You should start by watching the video on the AP Biology test. I have organized all of my videos on my website under the AP Biology heading. Best of luck on the exam.
I can't tell you how thankful I am for this video. I'm in my first week of AP Biology and was struggling with this concept until now. Our first exam is tomorrow and now I'm entering it with full confidence. Thank you so much for taking the time to reach out and demonstrate this concept for others!
Hi, Mr. Andersen. Your videos are highly pedagogical, fun and easy to watch. Every time that I have a new subject in my Biology class, I look at one of your videos, and even if the topic is difficult, your videos are the best guide for understanding almost anything. You are a fantastic teacher!! Thankyou for making all of these videos :) // A Swedish student
@@Anonymous-mb9mn Advanced Biology. It's a step above normal, general biology. It deals with DNA coding and stuff. Edit: and a test is just a form of academic assessment used to determine how well someone has learned/ retained information over a certain period of time.
Unicatwhal ugh are you applying? I find that UC Davis is a fair school for academics. I say this because the focus isn't really on learning, it's more on research. I felt my classes in high school were more challenging and I learned more. I currently have a 4.0 GPA, so no I'm not saying this because I'm not doing well. It's just my opinion. But good luck. I hope you get in. I changed my major to Engineering by the way(: I'm hoping to get into medical school still. I wanted to have a knowledge outside of medicine and biology, so I chose engineering.
Marjorie Barker Yes Bozeman is still very helpful in college. I am an engineering major, (changed to engineering from biology) and I use his physics videos to help me in physics and I also used his videos while taking courses in biology.
Thankyou so much these videos are so helpful they cover all the topics I need in great detail and you expain them so well! I don't think I'd pass my a level biology without you!
this 10 minute video taught me more than a 50 minute lecture. how do you find the pressure potential in a closed container? my homework examples are asking to find the water potential of a cell and as far as I can tell, the pressure potential isn't listed. all we're given is the molar concentration and the temperature. am I supposed to be able to find the pressure potential based on those givens? thanks.
how does increasing temperature decrease the water potential? if temperature increases, then it means that the particles will move faster and more randomly. this means that the eagerness of the water particles to move out increases( similar concept as pressure). but according to the formula, is T increases, then water potential decreases and this means the the water is less likely to move out. I have searched on Google several times but i couldn't find the answer. thank you
basically you use temp. in the equation to find solute potential. the higher the solute potential the lower the water potential. so therefore the higher the temperature the lower the water potential
my name is Sai and every time I hear you refer to psi, i chuckled, thanks for explaining well, also our AP Bio teacher told Us to take notes on your videos so that is what Im doing right now
Paul, there is another convention for significant figures. The rule I use does not use only figures in the answer equal to those given. it uses the all the, “certain” digits and then the first uncertain digit, but no more. So, at 8:47, I would provide -4.9 bars as the answer. In engineering, this is common practice.
First of all just wanted to say grateful I am that Mr. Anderson takes time to make these informative videos. I am still a little confused on one part though and if someone could provide clarity that would be super helpful. Why is it that when solutes are added it decreases the solute potential if it also lowers the water potential? Is it because the water will move into it eventually and we are taking the measurement after the process has happened?
I've been trying to learn about magnetically structured water for plants. I think you may have touched on how it works. Any guidance along those lines would be greatly appreciated!
Not here for AP bio, just a college bio exam 😂 this is the one thing I struggled with cause my prof didn’t show us how to solve it. Just gave us equations and told us to do it. Didn’t even give us the answers to know if we did it right. Thank you for showing me how to do it. 😂
9:25 'n so that's Water Potential 'n again it measures where is water is high as far as potential energy of water and allows us to figure out where they go.
Professor Anderson, why did you choose to utilize bars over MPa megapascals. Bars is not approved by the international system of units (SI). I would also assume since psi pressure is a physical force relatable to measurements conducted in physics studies and other STEM science studies. It is also labeled in my pearson textbook as such. I ask because the only place I have ever seen bar measurement is weather stations, and on pneumatic technology and compressors frequently.
