Hi John,
I'm a bit confused about the new curriculum,in particular about this topic which is on pheromones. Thus, I need to ask you a few questions:Is it common for both SL & HL students? Is this topic a unit on its own or is it related to the unit on hormones? Thanks in advance!

This is for both HL and SL and is separate from hormones

Dear Hana

Sorry, I was away last week. Thank you, Gareth, for answering the question! Yes, all content for Paper 1 is the same for SL and HL, except for the HL extensions. Students need to be able to write an SAQ or an essay for all content on the exam. For the HL extensions, the content may only be assessed in essay style on part b of the exam.

Yes, it is possible, but knowing that it is not a pheromone in humans.
