Mitosis 

You taught me something in 13 minutes that my college professor spent 2 classes going over. Best part is, I understood what you were actually saying.

when our teacher doesn't even teach and just tells us to watch these videos

Love how we all came here cuz of our bio teachers assigning this for homework.

Paul Anderson has actually been to the White House and Space Camp because he won the award of "Best teacher in Montana". Congratulations and thanks for the videos, I live in East London and these videos are still relevant to me :D

You are the best professor. You talk very clear, and you explain very well. You never wasted the time of the students. May god bless you.

you have saved me in so many science courses i can never thank you enough! i wish my professors were half as good as you, thank you so much!

U SIR ARE A GENIUS AT TEACHING!

10:44 The sound of the cytoplasm dividing is rather horrifying, almost demonic.

How to learn 40 pages in a 13:35 minutes pre-exam? Just like THIS! Thank you, I owe you one beer!

Brain and muscle cells only go through mitosis once as we are developing as embryos, afterwards they stay in a perpetual G0 state, meaning that we usually stay with the same number of brain cells for the rest of our life. The reason why neurons and other cells such as these ones don't divide is because a cell has to stop performing its function as it undergoes mitosis, which is bad if the cell dividing is a neuron. Imagine if the neurons in your body begin to divide and stop performing their functions, you won't be able to send an electrical stimuli from your brain to major organs and your heart will stop beating, you're lungs will stop breathing, your brain itself will stop working and so on. That's why we have a limited number of these cells and they can't perpetually divide like the rest.

seriously. seriously. words cannot even describe how helpful this video was. THANK.YOU.

No one: The demons in the back of the classroom: 10:44

Incredible description. All of these videos are easy to understand thanks to the logical metaphors that AREN'T "babied down". Excellent!

Thanks Mr Anderson. I relied heavily on your videos. They are great, brief, informative and with great delivery.

Thanks for helping me pass my biology tests so far!! Your videos put great visuals in my head and help me understand better!

I love this guy! He helps so much with HW. I like the part at 10:42, something happened in the background and it threw him off for a second.

WTF happened between 10:41 and 10:48

its become my tradition to watch mr.anderson before a bio test. thx.

Your videos are so helpful, please don't stop making them! The diagrams are so easy to understand!! Thank you!

Your videos are the only ones I can watch when I need to learn something for class and be entertained at the same time.

I love how you explained!! It so easy to understand !! Thank you :)

your lessons are so helpful for my biology class. You make everything clear and easy to understand. Thank you for taking the time to make this videos. Please never stop makin them. Blessing ur way.

I love your videos and have been watching for over a year. Thank you for jogging my memory with each new video. I appreciate what you do, thank you bozemanbiology.

Istg this man is my entire biology schooling. Thanks man.

Our professor referred us to use you as extra help - and he was right. You are amazing

"I hope this helped" my guy, you're getting me through college bio because my professor doesn't know how to explain things.

I watched this in addition to the "Phases of a Mitosis" video and it helped a lot! Thanks!

Thank God for this guy and Mr. Khan, because I would be lost without them. No teacher is better than these guys!

I needed to refresh my memory and this was perfect. Thanks.

Thanks for posting such wonderful explanations!!! You save my life, I was lost with my teacher's lecture, but you clearly gave me a right, clear, and super explanation!! Thanks again :)

You have the clearest and most concise videos. Thanks!

I don't know what I'd do without your wonderful videos! Probably not get those A's I've been getting in all my classes! Thank you!!!

This helped me so much! Thank you for breaking it down and explaining it thoroughly!

this is just too good. never stop making them please.

This lecture helped me pass my first A&P exam yesterday. THANK YOU SO MUCH for these. I'll definitely be back as I progress through my class, since my teacher isn't the best at lecturing...

Thank you so much. I love your dedication. Thanks for up loading the video.

Thank you SO much! This helped me a huge amount. It makes a TON more sense now.

WOW....you are awesome! The way you are teaching this is just perfect, your videos, the graphics, your drawings...just perfect! I applaud and thank you!

I have a test tomorrow too,I understood more from your 13 minutes video than i did from all my class of genetics this year :)

You are so helpful! I never liked trying to understand biology but watching your videos fully changed that!

