The one that I sent last time is starts with biology revision guide, page seven, 216. Remember to mark your question answers, and then write the functions of I remember. And then write the functions of the different organelles. You got up to 15. I have finished 15. Okay. So you remember 15 did you read all the pages up to 15 then? Yeah, okay. So that means you did twelve as well. Twelve and 77. Yeah but some of its finished too. Okay. Do you remember how well they went? So I can note down if things were difficult, the exquestion to one. And two we 22.1 strong and for the six. 2.1, is it just 2.1? Or was it 2.1 and 2.2 and two prookay nice. So page seven, all of three. And then for page twelve. No down. Oh, you haven't done page twelve. How can you skip it? I don't know, I just. Can you say that again? I mean, I'm in the page twelve. Have the question. Oh, you didn't see it. It Yeah it does. Right before culturing organism microorganism. Oh, my God, I'm not. The time is tough. You didn't see it. Yeah. But how come you missed it out? Like did you accidentally turn to pages or something? Hello, how did you miss it when you were doing the homework? You mean the page twelve? Yeah, I don't know why because I found the maybe okay, so that means you probably haven't read page 13 either, right? That's is that right? You haven't seen page 13 either. So next to page twelve, you don't recognize that page, the culture and organisms page, I see. Yeah. Do you recognize it? Okay, that's fine. And just I'll make a note in your homework for the coming week. Page 1213. All right. And and how come you didn't do? Let me see. How come we then do 16. Did you just not have time or did do you forget? 16. Yeah. 6:16 didn't have a question. Sorry, the reverse sumties for types one a. Yes, Yeah, that one. I don't know how to do this. You just there's, you just go through each question and then write your answer. Oh, why? Yeah, you can there's sample answers as well. It says on the. Wait. Yeah if you get to the website it says the the gp books dot code at uk slash leaf you get all the answers as well. Also have a 29 question. Yeah but these are meant to be like as long as like from learning topic one a, you should be able to answer all of them. So it also helps to identify if there's things you didn't remember. Okay. Yeah okay. So you were just confused on how to do the test. Okay, that's fine then that done too. But now is it clear how to do it now? Yeah, awesome. Yeah. It's really handy because if there are ones that you've got wrong, then you know that you should focus on remembering those. I guess that's the same for any question, but especially for the revision ones because they're kind of like summarize everything we learned. Okay. Do you have any specific things you want to go over from what you've read? Or shall we continue reading now? Maybe you isn't can't keep. Diffusion then right Yeah the. The vision is about the movement of Ted definis, the ground deal movement to of parlic from place where there are lots of them to play where they are of them. It's just. Is neutron. Natural tendency. Tendency. Of of to spin out, you also have learned when way of saying the same thing. Definition tion is out of depenfrom the area of higher competition concentration concentration concentration to an area of a lower conversation. Does that make sense? Do you know what concentration is? Yeah, okay. Division happens is about the. The sociis this works. Solutions solutions okay and getting essing because the this substance. Subare free of moving about the. The simptype is when different different since each other when person different sense of in room. Huh? Dualda. The bigger the conversation, the definition in conversation, the difference, right? A high temperature will also give faster, right? Because the patterhave move energy, so move above faster. Yeah. We can, if you want at half past, we can take a quick break like five minutes if you need it. No, no, it's fine. Okay. We just like I just forgot today, the lesson time is very early, because every time when have a question, I will like reading something before. Yeah, so I'm not reading today. That's okay. That's okay. How long will it take to read it? If it helps you, then you can still do it now if you want. It's okay. So. The comember is holding the cell together, but this is stop in the in and out of. They let stuff in and out as well. So they because they control what substances go in and out of the cell. If you see it, the diagram there, it shows you it lets some items in and some items it does not let in. As well. That makes sense. Yeah. Okay. So this is about the sales memory. Yes. This is because they are present present members ories. They have very similar holders. Wow, very similar hours. And. They have a burit this. The lower subhow substances dissolve substances. Substances substance is substances. Substances substances subsubstances Yeah Yeah substances. The more that we say, the more it feels like it's not a word. Substances. Yeah Yeah, nice. Okay. They very. I moving and out of south by different ition. How to understand? To understand. Yeah. Let they move in and out by diffusion. I mean these subcan and out of by Yeah we'll see a question I no understand this symptoms okay so you dissolved substances do you know what that is? Yeah, okay. They can move in and out of the cells because of the cell membrane being partially permeable. Do you understand that bit? Yeah biodiffusion so it's because with the cells that not cells sorry, the substances that can move between like in and out of the cell, if there's more of this substances on one side of the cell membrane. They there's a net movement into the cell, into the cell because of diffusion, because there's a high concentration going to a lower concentration. Yeah, again, nice. Et que? 一个ecuecunice really Yeah molecules that's perfect。