In 2010, I began my career as a full-time A-level Biology lecturer. I strongly believe that teaching and sharing knowledge with the next generation is my lifelong calling. It is immensely satisfying to witness my students grasp a new concept. I am passionate about education and constantly research and develop new teaching materials to enhance learners' engagement.
I have a deep interest in filmmaking and video editing, which led me to create this RU-vid Channel: D biology classroom. My aim is to help students worldwide by sharing short and concise videos that explain complex biological concepts in just a few minutes. Like, comment, subscribe, and share my videos so more people can learn biology from them!
I offer online tutoring for individuals and groups. My goal is to help students achieve their academic goals through individualised instruction. Feel free to contact me for more information: daviddelecturer@gmail.com
By far its the best video i have ever seen thank you doctorr ...it would be better if u uploaded these long sessions. and also is their a detailed criteria to answer the comparing question between slides??
Considering source definetion at 0:50 ....how its where products synthesised..in einter root act as source and it does not synthesis anything as no chloroplasts
Please upload all paper 2s and 4s of the last 5 years asap if possible. I have not found any other channel so helpful for biology and more of your videos can be of great help!...
It means when you choose the value for the scale, try to choose a multiplication of 1,2,or 5. For example, every 10 boxes are 10 or 20 or 50 is good, but every 10 boxes are 40 or 70 is not a good scale.
2(d)(iv) In summary, 3 nucleotide bases code for 1 amino acid. Also, some DNA nucleotides does not code for amino acid at all. That is why there are more base pairs in a gene than the polypeptide the gene codes for. R group is the variable group. Different amino acids have different R groups. Amine and carboxyl group are the same for ALL amino acids, so they are not R group.
Correction: Q13 - since P is already at optimum temperature, if Q has a higher temperature, it should have a lower rate. However, it wouldn't reach the same Vmax as P since enzyme has denatured.