FANTASTIC!!! MINDBLOWING!!! UNBELIEVABLE!!!

Thankyou! this really helped my understanding. My new favourite way of revising :)

I imagine that it would be amazing to have you as a teacher for a full hour each day the entire school year. These videos do very nicely, though. Thanks for taking the time to make and upload them; they are very helpful.

My AP bio teacher doesn't even lecture anymore- he just assigns YOUR videos! :) Thanks Mr. Anderson!!!! Biology now makes sense.

I finally understood it! Thank you :)

My teacher isn't that great for Anatomy and physiology. I watched the mitosis video for the first time and I think your videos are really going to help me! You're a great teacher!!

Thank you for all the explanations Mr. Anderson. My Bio teacher in college doesn't even explain anything to us. He is making us teach the class.

And thanks for making these videos! You're doing world education a huge service.

I have a biology test tomorrow and this video helped me a lot, thank you! :)

7 people didn't see this until after their exam and failed...that's a bummer. Great videos! real life saver!! :)

SO HELPFUL! Thank you so much! Easy to follow and very informing. THANKYOU!

Great as usual!! Thanks a lot!!

Your videos are FANTASTIC!!!! They will be the difference between a C- and an A+. Thanks a ton.

Hi, I am Spanish speaker and I am taking soon my GED test. I love the way you explain it. thank you, it helps me a lot. I love you handsome .

You have the gift to make others understand and appreciate Science. Thanks for making these videos!

I love you Mr. Anderson!

You are the One, Mr. Anderson.

Dude I don’t know how to thank you enough fr a real help thanks man 🙏

YOU ARE BRILLANT!!!! thank you so much !

Thanks heaps! cannot imagine how i'd make it through high school without vids like these! i swear, you are amazing!!

Your the best . If it wasn't for you Mr Anderson, i would never understand biology! You make Biology so great.

thank you very much for this video, i downloaded it and use it in my class, this was really helpful.

Love all the videos you do mr. Anderson!!!!

You are awesome at teaching and have helped me understand science in a different way! THANK YOU :)

thank you so much for explaining this concept so clearly

Your teaching is fantastic. Thank you very much.

Thank you so much for clarifying this confusing topic.

Thank you soo much for posting these videos. I made a playlist of the topics covered in each unit and got an A on my final exam :) .

very easy to understand, i hav read many books concerning mitosis and meiosis, but i now understand it better, thank you very much

Thanks so much! This was extremely helpful! Good luck on anyone who has a bio test today/tomorrow

Thank you for subtitles!

God bless you, brother. You are a pleasure to society.

Your the best Mr. Anderson!!!!

I have my bio final tomorrow and your videos have helped me so much. Thank you!

Wow! Your videos help me understand A LOT more than my bio lectures! Thank you so much!

This made my studying a lot easier. Thanks for this video.

I love these videos. Very helpful.

im in bsci 105 at umd and your videos are extremely helpful. Nice and clear.

I am having an exam tomorrow, and after watching your video I have a pretty good understanding about Mitosis. Thank you sooo much!

This was extremely helpful. Thank you!

Excellent video! Thank you!

Dear Mr. Andersen, thanks for making biology sososoo easy. Sincerely, Your loyal youtube student :)

Dude you are the best teacher I have seen!!!!!!!

you are AMAZING at explaining things. You just covered the content of my second-year university lecture in a fifth of the time. and much more satisfyingly. IF you ever get bored with teaching biology (which i doubt) you should teach people how to teach!!!

thankyou so much! You explain everything so well! I can actually understand it!

This is very helpful for my Exam tomorrow.. thank you so much Paul Andersen!

Excellent videos, the perfect teacher.

Your videos are so helpful! Thank you so so much for your help! You are a wonderful teacher!

Such a great video thanks!

Thank you! Great job!

Mr Anderson is a genius, I love your school!

Thank you so much for posting this video! It helped me study for my bio test!

I love your videos. They have been a great help for me in my BIO 181 class.

Thank you so much, you have definately explained it much better than my biology lecturer!!!

Thank you very much!

i'm so glad my ap bio teacher has us take notes from your videos :)

Love the videos. Thank you so much!

Great explanation! Associations really help.

ur d best teacher iv ever seen !

Great review!
