Myelinated nerve fibers that rapidly transmit acute pain information from the sensory fibers to the central nervous system are _______

Answers

Answer 1
Answer:

Answer:

Delta fibers.

Explanation:

Myelinated fibers may be defied as the fibers that are covered by the myelin sheath. Three different classes of nerve fibers are group A nerve fibers, B fibers and C fibers.

Delta fibers are the type of group A fibers. These fibers are involved in the transmission of the acute pain information. The information is transferred from the sensory fibers to the central nervous system. These delta fibers can carry information faster and they are larger than the C fibers.

Thus, the correct answer is delta fibers.

If thermohaline circulation were blocked, perhaps by plate tectonics, what would happen?Nothing would change.

Global climate would be significantly affected.

Coastal areas would warm up.

There would be an increase in precipitation.

Answers

The answer is Global climate would be significantly affected. Themohaline circulation plays an important role in global climate. Thermohaline circulation is the flux of ocean waters and surface currents that are related with three gradient of densities. The density of sea water is determined by the content of salt. The currents of wind on the surface and of water in the oceans transport matter and energy, which translates into heat transfer; thi is the reason of the impact of the circulation on the climate. It is thought that changes in thermoline circulation will cause changes in polar sea ice, changes in Earth's radiation, changes in the concentration of carbon dioxide, and, consequently, changes in temperatures.

What is the main difference between adaptive radiation and other forms of speciation? Adaptive radiation is a mechanism for evolution. Adaptive radiation happens over a relatively short time. Adaptive radiation requires a founding population. Adaptive radiation occurs only on islands.

Answers

Answer:

The correct answer would be "Adaptive radiation happens over a relatively short time".

Adaptive radiation refers to the process of evolution in which ancestor organisms diversify rapidly into a wide variety or new forms as a result of environmental changes, availability of new resources, availability of new niches, or new challenges.

Accumulation of adaptive radiations over a long period of time results in speciation.
