I made a 53 on my first Biology exam. That is with reading every single chapter in the College textbooks. The next exam I watched your videos, and didn't read any from the textbook.. Made a 97. Thank you! You have helped so much
HE DIDNT SAY "i hope that's helpful".... there is no hope left on Earth...
he saved that "i hope that's helpful" for part two
@@prestonmichael7843 thank god
"And you can't get a nobel prize if you die..." Lol. I love this guy.
Thanks a lot for this video! It was very helpful.
Hillary Fan lets go TRUMP!!!
+Scott Beyer Racing ... I hate my name
We are supposed to watch this as homework for my biology class but your videos are very interesting and I wouldn't mind watching them for fun :)
What are the answers bruh
I always go to your channel when I have a science test coming up and need to review, study and take notes! Thank you for explaining it very well!
"And you can't get a Nobel prize if you die" 😂😂😂 I died
+Vy Pham So you can't get a Nobel Prize
+Epic Pander how witty ;-)
Vy Pham Reply after a year ftw!
Aw that sucks, now you can’t get a nobel prize 😂
thats sad because she cant get rewarded for her work
I never know why AT and GC always go together. it makes it more interesting than just having to memorize stuff. Thank you.
Soooo can you please be my biology prof? Mine sucks...:/ it's honestly sad how I have to spend time in class and then have to go on RUclips to actually learn. In any case carry on dude you're awesome
Martha Chase didn't "go crazy," she suffered from dementia. Big difference.
i really like the big concept map you do before you go into detail with these lessons, but i think it would be helpful if you kept a small picture of the concept map in the corner to keep track of where we are in the lesson!
without him i would fail bio
SAME
Does anybody else have to watch this on an e-learning day because of the coronavirus? hello Olympia High School students if you’re here 🤣
I do this year 😖
Thank u ...u have just helped the society
Taking the AP Biology Exam tomorrow. Definitely getting a 1 or a 2 on this :/. I just cannot understand how people understand all of this. Is it memorization? How does it come easily to people? I have struggled with this course all year. :( I am normally the Math freak and loved Calculus.
+Mr. Cool In the same boat here man, good luck
+nicolas karos Good to luck to you too man!
AP Bio to me is all about memorization of key facts and applying it many different ways and to many concepts.
What did you end up getting???
yeah how'd you do?
He didn't say "...and so I hope that's helpful"
i don't know how i appreciate you ...you are doing really really good..
This man is basically Mr.Strong's father. Without him I could not function. I love this man.
No homo tho.
forced to watch another one of your videos for homework
+Rubbert Same here😭😭
+Roberto I hope you were forced to enjoy and learn from this video too. Cause I certainly did.
same
That's a good thing
Martha Chase experienced dementia. She did not "go crazy". What's sad is that Hershey didn't acknowledge her involvement for years and she was unappreciated throughout her life and career.
you are truly amazing!
Yea I know b/c of what I'm planning to major in I'll have to take some bio courses in college as well
you're videos are SO helpful!
Very helpful! Thank you! Bozeman Science :)))
I am Chrysler k
lol. I think the person meant "college biology" in high school, as in a college course and honors course. no way in college would students need to review such simple material. They should have these basics down. And I wouldnt call it "unfair"; I'm majoring in Biology by choice.
Can you please be my AP Biology teacher!
The Hershey Chase experiment used radioactive isotopes, not dyes as stated in the video.
YOU ARE AMAZING ! Thank godddd youre on youtube
Holy, you are a really skilled teacher.
I never bragged about being in an Honors Bio class so how am I thinking highly of myself? I actually sometimes feel that I don't deserve to be in advanced classes so contrary to your belief I am not a narcissistic & vain honors student, just a girl. Anyways, I was just a bit puzzled by the fact that the other person had that material on a college bio test & like someone pointed out before, the material expressed in the video is not really college bio material (unless used for review purposes).
im useing your vids to get me through bio i came in late and youve saved my sorry but on all but one test thank you
I guess it depends where you go to school. I didn't have a Honors Bio class in my middle school which I'm guessing you did or at least you took it prior to entering high school. I didn't have that opportunity.
your videos are helping me ace my college biology final
IF IT LOOKS EASY....I DOUBT YOUR EXPLANATION!
So how does chromosome 14 fit in this picture, I've been hearing a lot of info how C-14 if turned away or embraced that dictates if the body heals itself or not? Thx
your videos are amazing!!!!!!!!i learned a lot from them.thank you.
AP Bio is usually offered to Sophomores and above, not freshmen. Bio honors/regular is a prereq for AP bio and other AP sciences at our school.
YO WHAT UP CONROYS CLASSSSSS!
Why is there a slight variation between the percentage of A and T or G and C?
mmm so it's just a coincidence that Franklin was the only woman involved and the only one not to get the Nobel Prize? highly unlikely..
+Ayako G It's less because she's a woman and more because they stole her work and didn't give her credit.
The scientific community didn't learn she was involved until after her death, and the award isn't given posthumously.
+Ayako G Yep. She died.
martha chase wasn't included in the nobel prize that alfred hershey won for the experiment that they did TOGETHER. it's sad how many women weren't honored for their scientific contributions
Gonna ace my quiz tomorrow!!
"and you can't get a nobel prize if you die.." haha idk why that made me laugh (x
Really wonderful
Thanks alot.....😊😊😊😊
Aside from that it's ridiculous in the first place how Nobel Prizes aren't given posthumously... Rosalind Franklin was not recognized for her contribution to discovering the double helix probably until a long time after her death due to the sexism in the scientific circle back in the days. Any acknowledgement to her was fairly muted and almost always coupled with Wilkins' name. It's quite sad actually.
