I’ve moved over to instagram for a bit so follow me on there if you’d like to see daily GCSE & A Level Biology exam question walkthoughs, quizzes on my story and more behind the scenes content! #gcsebiology #alevelbiology #biologyalevel #alevels #alevels2024 #gcses2024 #gcserevision #year11 #gcsehelp #gcsescience
00:13Daily A Level Biology exam question 📈 Describe the test for lipids. (2) 💭 ✅ Add ethanol, shake (to dissolve lipids), then add water ✅ Positive = milky white emulsion Basic knowledge, make sure you know it. Let me know what topics you’d like me to cover next and don’t forget to download my model answer notes if you do AQA at stan.store/biologywitholivia 💥 #alevelbiology #biologyalevel #biologyteacher
00:29Here’s your A Level biology daily exam question 📈 Name the two molecules from which a ribosome is made. [1 mark] 💭 ✅ RNA (rRNA) and protein This is a niche part of the specification but it was actually one of the first questions in the paper a few years ago. Loads of students dropped the mark because they hadn’t been paying close attention to these niche details! #alevelbiology #biologyalevel #biologyteacher #biology #biologystudent
00:11A Level biology daily exam question 💥 Here are my tips for drawing condensation diagrams: ✅ Draw the H2O molecule formed ✅ Name the bond formed ✅ Circle the two groups reacting - these will include two hydrogens and an oxygen Follow along for more daily exam questions! #alevelbiology #biologyalevel #biologystudent #biologyteacher #biology
00:36A Level - Describe the difference between the structure of triglycerides and phospholipids (1 mark) ✅ One of the fatty acids of a triglyceride is substituted by a phosphate-containing group Make sure you’re revising biological molecules - it links to everything! 🔗 Would you have got this mark? 👀 #alevelbiology #biologyalevel #biology #biologyteacher #biologystudent #apbiology
00:35Describe the chemical reactions involved in the conversion of polymers to monomers and monomers to polymers. Give two named examples of polymers and their associated monomers to illustrate your answer. [5 marks] 💭 1. A condensation reaction joins monomers together and forms a (chemical) bond and releases water; 2. A hydrolysis reaction breaks a (chemical) bond between monomers and uses water; 3. A suitable example of polymers and the monomers from which they are made; 4. A second suitable example of polymers and the monomers from which they are made; 5. Reference to a correct bond within a named polymer; How did you do? #alevelbiology #biologyalevel #biology #biologyteacher #biologystudent #alevels2024 #biologystudent
01:15Describe how amino acids join together (2 marks) 💭 1. Amino acids join together by a CONDENSATION reaction, REMOVING a WATER molecule 2. This happens between the CARBOXYL group of one amino acid and the AMINE group of another 3. Forming a PEPTIDE bond How did you do? #alevelbiology #biologyalevel #biology #biologystudent #biologyteacher #apbiology #alevels2024 #biologyrevision #year12
00:38Describe the difference between introns and exons: • An exon is a base sequence of a gene coding for amino acid sequences in a polypeptide • An intron is a base sequence of a gene that doesn’t code for amino acids, in eukaryotic cells Download these model answer notes (AQA) at stan.store/biologywitholivia What topic shall I cover next? #alevelbiology #biologyalevel #biology #biologystudent #biologyteacher
00:42The key points to remember: - DNA in eukaryotic cell nucleus = long, linear and associated with proteins (histones) - DNA in mitochondria, chloroplasts and prokaryotic cells = short, circular and not associated with proteins #alevelbiology #biologyalevel #biologyteacher #apbiology #biologyrevision
01:24Understanding this is CRUCIAL to understanding so many other tooics in A Level Biology. How many marks would you have got? 👀 Check back tomorrow morning for the next daily exam question and let me know what topics you’d like to see next 🔬 #alevelbiology #biologyalevel #biologyteacher #alevels2024
