  1. Keywords: Adaptation, Competition, Inherit, Asexual Reproduction, Cloning, Genetic Engineering white appearance for camouflage thick layers of fat and fur for insulation a small surface area to volume ratio, to minimise heat loss a greasy waterproof coat large furry feet to distribute weight slit-like nostrils and two rows of eyelashes thin fur to allow easy heat loss a large surface area to volume ratio to maximise heat loss go for a long time without water large, flat feet to spread weight Competition A cell nucleus contains 46 Chromosomes, which carry genes and are made of DNA. Different versions of genes are called alleles. Animals -food -water -territory -mates Plants -light -water -space -nutrients • Transpiration is the loss of water from the leaves • Reduce water loss by • -Closing stomata • Small surface area leaves • Water storage Tissues • Succulent  stems that can store water widespread root systems that can collect water from a large area cacti have spines instead of leaves B1b Biology Cloning Plants: Cuttings, Tissue Culture. Animals: Embryo Cloning, Adult Cell Adult Cell Cloning Clones have the same genes Extinction, Evolution, Lamarck, Darwin, Natural Selection, Mutation, Pollution, Acid Rain, Global Warming, Sustainable Development

  2. Theories of Evolution Lamarck- inheritance of acquired characteristics Darwin- natural selection & survival of the fittest • Extinction • Changes in environment • New predators • New competitors • Disease Life started 3 - 4.5 billion years ago. Fossils show how organisms have changed • Population Explosion • More people = • More waste • More air pollution • More water pollution • Less land available • Sustainable Development • Using resources wisely • Recycle, reuse • Plan on local and global scale • Brown field sites • SSSIs
