Which of the following would contribute to a more fluid state in the plasma membrane?
less double bonds in fatty acid tails and lower temperatures?
less double bonds in fatty acid tails and higher temperatures?
more double bonds in the fatty acid tails and lower temperatures?
more double bonds in the fatty acid tails and higher temperature?

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
