Biology tutor near Long Beach, CA

The Student and Tutor reviewed key concepts in carbohydrates and lipids, starting with defining carbohydrates and their types (monosaccharides, disaccharides, polysaccharides). They also covered the relationship between monomers and polymers, the types of chemical bonds involved, and the varying solubility of carbohydrates. The session then moved to lipids, explaining their definition, types (triglycerides, phospholipids, steroids), and differentiating between saturated and unsaturated fatty acids. The session concluded with a plan to schedule another class to complete the remaining practice questions.

The Student and Tutor completed their review of the respiratory system, focusing on gas exchange mechanisms and breathing regulation. Subsequently, they began an in-depth exploration of the gastrointestinal system, covering its overall anatomy, the five stages of digestion, specific organ structures, and the regulation of gastric secretions. They plan to continue with GI Part 2 and nutrition in the upcoming session.

The Student and Tutor reviewed several microbiology topics, including inclusions, the prokaryotic plasma membrane, endosymbiotic theory, endospores, and glycocalyx. The session then transitioned to fundamental chemistry, covering the definition of chemistry and matter, the structure of atoms, elements, electronic configurations, and the formation of ions (metals vs. non-metals). The Student practiced determining electronic configurations and identifying ion types, and they planned to continue with chemical bonds and other chemistry topics in the next session.

The Student and Tutor reviewed evolutionary biology concepts, including Darwin's theory, natural selection, genetic variation, speciation, and the fossil record. They practiced calculating allele frequency and constructing phylogenetic trees. The next session will involve further practice questions.

The Student and Tutor reviewed key concepts in Unit 4 of AP Biology, focusing on cell communication mechanisms (autocrine, paracrine, endocrine, synaptic) and the stages of cell signaling (reception, transduction, response). They then delved into the cell cycle, including interphase, M phase, checkpoints, and mitosis. The next session will cover Units 5 and 6.

The Tutor and Student reviewed the innate immune system, covering physical and chemical barriers, and the formed elements of the blood that constitute the second line of defense. They discussed cytokines as immune cell messengers and detailed the process of phagocytosis, including its various stages. The next session is planned to continue the discussion on inflammation.