They did not expect it. No big mule like atand starand. The politics is. What are you can't? But why is some molecules can diffuse inserts or oxygen? I mean. Underwater. Underwater. Yeah water is a small molecule. Do you know what? Why is why what is small molecule? Because think about it. Water is made of hydrogen, oxygen and another hydrogen. Hydrogen is like the tiny, the smallest atom you can have. So there's two smallest atoms. And then oxygen is also quite small. Is 16 relative atomic MaaS. So Oh, I was detached. So this molecule itself is actually quite small. If you look at the examples of of molecules, do you know what starch and proteins are made out of? No ops. It gives you the constituent. So. Out of these four, one of them makes up starches and one of them makes up proteins. Can you guess? Yeah, which one makes some stuff? I don't know. Have you do you know what these are? Old, old four? I only know the first two. And water, what's been the amino acids is it's the smallest. It's the constituent of a protein. So it's many. If this is one amino acid, then a protein would look. Okay, 13 ting would be like a really, really long, less infinitely well, not infinitely, but a very long kind of Yeah. So that's why the amino acid is a small molecule that can PaaS through. But Prouse, I don't know. And it's similar with such ch. It's glucose. So that makes starch. Yeah, it's a similar concept. So a glucose is the simple molecule. And then the start is that times a very big number folded together. Yeah, but actually glucose itself is a lot bigger than water, because I think glucose is like C C six, H twelve o six. So you can imagine with that many molecules in it, sorry, that many atoms within that one molecule, it is already quite big compared to water. Right? But it's like these massive ones that can't get through. One massive like really large because this Oh my God, this is the glucose well if it's starts, it's the glucose time site 20 plus probably. Okay, random number, but you understand what I mean. I think. Yeah. Yeah, understand understand. Also, next time if word comes up where you don't know what it means, just ask anyway. Like it might be a small thing, but it might be because it's quite important to know what amino acids is. So we don't want to miss it. Yeah, yes, okay, awesome. Up prices flow from where this is high condition to with this lower condition. The political are only moving about reasoning randomly. So they go both ways. But if there are a lot of move particles on one side of a membrane, there's net movement from the side. The large sofarea of the memory, the first difference rate, because roof particle can pertions on once, see 20 form on why this is important difference is just politics print out, remember reading in particular, and can go in memories to area up to tion of that side one. A standing under a drop m of link to a glass of cold water. What will the strength to hope to happen to the drum of link? How made an obstthe link was added to a glass of warm water? Hmm. Do you want to try the question? Yeah easy question, okay. Maybe I'll copy it into the classroom so you can write out. Yeah, so I can write, write. Oh, that's great. My book. First message, explain your answer. When the drum of leais to cold water, the link spreadslowly to the like surrounding water. Oh and like apparenthe wow wow glasses of water turn into the color lar and of the link Yeah so because because. It's great because. The link Oh, I got it because the partiles in the link are moving. Reded, Yeah, Yeah. So so it is the temperature of the cold water ering is low, so so the movement speed of the cause is slow, and recently is a long different process. Ses, okay, do you want to write down what you would put? I write down, it's a lot of, because I just think I speak a lot of, okay, let me see what just I think because I think clearly when you're thinking out loud, you probably are saying more than I don't know when you do answers, I'll do first too cold water. The limspread slowly. To the surrounding water and. I eventually. God. Says of water. Featthe color of offer offer the link. And let me explain because. Party. Yeah. So. The. Of cold. Cold water is low. And the movie of the. Colors. Then. So. No, really. Okay. Finish. Yeah, okay, now let me do the question b Oh okay, you can take question b. No. Link. 一的哀笑，心里会看着你。Faster. And. And it's a whole. Water. The link. Color. Much more quickly much more quickly much Yeah no. What's more. Good me. Okay, can explain why. Look at how many Marks the question is. And then just one, I don't actually explain this answer. Okay, okay, let's have a look. So yes, let's have you look. I'm going to put the max scheon the board so we can look at it together. All right. Can you read that or should it make it bigger? The link will different speed out water. I think you got that threads out. Yeah, it is because the link particle will move from where there is a high condition of. To where there is a low condition of thing. Okay, I think what do you think? Well, like only say the the higher transition of ten. I'm no the lower transition. Oh no, I say I say the lower condition. I'm not saying the high condition. Okay, I think Yeah, I think we need to say specifically higher concentration to lower concentration. I think that's really important. Higher Yeah it's like the resting is a long different process, right? Sorry. Maybe pis wait. It's it's low. Okay. Yeah it's because when you're mentioning diffusion or osmosis as well, which I think you'll read about soon, you always have to say it goes from a higher to a lower concentration. Okay, just like this. No, no, you have to specifically say, come on, particles move from a high concentration to a low concentration, high condition and low condition. So Yeah. Condition no condition. Okay. So you can say. You can say. I don't