Yea looking back I don't consider it unfair. I was never much of a fan of biology and I was stressed over my final so I guess wasn't in the best state of mind to be posting that comment. Anyways, best of luck with your major in biology! Personally, I find it biology interesting yet it's not really my favorite subject.
YOU ARE AWESOME!!!!!!!!
I love you man. You're saving my grade
Martha Chase didn't "go crazy", she suffered from dementia. And "mental illness" or "mental health problems" would be a much nicer way to call it anyway.
stfu
He didnt ask if it was helpful!!! :o
+the-screem-queen check part 2 of the podcast c:
You are awesome!
Your videos are so helpful, thank you!
you sir are a gentleman and a scholar
Hi ! Can you you have a video of DNA packing ? I love all your videos! So easy to understand!
I'm studying about this in high school right now.
your way of teaching is awesome,like your videos
love your vids for my ap bio class
Taking my NMAT this coming October
Thank you soo much, I understand Biology so much better now
"And you can't get a Nobel Prize if you're dead." Lol. You're videos really help with AP Bio! :D
very informative and educational video, very thankful .
I've noticed people are always talking about the huge yet forgotten role Franklin had in the discovery of the structure of DNA,but everyone's forgetting about Chargaff.He didn't get a Nobel prize either and his discovery was as important as Franklin's
It's really good
You do such an awesome job!!!
I don't brag, why does everyone assume that all the people who take advanced classes brag? Unfortunately, many people know I'm in advanced classes but only b/c word just kind of gets around & I've been in advanced since I was young. Anyways, I hate when people know b/c they sometimes take advantage of me & teachers from my normal classes automatically expect more from me. There's more pressure put on you from peers & educators so it's not always fun, contrary to some people's beliefs.
Thank you so much! Hopefully I score a really high on my test on this.
Hi my friend " I had A dream A couple off weeks back were I so my Cells being laserd bi mini lacers ... And just before I woke up ' I heard DNA to RNA" watt does this mean I've had A Lot off lucid dreams off late 'butt this one had words and I heard RNA " thanks ".❤️❤️❤️⚔"
For the Hershey Chase experiment I thought they labeled the phosphorus an sulfur with radioactive "tags" not dye
they did not use dye. they just used radioactivity. it was illustrated with dye because radioactivity cannot be seen in pictures.
franklin did all the work
if I come and visit Bozeman can I sit in on one of your classes?
Great video!! Im finally starting to get this :D
Im in 7th grade Science, this is so easy. Well not like THUPER EASY, just enough so that i know what he's talking about. Your videos are really easy to understand and i love watching them for fun! Thanks :)
Do you still watch them for fun even tho you like 23 now? 😂
Thank you, you're very helpful!
been there feel you bro!
I'm watching this video for our semi-final exam tomorrow...
Please tell me I’m not the only one who thinks he looks like Toby from the office 😂
And Micheal is the jealous teacher, who is not as good as Mr Anderson.🥲
"And you can't get a Nobel prize if you die." 10:06
answered my questions!! tkx
Good!!
@Dudodit yup. that's so sad..
I never said that. I was saying that why were both of us learning that same material at such different points in our academic career. Secondly, I'm not brainwashed. I know my generation isn't the best but honestly if you're so grown up, why are you stereotyping/generalizing?
"(...)and you can´t get a nobel price if you die" lmao :DD
He's laughing bc Rosalind Franklin wasn't given much credit, when she was the one who helped discover the structure of DNA the most 👀OOF
He's not disparaging the college kid, he's just wondering why they didn't get the opportunity to learn it sooner. That's the only way the "unfairness" he mentions makes sense. No need to be derisive.
hello max
Thankyouu!
Just cause they're in college doesn't mean they're taking super hard courses. I know people who are in college taking Algebra II. On the other end of the spectrum im a senior in high school taking AP calc.
Hello
This right here is the perfect example of kids you meet in highschool that can't stop bragging about taking advance classes.
poderia ter legendado né .. kkk
sou do Brasil, dou aulas de Biologia.
Do you support genetically engineered foods? are they safe?
chase went crazy further in life
*you *need *to *learn *haven't *wrong *I'm *misspelling
Unless you're a troll. Then you are a good troll.
SHOUTOUT IF YOU'RE FROM MS. HENDERSON'S CLASS BREH.
i took AP Bio when i was a freshman...why are u in honors? i was 14
yo dawg gimme the answers for my homework
U help me on my test
If you are majoring in Bio in college (I am) and going into med school (I am) then you need to take many college bio courses. I took hnrs bio like you AND ap bio in highschool and now I'm taking college bio. the fundamentals are taught in each class, but gets harder and more detailed in each class. there is no way you are learning exactly what college bio is learning but there are similarities. nice try tho...but it is not unfair
Mr. Anderson...
How am I being ignorant? I'm sorry that I was unaware that one is tested on this in college. I haven't been in college so I wouldn't know yet. Ignorant? No. Naïve maybe be a better choice of word. Not to mention that you're "surprised" that a student who works her butt off in school is in an advanced class. Lastly, how do you blatantly tell someone they are trash from a comment on a RUclips video? Sorry, I didn't know I had told you my whole life story in that comment.
College Bio Test? I'm in Honors Bio & I'm a freshman in high school & my final for this is tomorrow. Anyways why are you in college learning this & I'm 15? The unfairness is astounding ._.
"you can't get a Nobel prize if you die" looooool
