it means that the reflex ( which means something you do without thinking) to turn away from each other while vomiting is old. they compare the reflex to the nausea ( nausea is a stomach sickness that can lead to vomiting) that made them vomit.

you wouldn't change the 見る at all, you only conjugate the verb to have a different meaning of the sentence, so unless you're saying like he was able to see, or something you change it. if it's just he looks it's just 見る. if you want to get technical, it's probably better to say 見ます[emoji][emoji]

I'm on the fence honestly. I'm American, and while I really really like the British accent, I don't like British slang or the different terminology. I remember when I was little I had a British children's book for some reason and the mom would say "I'm going to collect the children" and it always weirded me out

coordinate means to get together to do something, usually used for making plans. sentence example: Let's coordinate our plans for Sunday evening. collaborate means to work together on something. Sentence example: We decided to collaborate on our class project. cooperate is similar to collaborate but it's more used for saying that you helped with something. Sentence Example: The man cooperated with the police. Collaborate is used mostly to describe plans or projects, such as art or music. Cooperate is more like someone helped alittle bit on something. I hope this helped!

They have the same meaning :) puzzled is more common. Using perplexed makes you sound smart!
