all the scientific questions are tried to be answered.

The scientific method begins with a question. To answer the question, a hypothesis is generated. Experiments and observations are made to test the hypothesis. Based on the data from experiments and observations, conclusions are drawn. Hence, the statement 'based on the data, we determined that plant growth is affected by the type of soil' best illustrates a conclusion.
