  • Biology - B5
    • Inheritance
      • Genome
        • Entire genetic material of an organism
        • Interacts with the environment to give the organism characteristics
          • e.g weight
        • Leads to variation within a population
      • Variation
        • Discontinuous
          • Something with a limited number of possibilities (specific)
          • e.g blood group
        • Continuous
          • Something with a wide range of possabilities
          • e.g height
        • Leads to different genotype and phenotypes
      • Mutations
        • Random change in a gene or chromosome
        • Happen contuinuously
        • Starts to eventually change species - Leads to wide range of the same species with different phenotypes
      • Sexual Reproduction
        • Male and female gametes join to create a zygote
        • You have 23 pares of chromosomes - 23 from mum and 23 from dad
      • Meosis
        • Stat off with a parent cell where the chromosomes make copies of themselves. Similar chromosomes pair then the cell splits into two and the chromosomes divide
      • XY = Male, ** = Female
    • Natural Selection and Evolution
      • Classification System
        • The Five Kingdoms
          • Animals
          • Plants
          • Fungi
          • Protists
          • Prokaryotes
        • Further Divisions
          • Phylum
          • Class
          • Order
          • Family
          • Genus
          • Species
      • Natural Selection
        • Charles Darwin
        • Organisms that are better suited to the environment survive
        • Overtime it created evolution
        • 'Survival of the Fittest'
      • Evidence for Evolution
        • Fossils
          • Where they are in the ground - higher up = newer fossils
        • Trees
          • Look at branches or rings in the roots
        • Development of Antibiotic Resistance
        • MRSA
