Ok, so i have to write an expository essay for my ap bio summer assignment on the novel jurassic park, the teacher gave me a list of questions to structure the essay, i'm just stuck on one of them which asks 'what are the major scientific themes addressed in the book? ' i'm really confused on what she meant by scientific themes, i don't know what themes she's talking about, it's really stressing me out and this is the only question i'm having trouble with. ?
