The causes of gender dysphoria are not yet fully understood. A personâs biological sex is determined by two chromosomes â one from the mother, and one from the father.5 Early in pregnancy, all fetuses are female because the X chromosome (which is inherited from the mother) is the only active chromosome.
Paralytic shellfish poisoning (PSP) is one of the four recognized syndromes of shellfish poisoning, which share some common features and are primarily associated with bivalve mollusks (such as mussels, clams, oysters and scallops).he toxins responsible for most shellfish poisonings are water-insoluble, heat and acid-stable, and ordinary cooking methods do not eliminate the toxins. The principal toxin responsible for PSP is saxitoxin.
Examples of these include moray eels, sea bass, piranhas and sharks. Shellfish are found in freshwater as well as sea water and include shrimps, prawns, oysters, cockles, clams and mussels.They are also known as âfilter feeding molluscsâ which means that they use a filter process as they feed upon algae and plankton within the surrounding water.n this case, the shellfish contain a type of toxin called âbrevetoxinsâwhich cause symptoms very similar to those of paralytic poisoning or ciguatera poisoning. Symptoms of neurotoxic poisoning include: 1  Numbness/tingling in the mouth, arms and legs.
