A trophosome is a highly vascularised organ found in some animals that houses symbiotic bacteria that provide food for their host. Trophosomes are contained by the coelom of tube worms (family Siboglinidae, e.g. the giant tube worm Riftia pachyptila) [1] and in the body of symbiotic flatworms of the genus Paracatenula.
Lamellibrachia is a genus of tube worms related to the giant tube worm, Riftia pachyptila.They live at deep-sea cold seeps where hydrocarbons (oil and methane) leak out of the seafloor, and are entirely reliant on internal, sulfide-oxidizing bacterial symbionts for their nutrition.
Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. [1] Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver (hepatotoxicity).
As a result, people may say well-meaning—but massively invalidating—phrases to people struggling with something. Here, experts share the harm in toxic positivity and 35 phrases to think twice ...
