[@alexkaram7343]

I love this guy. He's going to save me this year for bio. Thank you for making these.

[@ebsaeshete4395]

Thank you so much for taking the time to make these videos, they are really great help!

[@anna-et1kk]

These videos help so much! Cured my ap bio anxiety :)))

[@helenankomah1953]

you are the reason i love biology! Thank you!

[@benlewis4148]

When you hear the "can haz cheeseburger" meme in 2016 :(

[@marmarmmgirl]

Ben Lewis :((

[@briannauquillas]

imagine hearing it in 2020

[@thefirehydrationunit5887]

2022

[@antsriazhang5450]

2023?

[@lenawu8067]

Thank you su much!!!!!!!! really clear illustration and really useful study resource!

[@masterno8576]

whoever is struggling with this lesson. DOnt waste your time cuz he is your guy!

[@alyssa29002]

that poor cat became an example for having a lot of "hydrocarbons" hahaha

[@antsriazhang5450]

ramble for two minutes straight cuz he is afraid about if he explained enough.... Then he realizes that he talked about absolute NOTHING and cleans it off and wastes two minutes of his time :( Thanks for spending so much time in this man!

This guy is the goat

[@Rara-yz8wm]

is watching the videos from this ap bio playlist enough to prepare for this years exam?? like do u cover the whole material in these vids??

[@antsriazhang5450]

Probably not

[@nicko7146]

Man, your videos are so helpful! Thank you, you help me a lot! Do you think Campbell Biology is the best book for introductory biology? Are there any alternatives? What do you think about OpenStax?

[@cash-n8e]

The Campbell is usually for the intro biology course for bio majors and all the likes and the open stax is for the non major biology

how can I know if 2 isomers are enantiomers or not? I understand the hands' differences but I can't really know whether two compounds are the same or not.

[@ScienceWithJohnston]

If they have the same formula and atom arrangement they are the same thing. If it's the same formula but there are 2 different mirror image arrangements it is an enantiomer. If the structure is flipped at a middle bond, that is geometric, and if there are major rearrangements it is structural. There are others terms used for some of these as well that can be confusing. Like structural isomers are often called constitutional.

I think I love you

[@nhanle3862]

Great Video Thanks!

[@cavinmuff1415]

nice vid

[@HarryPotter-un1me]

Quick Question: I'm don't quite understand what the difference between an isomer and functional group is. Could someone help me?

[@antsriazhang5450]

Not me :( Ask Hermione

[@brandonli3996]

that cat is so cute

[@antsriazhang5450]

CATS are cute!

[@maahumy]

most of the videos cutt off too early at the end :(

[@ScienceWithJohnston]

They actually don't cut off because there was more, they cut off because I then rambled on stream of consciousness for 2 minutes about nothing before admitting I was finished. I then used my amazing editing skills to just cut it off before my verbal diarrhea really kicked in.

[@Mariam-iq4if]

@@ScienceWithJohnston Informative AND funny. What more could you ask for in a youtube channel?

[@antsriazhang5450]

Is that a sickness or noo?

[@tarekmasad8517]

What a strange claim! Do you really know the mechanism that makes things alive ?!

[@ScienceWithJohnston]

You will need to be more specific. It has been a while since I recorded, but I can tell you "alive" is a concept created and defined by people. So I can confidently say what "alive" is by using the definition generally agreed upon by scientists. Not sure what else you are aiming for with your comment...
