Hi, Patience here... watching from South Africa, taking my paper 4 tomorrow.Thank you so much for all the videos,i have been self-tutoring following all of them.Paper 2 went well, hopefully tomorrow will be the same. Be blessed abundantly ma'am.
my name is krishna,i live in the little island of mauritius and my mom is from india and thanks to you i don't take any tuition[can't afford to]and doing my bio revision as a sc repeater
Ma'am if they have told us to count flowers in sample and one of the flowers is being cut by the sample wall at its center. Will we count it as a half?
Hope This Helps!!!! Good Luck for the paper tomorrow [00:00] The video discusses how to answer a question on paper 4 and emphasizes seeking guidance from Allah in all exams of life - The question involves investigating the effect of Ami L on cooked rice - The method involves preparing two beakers of rice, adding distilled water and 1% amas solution, and keeping them in a water bath at 40°C - The video warns against not following the method correctly and emphasizes the importance of seeking guidance from Allah in all life decisions [02:40] Procedure for testing beer samples in the lab - Beer samples are left in a water bath for 10 minutes - Two test tubes are labeled W10 and A10 - 2cm of liquid surrounding the rice in Beaker W is removed and put in test tube W10 - 2cm of liquid surrounding Beaker a is removed and put in test tube A10 - 2cm of Benedict is added to both test tubes - Test tubes are put in a water bath at 80°C for 5 minutes - The color of the contents of W1 is observed after 5 minutes [05:19] The video discusses a practical experiment involving beakers, rice, and water baths. - Two beakers were prepared, each containing 20 grams of cooked rice - One beaker was labeled W and the other A, and both were placed in a 40°C water bath - 20 cm of distilled water and 20 cm of 1% MiL were added to each beaker - After 10 minutes, a glass rod was used to stir the contents of Beaker W - 2 cm of liquid rice from Beaker W was transferred to a test tube labeled W10 - Steps 7 and 8 were repeated with Beaker A - The test tubes were kept in a water bath at 80°C [07:58] Conclusion: Rice contains starch which is broken down by amas to produce reducing sugar - Observation: Color change from blue to orange in W10 after adding Benedict solution - Table preparation: Record results shown in Figure 1.1 with separate headings and units - Units: Include units such as minutes or seconds in the heading - Conclusion: Starch is broken down by amas to produce reducing sugar in rice [10:44] Variables kept constant in the investigation; the purpose of adding distal water to cooked rice label W - Mass of rice kept constant at 20g - Type of rice kept constant as white rice - Temperature of water bath kept constant at 40°C - Time in a water bath kept constant at 10 minutes - Volume of water and M solution kept constant at 20cm - Sample size removed kept constant at 2cm - Distal water added to cooked rice for control comparison [13:25] Control experiments are important to prove the effect of Mias on starch breakdown - Control experiments are used to compare results with and without Mias - Step three, adding distal water, must be carried out before step four, adding Mias - If step four is carried out before step three, the W10 sample will also change color - A thermostatically controlled water bath can be used to maintain the temperature at 40°C [16:08] Maintaining temperature in experiments is crucial, and cooked rice can be tested for starch using iodine solution - Thermostatically controlled water baths or insulated containers can maintain temperature - The presence of starch in food items like potatoes or apples can be tested using iodine solution - Graphs can have different shapes like peaks, increases, decreases, or plateaus - Describing the effect of temperature on the activity of ML requires no biology explanation, only observation of the graph [18:50] The activity of amas or mass of reducing sugar increases and then decreases, with the optimum temperature being 35°C. Rate at 42°C is 6 mg/min. - Describe is an explanation of the graph, with marks awarded for correct interpretation - The rate of MLAs at 42°C is 6 milligrams per minute - To obtain a more accurate value for the temperature at which mlas works best, further experimentation is required [21:31] Understanding the meaning of "accurate" is crucial for answering a question on obtaining a more accurate value - Test at smaller intervals of temperature to improve accuracy - Select a narrower range of temperatures around the optimum value - Pay attention to the wording of the question and understand it properly
@@happygamer1691 I did solve the paper ( I think u were talking about me ) I write these as important pointers that u can go over after u have watched the video for a quick recap ( hope it helps )☺
Ma’am I came here to thank you for uploading these videos my school was really bad and taught nothing my teacher didn’t know how to teach so I started studying from your channel from chapter 1 till the last chapter all I relied on were your lectures solely and I received my result yesterday alhamdulillah I got an A in biology because of you jazak’Allah ❤️
Is this the full p4 guide or just question 1? If only q1 can u please cover entirely the paper 4 it would help alot. Had maths p2 today too so very tired 😢
Ma’am can you please make a guess paper video for 9700 p22 as you did for 5090 previously it would really really help out ma’am. Please do consider the request ma’am
Aoa Ms Saira. I have a two questions to ask: 1. One on which says, ‘State how you could show that cooked rice contains starch’, so wouldn’t we compare it with the method listed above as such it is broken down into maltose by the enzyme amylase and maltose molecules make up glucose molecules and such Benedict’s solution is a test for reducing sugars. I am confused because wouldn’t it be also a way to show that rice contains starch? 2. Two for magnification, our drawing should be at least of 30mm which is 3.0 right?
Asalmulaikum Ma'am. My bio Atp paper is on 15th oct, I'm watching all your Atp videos. Will that be sufficient along with a few yearly papers(3-4 years) from both igcse and o level? Or do I need to practice topicals prior to 2017?