think this part is needed really. You can see the hospitals move high concentration. The. Yeah, something like that. The speed of speamoved high condition and low condition. Wow. Yeah because look at the the definition for diffusion. You should know this very confidently. The key parts is the spreading, the higher concentration and the lower concentration. So it's really important. Okay. Yeah. Okay, nice. So I think you get one mark for that question. So you know how to get the other one. So let's sign. And the pink particles will diffuse that spread out faster. So you just the diffusion speed is faster. Yeah and you got that one. That's great. Yeah, Yeah, nice. Okay, let's read the next bit. Osmosis. So this is what I mentioned, though briefly. This is also about higher concentration to lower concentration, but a specific kind, okay. Well, what else do you see? Read the omespage. The page 1814. The. Osmosis. Is a special care of this out. Hmm. See I. Am at all wasn't arms. How to say it osis osmosis. I put the pronunciation more Moses. Moses, Yeah, I guess you could do that. Yeah, Moses. Moses. This sorry. Okay. Euh. Old mois, the movement of the water monitecular members, the of. Trantionally. Okay, water can PaaS through the house. Yeah, positive memory, but bigger. Water both slethis happens because water mostly all the time. But only there is a state net it flow. Oh of water from the thousof the of water moecuto the more consistsolution. This means, this means the more consultation solution gets more. The water artist like it, trying to up the consultation the side of the membrane. Do you understand that? Like 18. Percent. Okay. I think the way they describe it as a little confusing, but I'm going to try and explain it as well to you. So I'll put it. On the screen. So you understand diffusion, right? Diffusion is moving from a high concentration to a low concentration. Here it's the same just for water. For water, we say like I think they're confusing because they say more dilute to more concentrated, which is technically correct. If you're looking at the solution that a more concentrated solution has a less has a lower concentration of water molecules. So osmosis is a high water potential, high concentration of water molecules to a lower concentration of water molecules. Because it's only the water that's moving. So it's the same as diffusion. The only things is it's specific to water. The water is moving and you need to be going through a partially permeable membrane. Does that make more sense? But I suppose if you want to describe it as a higher to lower concentration, you need to say higher water potential to a lower water potential because I'll just write that. Okay, I got it. Because like they said, when you're saying concentrated, it's normally about the solution, what's dissolved in a solution rather than the water, isn't it? Yeah. Make more sense. Yeah yay. Okay, nice incarry on. You can wear how good afriplant. This. Is just one way of a shower all at work. Didn't worry if you see slebin use. Oh. This is a very classic experiment. You might even do it in class. In class, I don't. Do you do experiments in school? No, no, maybe. You can do it at home if you have a scale. What? At home? Yeah, just crazy. Holiday at home. Wait, let me tell. Holiday when. Into in and get some work with. Why should we put water and all should be a very condition sugar in smosee, you can have free other with consumption in between. Now messaging the MaaS of because it was should be the home. Wow, Yeah, it's not. Yeah. Mostly sliand, most of the, they leave one condition in each break of the twelve of hours after the time, take them out, day, take out, join them with the, with the paper twelve. Twelve and win again. If the candies have a drwater by theyhave increased in MaaS, if water has been drawn out and drown out there, have a death in MaaS, you can counlater the change in MaaS. If water has been drwn well, if they have a in mind, then pull for. Okay. Wait, it is. We need help, please. No, I just try to understand the, the, in the box. I'll sentence in the box. By conducting the change, you can copy complete the acting. You can compare the effect. Condition on kindly the data help to similar. 马。What is this initial? No, it's. An is must as well give a positive change and will give the negative change. The valuand, the independent able is the conof, the sugar solution, all of the varimust be kept the same, or of the experiment won't be a full test. Like an experiment you need to be, for example, is some pors Canadians were not afraid of citizens. The extreme water would give high MaaS, or water from the, is the consultation of the sugar. So she would change. You can read the if of this three or so by repeating, so if. But so. Also. Hello word. Which word? I don't know where you are, where are Yeah what is the sentence sense a poo R A D? Evaporated of a water ated evaporated from the break the consumption of sugar. Okay. Okay, susolution would change your Carry by the of this is by repeating the experiand mean change at each condition almost equal difference of water. Just remember all things is just the difference of the water mounapparenhorble memory e okay, finish. It's too long. But that was good because osmosis and the future are super like you need to know them. They're like key parts of biology. So it's good that we got we got through it right okay, I will I will leave you with this. Merry Christmas. Although we're not going to see each other until after Christmas. Soul, well this is meant to move. I don't know why it's not moving. It's like a little the reindeers are meant to be moving but I guess it Oh, but yes, I will see you. Do we have any plans for Christmas? No, just like eating food with my friends and my family. Yeah, ethe best esomething. Okay, sounds good. Enjoy it. I'll see you next after Christmas.
