But I have faced lack of income and staffs decided to leave. Please can you connect me to foundation which I can get fund to continue helping young growing child. Your faithfully.

Hi. I am a high school freshman who planned to take all the AP sciences in my sophomore year, and I initially felt daunting as I didnt know what resource did I need. However, after seeing your video and your enthusiasm in teaching biology, I am feeling less nervous about the exams! you are truly the best teacher and you deserve it!!!! wish you all the best sir

For the last question, wouldn’t the values further right on the graph be slower, since the rate units are ms/codon. Is it showing that the more milliseconds it takes to translate one codon, the slower the rate or am I reading the graph wrong?

I’m cooked

Hey! This was a great video. For 1aii, I think that your answer is what I originally thought, but I think here the idea is that if the sister chromatids crossed over they would have either 0 or 2 fluorescent markers. Since some haploid gametes will only have one, it means that crossing over didn’t occur. I think the right answer would be that, “Some of the haploid cells formed after meiosis will have only one fluorescent marker because the sister chromatids on each homologous chromosome that eventually separate into haploid cells were not involved in crossing over.” or at least something along the lines of what I said. I could be totally wrong though :)

For question 1 d.i., I said that the number of copies of chromosome 8 would increase and my justification for d.ii. was correct. Would I likely lose the point for di since I didn't mention that the number of copies could also decrease?

Do you think that the curve for this year will be lower or higher then previous years? Like will we need less or more points to get a 5? How many points is it normally out of 120?

For question 3 b), will mentioning reducing bias in the results count?

For part 1di and 1dii, I predicted that there will be a fewer number of chromosome 8 in the cells and I basically justified it as you said it (fewer would align & separate properly) but did not mention nondisjunction. But, my prediction was not the same as yours because you said there will be an abnormal number due to nondisjunction (more/less). Do you think that will get me 2 points, 1 point, or 0 points altogether?

i watched literally all your past videos in prep covering the frq in prep for this 2024 exam, and i love how enthusiastic and reassuring you are!! they have helped tremendously, you seem like a kind soul and a great educator. your energy is contagious and thanks for these!! i’m a little nervous for how i did lol. but seriously, these videos are awesome and i recommend them to my friends!! keep it up :)

I lead a organization at scholl and i am with my freind luca we are 2 leaders and we are in a crisis so i need to be divide an conquer right now 😅

peep game and lock in

Watching this 2xspeed 15 mins before exam

Mr chow saved ap bio

Here is the link to what the college board is looking for. A bit shorter than his answers, but I like how he goes into detail so I can understand it again. apcentral.collegeboard.org/media/pdf/ap23-sg-biology.pdf

watching this 4 hours before the exam. yall i am cooked. this made me realize i cannot do the frqs

Thank you sir

thank you so much!! your explanations were amazing and i appreciate the ending thoughts.

You are a saint, my biology teacher explained this once in class, thank you so much.

I have a few hours left I am def cooked wish me luck guys

22:27

i am watching this 5 days before AP bio exam in 2024 this helps so much! Thank you!

24:00 would it be right if I say The natural environment can affect the phenotype and genotype of a environment, once co2 increases the mitrochondria surface area increase resulting as cellular respiration. Genetic variation

14:53 i got 3,360% 😊

Wonderful video man! I'm thinking about starting a club in my town and this really got me thinking. I will try to apply all these great points to hopefully be a good leader. Thanks!

Hey Mr. Chow! I just wanted to make a quick correction: most AC units actually use a heat exchanger in the outdoor condensing unit to cool off the hot air that flows into it (just the exact opposite of the furnace's heat exchanger, except that the hot metal is replaced by an air pipe), which means that no outside air is ever pumped into your home; all the air in your HVAC system generally is just the recirculated air from your home.

Hi Mr. Chow! This is Sophia C. 1. The thing that I took away from this lesson was that giving generously will impact not only our lives and the people we become, but also impact other people's lives in positive ways. 2. I will begin practicing generosity today by thinking about ways I can donate and benefit my community and others. 3. Being generous is important to me because it motivates me to become a better person and use my money to positively impact others' lives.

1. generosity humbles, and it is true. After donating a month back, I became more humble than I was. This just affirms it. 2.I'm gonna really need to be kinder to people. Normally I don't say much but I should come out of my comfort zone and be nicer. 3. Because the people in the community are worth just as much as me if not more, so I should make the world a better place by giving. Everyone should experience generosity.

Hi Mr. Chow, so I have a question. Is it better to buy a new car or one that is used but still good quality? Often times online when I want to buy a book its generally cheaper for me to buy a used copy in good condition. Is it the same for cars? Do the topics you go over apply to used cars? Is it a different market?

Hi Mr. Chow! This is Pranav. Hope you are having a great winter break and thank you for taking your time and creating this finance course for everyone. I have learned a lot regarding finance and greatly appreciate all that you have done for me. One takeaway from today’s lesson that will really stick with me is that the richest person seems not to be the one with the most money, but the person who can say that they have been the most generous. I intend on practicing generosity today by creating a gratitude note for family and friends, to remind them how grateful I am for them. Being generous is important to me because it shows me how people can give to others who truly need it, and how those who are not even financially rich can still be generous in different ways. Thanks again for everything you have done!

sir can i talk about the soil for Question no 5a, like the factor that limits logistic growth is the desired soil for the ragweed plants, or is plowing and limited space the best answer to this question.

i got 3360 percent for one of the questions but i think i put the bigger number first in the formula and then bigger one on the bottom would they still accept that?

For #6 part D, I wrote about how cells can use different promoters and some cells may undergo alternative splicing

Appreciate your effort helping your students!

Taking the make up AP exam tomorrow and this (along with the other year videos) was immensely helpful, thank you so much for making these videos!

i took the exam in the middle east. Thats not my exam. Is it different for every region?

Absolute legend 🙏 this was an amazing video thank you so much

These are awesome. So so helpful.

ur so beautiful for this thank u mate

Thank you so much Mr. Chow. Because of this, I might actually pass my FRQ Final tomorrow and possibly score decently high on the AP test 👍Amazing video and nice job breaking down the problems and explanations! really easy to follow along overall

Thank you for the video. This video helped me a lot understanding the questions. I admire how you solved the problems and made presentation by yourself, taking that much effort and time for students on internet, for FREE. I appreciate so much. 🥲🥲🥲🥲🥲🥲

thanks, the video helped me through when studying

Awesome man really helping me prepare watched the whole thing you make it make total sense

thank you for making this

Thank you Mr. Chow! I was looking for a great way to help my students in my Math @ Work Class get a bigger picture about the costs involved in growing up. Your series is awesome. I am using this video as a link to their project on Car Loans and Credit cards. Keep up the great work!

for frq 2 part B, could you make a histogram instead or would that be incorrect

I am doing the five lectures

Thanks for this!

As always, thank you Mr. Chow for another amazing life lesson. Hope you’ve had a wonderful holiday!
