Causes and Effects
Non-Infectious Disease: Causes and PatternsNon-infectious diseases such as cancer, cardiovascular disease and type 2 diabetes have no pathogen: they grow out of genetic, environmental,…drag it →
Causes of Infectious Disease
Koch, Pasteur and Germ TheoryBefore germ theory, disease was bad air and imbalanced humours.drag it →
DNA and Polypeptide Synthesis
Protein Structure and the ProteomeA protein is one chain of amino acid monomers joined by peptide bonds, and every higher level of its structure follows from the order of those…drag it →
Epidemiology
Epidemiological Studies and Their ValueEpidemiology finds the causes of disease by counting it in whole populations instead of experimenting on individuals.drag it →
Genetic Technologies
Cloning organisms and genesReproductive cloning makes a whole organism that is genetically identical to another, either by splitting an early embryo or by somatic cell…drag it →
Genetic Variation
Meiosis and genetic variationMeiosis copies the DNA once and then divides twice, turning one diploid cell into four haploid gametes.drag it →
Homeostasis
Blood glucose regulationBlood glucose is held near a set point by negative feedback between two pancreatic hormones.drag it →
Inheritance Patterns in a Population
Population Genetics and Large-Scale StudiesZoom out from one pedigree to a whole population and genetics becomes statistics.drag it →
Mutation
Types of Mutation: Point to ChromosomalMutations range from a single swapped letter to whole chromosomes gained or lost.drag it →
Reproduction
Sexual and asexual reproductionThere are two ways to make more of yourself: copy one parent exactly (binary fission, budding, runners, parthenogenesis) or fuse two gametes at…drag it →
Responses to Pathogens
How Animal Hosts Fight BackBefore any antibody exists, an infected animal is already fighting: barriers, fever, inflammation, cells that eat invaders whole.drag it → Plant Defence Responses to PathogensPlants have no antibodies, no white blood cells and no way to run, yet most plants resist most pathogens.drag it →
Technologies and Disorders
Disorders of Organs and Assistive TechnologiesA cochlear implant, a dialysis machine and a pacemaker do not repair damaged tissue.drag it → Kidney failure and dialysisThe kidney is homeostasis hardware: a million nephrons filtering blood, balancing water and salt, exporting waste.drag it →
