Which symptom would most likely occur in an organism exposed to tetrodotoxin

The right naswer is D.paralysis due to lack of action potentials to signal muscle tissue.

Tetrodotoxin (TTX) is a toxin (neurotoxic) isolated for the first time in 1909 and present in some species of fish, tetraodons.

It is also called Fugu poison, and tetraodon poison.

Tetrodotoxin is a potent neurotoxin produced by four different strains of bacteria: Aliivibrio fischeri, Pseudomonas sp, Vibrio altermonas and Vibrio alginolyticus.

Tetrodotoxin selectively blocks the pore of voltage-gated sodium channels, thus preventing the passage of nerve impulses. This blockage under a certain level is reversible.

The clinical picture is as follows:

* Impairment of the nervous system with oral and perioral paresthesia, nausea often accompanied by vomiting, sometimes with diarrhea and abdominal pain;

* Dizziness, pallor, feeling unwell, then ataxia and general numbness with the sensation of floating. * Tingling and tingling of the extremities preceding paralysis of the lower limbs and extremities;

* Changes in deep sensitivity, throat and larynx are affected very early causing dysphagia or complete aphagia, and dysphonia;

* Dilation of the pupils (mydriasis);

in the case of acute intoxication, bradycardia and hypotension, hypersalivation, hypothermia, hypersudation, asthenia;

* Cyanosis of the extremities and the lips, petechial haemorrhages on the body.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.

sorry to break it to ya but no one can answer your question it's just

jk but i am serious about the part that most people cant answer it beacuse you did not mention the section you are talking about. but it would if you added some detail and were a bit more specific.
