True

Campbell uses categories like group and supergroup instead of Kingdom and Phylum ...
To confuse students
To address the ambiguity surrounding taxonomy
Instead of guessing
Because a lot of PhD's and scientists who helped him edit this book agree (not all)
There is some truth to all of the above (maybe not confusing students, but sometimes it feels that way)
Heterotrophic pathogen, Salmonella, is a problem for us when the toxin gets into our system from undercooked, or mishandled poultry, or other (yes other) reptiles. When properly prepared, it is no longer an issue. What does the cooking do to the toxin?
agitates it, causing it to toxify itself, rendering it harmless
denatures it, change in shape, rendering it harmless
hides it within the charred flesh of the poultry, making it safer to eat.
liquifies it, making it easier for our digestive enzymes to handle
Physarum, the genus of plasmodial slime mold, is the only organism that we are dealing with in this chapter that is found under the supergroup [x]
