Despite their frequency in the intertidal zone, in tide pools, sea urchins can be found at many different depths and in any habitats. They can also be found in nearly any ocean temperature. Sea urchins inhabit the polar seas as well as the warm tropics.
<span> RNA polymerase is commonly know as DNA-dependent RNA polymerase. It catalyzes the transcription of DNA to synthesize precursors of mRNA and most snRNA and microRNA. It is found in the core of eukaryotic cells. One of which combined rRNA in the nucleolus while the rest of the chemical blends other RNA in the nucleoplasm, some portion of the core yet outside the nucleolus.</span>
Appropriately named, <u>slow pain </u>oftentimes is not detected until seconds or even minutes after an injury; this is due to the activation of chemically sensitive pain receptors.
Explanation:
According to physiology of pain, slow pain arises when unmyelinated C fibers of the muscles are activated. This is pronounced as a dull and aching pain and is more diffuse in nature rather than fast pain which are more acute and rapid.
Most of the times this pain will not be detected immediately after the stimulus like an injury but may start slowly.
Slow pain can also be burning, throbbing or even nauseous. Chronic pain conditions mostly are characterized by slow pain.
Slow pain is elicited by stimuli like mechanical, chemical or thermal which are received by the chemically sensitive pain receptors on the skin or other organs of the body.
Your answer is B my friend.. Good luck!