Easiest exam paper I've ever solved...Nothing new just that there was not the long experiment/investigation in question 1 instead there was the drawing question(Q.1(a)).The 6 marks inverstigation question had small detail in the question and it was question no.3. Btw, can anyone tell that were we supposed to count the extra plant specie E in question 2 or not? Some of my friends included it and wrote 10 while some didn't include it(wrote 9) while some wrote like 9.5/9.6...I think if I'm correct here then i can easily get 37-38/40 but if i'm wrong then i hope they give carry forward marks for it(the question wasn't that long too..even if they deduct the marks it'll be 4-5 marks possibly)
Assalam Alaikum mam, in my paper 33 there was a 4 mark question of making a bar chart and instead i didn’t read question and made a graph, but i labelled the graph and made a scale, so will i lose all 4 marks or get 2 marks for the scale and labelling of axis? please answer i’m very stressed
Mam How many papers should I do for tomorrow's paper ?? As i have done 5 in mock of all varients and i got 34 marks...and mam do we have to practice o levels papers na ,,,i am in o levels....plz tell me thanks😊
Mam i cleared 90 percent of bio Cambridge syllabus and the p2 questions were totally new a different style like they were too easy but i was unable how to interpret my answer 😢
Miss, i wanted to ask that is it possible to cover the syllabus of biology 5090 in 3 months starting from zero cz i currently know nothing about it. And if it is can i appear in upcoming October November session and still expect an A*??
Nooo Definitely not Its no joke You need one year at least if you are of average intelligence If below average then 2 years If highly intelligent still one year as you all cannot focus Your generation has to waste time on social media You all cannot help being addicted to your phones Rest is upto you This is not a situation of haste Learn a subject properly Then be brave enough to weather the storm of the exam Best of luck This is my opinion You maynot agree with it
Thanks a lot, I was really confused about it but u helped me to make it clear. I further wanted to ask is the biology book by Dave and Mackaen the best one to use??

@@docsaira miss in the atp paper 5090 they asked us what we will do so it was an open question?
Hope This Helps!!!! Good Luck for the paper tomorrow
[00:00] The video discusses how to answer a question on paper 4 and emphasizes seeking guidance from Allah in all exams of life
- The question involves investigating the effect of Ami L on cooked rice
- The method involves preparing two beakers of rice, adding distilled water and 1% amas solution, and keeping them in a water bath at 40°C
- The video warns against not following the method correctly and emphasizes the importance of seeking guidance from Allah in all life decisions
[02:40] Procedure for testing beer samples in the lab
- Beer samples are left in a water bath for 10 minutes
- Two test tubes are labeled W10 and A10
- 2cm of liquid surrounding the rice in Beaker W is removed and put in test tube W10
- 2cm of liquid surrounding Beaker a is removed and put in test tube A10
- 2cm of Benedict is added to both test tubes
- Test tubes are put in a water bath at 80°C for 5 minutes
- The color of the contents of W1 is observed after 5 minutes
[05:19] The video discusses a practical experiment involving beakers, rice, and water baths.
- Two beakers were prepared, each containing 20 grams of cooked rice
- One beaker was labeled W and the other A, and both were placed in a 40°C water bath
- 20 cm of distilled water and 20 cm of 1% MiL were added to each beaker
- After 10 minutes, a glass rod was used to stir the contents of Beaker W
- 2 cm of liquid rice from Beaker W was transferred to a test tube labeled W10
- Steps 7 and 8 were repeated with Beaker A
- The test tubes were kept in a water bath at 80°C
[07:58] Conclusion: Rice contains starch which is broken down by amas to produce reducing sugar
- Observation: Color change from blue to orange in W10 after adding Benedict solution
- Table preparation: Record results shown in Figure 1.1 with separate headings and units
- Units: Include units such as minutes or seconds in the heading
- Conclusion: Starch is broken down by amas to produce reducing sugar in rice
[10:44] Variables kept constant in the investigation; the purpose of adding distal water to cooked rice label W
- Mass of rice kept constant at 20g
- Type of rice kept constant as white rice
- Temperature of water bath kept constant at 40°C
- Time in a water bath kept constant at 10 minutes
- Volume of water and M solution kept constant at 20cm
- Sample size removed kept constant at 2cm
- Distal water added to cooked rice for control comparison
[13:25] Control experiments are important to prove the effect of Mias on starch breakdown
- Control experiments are used to compare results with and without Mias
- Step three, adding distal water, must be carried out before step four, adding Mias
- If step four is carried out before step three, the W10 sample will also change color
- A thermostatically controlled water bath can be used to maintain the temperature at 40°C
[16:08] Maintaining temperature in experiments is crucial, and cooked rice can be tested for starch using iodine solution
- Thermostatically controlled water baths or insulated containers can maintain temperature
- The presence of starch in food items like potatoes or apples can be tested using iodine solution
- Graphs can have different shapes like peaks, increases, decreases, or plateaus
- Describing the effect of temperature on the activity of ML requires no biology explanation, only observation of the graph
[18:50] The activity of amas or mass of reducing sugar increases and then decreases, with the optimum temperature being 35°C. Rate at 42°C is 6 mg/min.
- Describe is an explanation of the graph, with marks awarded for correct interpretation
- The rate of MLAs at 42°C is 6 milligrams per minute
- To obtain a more accurate value for the temperature at which mlas works best, further experimentation is required
[21:31] Understanding the meaning of "accurate" is crucial for answering a question on obtaining a more accurate value
- Test at smaller intervals of temperature to improve accuracy
- Select a narrower range of temperatures around the optimum value
- Pay attention to the wording of the question and understand it properly
