C$65Biology - GCSE, A level tutoring and primary school teaching
**Class Description:** This tutoring service offers comprehensive support for GCSE and A-Level Biology students across all UK examination boards. Each session is specifically tailored to the individual learning needs of the student, focusing on both the academic requirements of their syllabus and their personal progress. As a fourth-year medical student, I bring a deeper understanding of biology through advanced studies and real-world applications, allowing me to provide insight into the subject beyond the curriculum. My teaching approach goes beyond simply preparing for exams; while exam-style questions will be regularly incorporated to ensure familiarity with the format and structure of assessments, the main focus will be on fostering a thorough and long-lasting understanding of biological concepts. Homework will be assigned after every lesson to reinforce the topics covered and ensure consistent progress. Additionally, exam-style questions will be systematically reviewed and analysed, equipping students with the confidence and exam techniques needed to excel in their qualifications. With this combination of tailored tutoring, practical insight, and academic support, students will be empowered to master their Biology studies and achieve their goals. I hold advanced DBS certification, have worked with children before and also work in psychology and paediatrics within the NHS.

C$25I teach English, Greek and Spanish classes for children and teenagers.
Teacher with more than ten years of experience, I have lived, studied and worked in Greece, Spain and England. My experience with both languages has given me the ability to teach other people in a dynamic and professional way. I offer to learn about your goals, your level of English, Greek or Spanish and thus design personalized and direct classes so that we can achieve your goals together. My greatest satisfaction is communicating with my students in the languages I have already taught them. I teach the classes online because I also work for the cruise line. I greatly respect my students and their goals, but I always make it clear that mutual respect, mutual schedules, and mutual commitment are the only three points that I try to have in common with my students, since those points reflect that we are going to meet our goals. I love to bring up topics about almost everything, doing pronunciation exercises. I truly believe that if we use what we do throughout the day to create an increasingly extensive vocabulary and we are persistent, I think that in a short time we can achieve very good results. I am a specialist in breaking the ice and creating the best closeness or complicity to get the most out of my dear students, I assure you that learning English, Greek and Spanish will be fun and one of the best experiences you will have!!!

C$25plasma membrane: structure, function, properties
Structure of the plasma membrane The plasma membrane is mainly composed of: Phospholipids: These amphipathic molecules (having both a hydrophilic and a hydrophobic part) are organized into a double lipid layer. This structure gives the membrane its semi-permeable barrier property. Proteins: They are integrated into the lipid bilayer and perform various functions: transport of molecules, reception of signals, cellular recognition, etc. Carbohydrates: Linked to lipids (glycolipids) or proteins (glycoproteins), they play an important role in cell recognition and cellular interactions. Function of the plasma membrane Selective barrier: The plasma membrane allows the selective passage of certain molecules while preventing others. Transport: Membrane proteins provide passive (simple or facilitated diffusion) or active (pumps) transport of molecules across the membrane. Receiving signals: Membrane receptors allow the cell to detect and respond to signals from its environment. Cell recognition: Molecules present on the surface of the membrane allow cells to recognize and interact with each other. Maintenance of homeostasis: The plasma membrane helps maintain a stable intracellular environment by regulating exchanges between the cell and its environment. Properties of the plasma membrane Fluidity: The plasma membrane is not a rigid structure but rather fluid, which allows it to deform and change shape. Asymmetry: The two faces of the plasma membrane have different compositions, which gives the membrane polarity. Plasma membrane models Fluid mosaic model: This model, the most accepted, describes the membrane as a constantly changing mosaic of lipids and proteins.
